4 Introduction Congratulations on your purchase of a Glass Nexus Multi-Effect processor. Our goal is to provide musicians with premium, no-compromise tools that inspire musical performance and creativity. We believe you will find our products to be of lasting value. Glass Nexus represents a breakthrough in multi-effects devices, combining an unprecedented combination of power and ease of use. Modulation effects with incredible detail, and a reverb that sets a new standard in depth and realism combine with a 1.5 second delay all controlled by a few simple knobs. 96KHz processing buffered by dual 12AX7 s produces un-compromised signal quality of the processed sound, while the analog dry path ensures transparency. The user presets, tap tempo, strum tempo, and MIDI implementation make sure Glass Nexus delivers in any performance or studio application. Precautions The Glass Nexus s tube circuits run at very high internal voltages. Never remove the back panel of the unit. There are no user serviceable parts inside. Use only with the supplied AC power adapter. Avoid spilling liquids into the unit. Do not expose the unit to excessive heat or moisture. Refer all service and repairs to a qualified certified technician. Unplug unit when not is use. Rear Panel Connections POWER INPUT L (MONO) INPUT R OUTPUT L (MONO) OUTPUT R MIDI IN MIDI OUT Audio I/O Jacks! Multi-effect devices are typically placed after distortion effects, or in the effects loop of an amplifier if available. The Glass Nexus is a true stereo processor. The Left and Right inputs are processed independently and sent to the Left and Right outputs respectively. With a mono input, a stereo output is produced when using both outputs. The Glass Nexus can be used in three basic I/O configurations: Mono-In/Mono-Out Mono-In 4

5 Mono In-Stereo Out Stereo In-Stereo Out MIDI Connections Connecting the output of a MIDI controller unit to the MIDI IN jack of the Glass Nexus allows you to sync to clock, to control the knobs and switches remotely, and to access an almost unlimited number of Preset Locations. Connect the MIDI Out to the MIDI In of another MIDI device. MIDI messages sent to Glass Nexus will be echoed to the MIIDI Out jack. For more on MIDI, see the section under MIDI. Power Jack Use only the included Damage Control power supply to power the Glass Nexus.

6 Effect/Preset Selector This twelve-position encoder selects one of eight modulation effects, (PHASER, ROTARY, CHOIR, TREM, VIBE, FLANGER, VIBRATO, and DETUNE), or one of four Preset Banks. The encoder has a momentary push-switch that is used during preset saving. See the section on Preset Operation for more detail. Control Knobs EFFECT MIX sets the effect mix from dry (no effect) at minimum, to maximum intensity when clockwise. EFFECT ADJUST adjusts the LFO speed for PHASER, ROTARY, TREM, VIBE, FLANGER, and VIBRATO. For CHOIR, it determines the voicing, and in DETUNE, the pitch detune amount is varied. DELAY MIX sets the wet/dry delay mix, from dry (no delay) at minimum to 100% wet (delayed signal only) at maximum DELAY REPEATS controls the number of delay repeats from one at minimum to infinite at maximum. DELAY TIME sets the delay time from 50ms at minimum to 1.5 seconds at maximum DELAY FILTER sets the filter shape of the repeat filter from flat (no filter) at OFF to an analog-type shape at 12:00 to a tape-type filter at maximum. The filter morphs smoothly between these points. REVERB MIX sets the wet/dry ratio of the reverb from dry (no reverb) at minimum to 100% wet (delayed signal only) at maximum REVERB ADJUST adjusts the reverb from small-space ambience to a huge auditorium. When the knob is at minimum, a spring reverb is selected. 6

7 Footswitches ON/BYPASS A In the Effects modes this footswitch toggles between BYPASS and multi-effect ON. In any Preset Bank, step on this switch to toggle between Preset A and Bypass. For more information, see the section on Preset Operation. TAP TEMPO B The TAP TEMPO footswitch can set the Effect LFO for the LFO driven effects (PHASER, ROTARY, TREMOLO, FLANGER, VIBE, and VIBRATO) as well as the Delay Time while in any effect mode. In Effects modes PHASER, TREM, VIBE, FLANGER, and VIBRATO, step at the desired interval to set the effect LFO speed. In ROTARY mode, step to switch between the slow speed and adjustable fast speed (determined by the EFFECT ADJUST knob). STEP AND HOLD DOWN while strumming or playing staccato notes to set the Delay Time. In any Preset Bank, step on this switch to toggle between Preset B and Bypass. For more information, see the individual effects section on the Preset Operation section. LED Indicators The LED indicators offer a comprehensive survey of the state of operation of Glass Nexus. For detailed information on the LED indicators in each mode, see the individual sections under Effects Modes and Preset Operation. LEFT TUBE CHAMBER indicates the EFFECT MIX and EFFECT ADJUST settings in the Effects modes. In Preset Operation, this indicates the ON/BYPASS status of Preset A. RIGHT TUBE CHAMBER indicates the Delay Time in the Effects modes. In Preset Operation, this indicates the ON/BYPASS status of Preset B. MAGIC EYE indicates the ON/BYPASS status of Glass Nexus in any mode, glowing green when the effect is bypassed, orange when the effect is engaged, and red when a preset is engaged. Reverb The Reverb in Glass Nexus combines quality and flexibility with unprecedented ease of use. One knob takes you smoothly and continuously from a small-space ambience to a huge arena. At each position of the ADJUST knob, you find yourself in a natural space. As you turn the Adjust knob, Glass Nexus recalculates all the critical parameters of the reverb, including early reflection patterns, pre-delay, diffusion, reflectivity, damping, and density to ensure the most realistic acoustic space at any position. 7

8 The Reverb effect is always available. Use the REVERB MIX knob to set the amount of reverb, and the REVERB ADJUST knob to vary the size of the reverberation space. When the ADJUST knob is set to minimum, the reverb effect becomes a spring-type reverb. Set the MIX to minimum to turn off the reverb effect.! When the reverb transitions from spring-type to natural space, you will notice a clicktype of sound if there is a signal present. This is an indication of the transition, and is an easy way to dial in the reverb to the smallest spacial settings. Example Settings The following settings highlight only the Reverb effect, which occurs when you turn down the EFFECT MIX and DELAY MIX as shown in any of the Effect/Preset encoder positions. Ambience If you re recording dry and want to add a hint of natural space, dial in a small amount of reverb as shown. Try varying the Mix control and the Adjust control separately to see the difference in sound that results. Room This creates a nice-sized space for a solo guitar in an intimate environment. Hall Perform on stage at a well-tuned 2000-seat concert hall, all in the privacy of your own home. The Mix level lets you experience the space without getting lost in it. Arena Go big with the Adjust knob at maximum, and listen to the natural decay with no hint of graininess or flutter. Spring The Spring setting captures the attack, response and vibe of the best spring tanks found in amplifiers from the past and today. 8

9 Delay The Glass Nexus s Delay adds an extra dimension with the FILTER control, morphing smoothly from carbon-copy digital delay when minimum, to an analog-style delay (complete with added grunge) at 12:00 to a tape-style delay at maximum. Like the Reverb, the Delay effect is available at all times. Use the DELAY MIX knob to adjust wet/dry ratio. If you want to hear the delay without the modulation effects or reverb, just turn the EFFECT MIX and REVERB MIX to minimum. Tap Tempo In any effect mode, STEP AND HOLD DOWN while strumming or playing staccato notes to set the Delay Time. For more information, see the section on Strum Tempo. LED Indicators The Right Tube chamber indicates the delay status by flashing red (green in Bypass) at the delay time whenever the Delay Mix not set to dry. When the Delay Mix set dry, right chamber glows solid. Example Settings - The following settings highlight only the Delay effect, which occurs when you turn down the EFFECT MIX and REVERB MIX as shown in any of the Effect/Preset encoder positions. Slap Classic rockabilly slap echo is achieved with a short delay time, a single repeat, the proper filter shape, and a 50/50 mix. Clean This setting produces a warm a clean delay that will add some dimensional space to your sound. It ll work well for lead or rhythm parts. Analog With longer delay times, the bucket-brigade circuits in beloved stompbox delays exhibit a host of artifacts that include noise, distortion and even aliasing from low clock speeds. With the Filter knob at 12:00, the Glass Nexus recreates these effects for those times when your tone calls for some classic analog warmth. 9

10 Selectable Modulation Effects Glass Nexus s eight modulation effects are crafted to produce musical and wide-ranging sounds. As you turn the Effect Mix and Adjust knobs, each effect seamlessly revoices its parameters to give you an unprecedented combination of power and simplicity. PHASER The phaser is a classic effect that s heard on countless recordings. The Glass Nexus s phaser uses the EFFFECT MIX knob to control the phasing intensity. At settings less than 12:00, the phaser effect is mild but instantly recognizable. As you turn up the mix, the phaser becomes more pronounced and exaggerated while still retaining its classic character. At minimum MIX, the effect is off. The EFFECT ADJUST knob sets the LFO speed. LED Indicators When PHASER is selected, the Left Tube Chamber indicate the EFFECT MIX and ADJUST settings, changing from green to red at the LFO rate, with intensity determined by the MIX. The Right Tube chamber indicates the delay status by flashing red at the delay time whenever the Delay Mix not set to dry. When the Delay Mix set dry, right chamber glows solid. In Bypass, the Left Chamber flashes green at the LFO speed and intensity, and the Right Chamber flashes green at the Delay Time when Delay Mix is not dry. Tap Tempo Step on the TAP TEMPO button at the rate you want for the PHASER LFO speed (otherwise set by the EFFECT ADJUST knob). STEP AND HOLD DOWN while strumming or playing staccato notes to set the Delay Time. Example Settings Intense Slow Phase The phaser creates a dramatic slow-sweeping effect that goes great with rhythm and chordal work. The delay is set to add some analog-style repeats to create a vintage stomp-box sound. Classic Phaser Some mild phasing creates an effect suitable for lead or rhythm. Add some spring reverb to further fill out the sound. Wet Phaser At fast speeds, the phaser can take on a watery sonic character. Some room-sized reverb adds a nice finishing touch. 10

11 ROTARY The rotary speaker is a staple in blues and R&B music. Originally developed for the electric organ, guitarists soon realized that rotating speakers provided with them increased sonic dispersion and a great new sound. The Glass Nexus s rotary effect is highly detailed to immerse you in the swirling soundscape. EFFECT ADJUST controls the rotational speed, while EFFECT MIX varies the intensity from subdued to super-real. At minimum MIX, the effect is off. LED Indicators When ROTARY is selected, the Left Tube Chamber indicates the EFFECT MIX and ADJUST settings, changing from green to red at the LFO rate, with intensity determined by the MIX. The Right Tube Chamber flashes red to indicate the delay time if the DELAY effect is on (DELAY MIX not set to dry), and is solid red when DELAY MIX is set to dry. In Bypass, the Left Chamber flashes green at the LFO speed and intensity, and the Right Chamber flashes green at the Delay Time when Delay Mix is not dry. Tap Tempo The original rotary speaker systems had two speeds fast and slow. One of the cool features of these systems is their inability to change speeds instantaneously. In ROTARY mode, use the EFFECT ADJUST knob to set the fast speed. The TAP TEMPO footswitch will switch between this user-determined fast speed and the minimum speed with a ramp-time to create a realistic and natural effect. STEP AND HOLD DOWN while strumming or playing staccato notes to set the Delay Time. Example Settings Blues Room With full MIX, the ROTARY effect gives you a lively 3-D experience. Some ambient reverberation puts you in a venue where old velvet drapes keep the light out and the smell of smoke in. Pulsing This setting produces a beautiful hypnotic sound that is equally useful for chords or single notes. The spring reverb complements the vibe. 11

12 CHOIR The idea of a chorus effect is to turn a single instrument into an ensemble of instruments. The CHOIR effect in Glass Nexus allows you to add voices to create larger ensembles without experiencing the typical LFO warbling that occurs in conventional chorus algorithms. Use the EFFECT ADJUST to vary the number of voices in the choir. The EFFECT MIX varies the ratio of dry signal to wet signal. At minimum MIX, the effect is off. LED Indicators When CHOIR is selected, the Left Tube Chamber reflect the EFFECT MIX, changing from green to red as the mix is turned from minimum to maximum. The Right Tube Chamber flashes red to indicate the delay time if the DELAY effect is on (DELAY MIX not set to dry), and is solid red when DELAY MIX is set to dry. In Bypass, the Left Chamber is green, and the Right Chamber flashes green at the Delay Time when Delay Mix is not dry. Tap Tempo The TAP TEMPO will not alter the CHOIR effect. STEP AND HOLD DOWN while strumming or playing staccato notes to set the Delay Time. Example Settings Thick With lower ADJUST settings, the CHOIR effect will fatten up your signal and create a nice stereo image when using both outputs. Add some reverb to taste. Studio Processor The multi-voice CHOIR sets up a lush sound feeding the DELAY and REVERB. The Glass Nexus creates this huge sound with performance that rivals dedicated rack processors. 12

13 TREM The Tremolo effect was introduced in some of the earliest amplifiers and produces a pleasing cyclical variation in volume. One of the main differences among various tremolo circuits is the shape of the LFO waveform that controls the volume change. The Glass Nexus employs a sophisticated LFO that changes shape as the MIX (depth) and ADJUST (speed) controls are varied to allow for an optimized and musical effect at all speed and depth settings. At minimum MIX, the effect is off. LED Indicators When TREM is selected, the Left Tube Chamber indicates the EFFECT MIX and ADJUST settings, changing from green to red at the LFO rate, with intensity determined by the MIX. The Right Tube Chamber flashes red to indicate the delay time if the DELAY effect is on (DELAY MIX not set to dry), and is solid red when DELAY MIX is set to dry. In Bypass, the Left Chamber flashes green at the LFO speed and intensity, and the Right Chamber flashes green at the Delay Time when Delay Mix is not dry. Tap Tempo Step on the TAP TEMPO button at half the rate you want for the TREM LFO speed (otherwise set by the EFFECT ADJUST knob) and the TREM effect will pulse at twice the tapped speed. STEP AND HOLD DOWN while strumming or playing staccato notes to set the Delay Time. Example Settings Slow and Steady This setting works well for sustained chords. Use the Tap Tempo to set the ¼ note tempo of the LFO pulsations to match the tempo of your song,. Subtle This speed and depth setting showcases the pleasing, organic characteristics of the best tremolo circuits. This will sound great with either chords or single notes. Fast and Furious The first effects readily available to most early electric guitarists were the built in tremolo (erroneously called vibrato many times) and spring reverb in their amplifiers. Recapture the past, or make your own statement with Glass Nexus. 13

14 VIBE The original Univibe pedal attempted to recreate a rotating speaker effect with a specially designed phasing circuit. The result was one of the most identifiable guitar tones of the late 60 s and early 70 s, made famous by Jimi Hendrix and Robin Trower. The VIBE effect in Glass Nexus captures the pulsing and swooshing that makes the Univibe a highly sought after sound today. Control the speed with the EFFECT ADJUST knob, and the intensity with the EFFECT MIX knob. At minimum MIX, the effect is off. LED Indicators When VIBE is selected, the Left Tube Chamber indicates the EFFECT MIX and ADJUST settings, changing from green to red at the LFO rate, with intensity determined by the MIX. The Right Tube Chamber flashes red to indicate the delay time if the DELAY effect is on (DELAY MIX not set to dry), and is solid red when DELAY MIX is set to dry. In Bypass, the Left Chamber flashes green at the LFO speed and intensity, and the Right Chamber flashes green at the Delay Time when Delay Mix is not dry. Tap Tempo Step on the TAP TEMPO button at the rate you want for the VIBE LFO speed (otherwise set by the EFFECT ADJUST knob). STEP AND HOLD DOWN while strumming or playing staccato notes to set the Delay Time. Example Settings Undulating At moderately slow settings, the vibe creates a dramatic effect. This sounds great with single coil neck pickups. With distorted guitar tones, turn the MIX down to tame the extremes of the sweep. Faster The origins of this effect as a rotating speaker simulator become clear at faster settings, while providing its own distinct character. As always, some delay provides a bigger experience. Phasey The phaser aspect of the vibe effect is strong at the slowest speeds, creating a great slow-sweep phase that s voiced differently from the PHASER effect in Glass Nexus. 14

15 FLANGER Originally produced by mechanically varying the speed on one of two synchronized tape machines playing the same track, the flanger effect is best known for its dramatic rising and falling frequency enhancement. The Glass Nexus s FLANGER effect uses the EFFECT MIX to vary the intensity of the flanging from subtle shimmering sounds at low settings to intense jet-like sounds at high settings. At minimum MIX, the effect is off. The EFFECT ADJUST knob controls the LFO speed and some behind-the-scene parameters to make a super-versatile effect. LED Indicators When FLANGER is selected, the Left Tube Chamber indicates the EFFECT MIX and ADJUST settings, changing from green to red at the LFO rate, with intensity determined by the MIX. The Right Tube Chamber flashes red to indicate the delay time if the DELAY effect is on (DELAY MIX not set to dry), and is solid red when DELAY MIX is set to dry. In Bypass, the Left Chamber flashes green at the LFO speed and intensity, and the Right Chamber flashes green at the Delay Time when Delay Mix is not dry. Tap Tempo Step on the TAP TEMPO button at the rate you want for the FLANGER LFO speed (otherwise set by the EFFECT ADJUST knob). STEP AND HOLD DOWN while strumming or playing staccato notes to set the Delay Time. Example Settings Slow Sweep The FLANGER effect will sweep to a wide range of frequencies with high MIX settings. For clean tones this adds a nice enhancement that s particularly effective with chords, while distorted tones will get an intense jet-like effect. Chorus Hall This produces a mild flanging that is akin to a chorus effect. The reverb setting places you in a large performance hall to reverberate the flange. Trippy With the ADJUST control at higher settings, the flanger enters the realm of psychedelic. 15

16 VIBRATO The VIBRATO effect is created by a cyclical change in pitch, similar to the vibrato that occurs by rocking your finger back and forth when holding a note on the guitar. The Glass Nexus uses a custom LFO waveform to vary the pitch with maximum musicality. The Mix sets the depth of the vibrato, with no effect when MIX is at minimum. The ADJUST knob determines the speed of the LFO. LED Indicators When VIBRATO is selected, the Left Tube Chamber indicates the EFFECT MIX and ADJUST settings, changing from green to red at the LFO rate, with intensity determined by the MIX. The Right Tube Chamber flashes red to indicate the delay time if the DELAY effect is on (DELAY MIX not set to dry), and is solid red when DELAY MIX is set to dry. In Bypass, the Left Chamber flashes green at the LFO speed and intensity, and the Right Chamber flashes green at the Delay Time when Delay Mix is not dry. Tap Tempo Step on the TAP TEMPO button at the rate you want for the VIBRATO LFO speed (otherwise set by the EFFECT ADJUST knob). STEP AND HOLD DOWN while strumming or playing staccato notes to set the Delay Time. Example Settings Medium Not too fast, not too slow. Not too much, just enough. Perfect for chords or leads. Spinning The horn of a rotating speaker produces (among other things) a vibrato effect that s predominant when the horn is spinning quickly. You can isolate that effect by turning up the MIX and ADJUST to get a cool and useful effect on its own. 16

17 DETUNE The DETUNE effect changes the pitch of the signal by a constant amount (no LFO variation). In Glass Nexus, the shift amount has a range of +/-1/2 step, controlled by the EFFECT ADJUST knob. The EFFECT MIX controls the wet/dry mix, with no effect when the MIX is at minimum. LED Indicators When DETUNE is selected, the Left Tube Chamber reflect the EFFECT MIX, changing from green to red as the mix is turned from minimum to maximum. The Right Tube Chamber flashes red to indicate the delay time if the DELAY effect is on (DELAY MIX not set to dry), and is solid red when DELAY MIX is set to dry. In Bypass, the Left Chamber flashes green at the LFO speed and intensity, and the Right Chamber flashes green at the Delay Time when Delay Mix is not dry. Tap Tempo The TAP TEMPO will not alter the DETUNE effect. STEP AND HOLD DOWN while strumming or playing staccato notes to set the Delay Time. Example Settings Detune Chorus Adding the Dry signal with a slightly detuned version creates a fat chorus sound. Vary the adjust knob around 12:00 to get different flavors. Half Step Down Play along with your favorite guitarists who tune their guitars down a half-step. 17

18 Preset Operation The Glass Nexus can store eight presets (2 available in each of the four Preset Banks) without any external MIDI connection. With MIDI, you can store and recall hundreds of locations. See the section under MIDI for more information. Playing Presets With the encoder in one of the Preset Bank positions, the Glass Nexus can access two preset sounds (A or B) or be Bypassed, so you can set up a sound for rhythm and a different sound for lead for example, as well as bypass the effects altogether. The footswitch operation allows onestep access for all switching combinations. The following chart shows the LED indicator states during Preset playback: Left Tube Chamber(A) Right Tube Chamber(B) Magic Eye Preset A active RED GREEN RED Preset B active GREEN RED RED Bypass GREEN GREEN GREEN To activate a preset: 1. Turn the encoder to one of the Preset Banks 2. If one tube chamber is red, the corresponding preset is active. Stepping on the other footswitch will activate that preset directly. 3. If the unit is in BYPASS (all indicators green), step on either the A or B footswitch to activate the corresponding preset 4. Stepping on the active preset s footswitch again will put the unit in BYPASS 18

19 Saving Presets Once you have a sound that you want to save: 1. PUSH AND RELEASE the encoder knob. The Magic Eye will turn green and the tube chambers will turn orange to acknowledge the initiation of Preset Save. 2. Turn the Encoder to the Preset Position that you want to store it to. 3. To save the settings to A, step on the A footswitch. To save the settings to B, step on the B footswitch. The Magic Eye and tube chamber of the selected preset will turn red. If steps 2 and 3 aren t completed within 10 seconds of pushing the encoder knob, the process will abort and the Glass Nexus will resume operation based on the current positions of all parameter knobs and the Effect/Preset selector. Note: Once a preset is written to a location, the previous Preset at that location is lost. Editing Presets When playing a preset, all parameter knobs are available for adjustment. So if you are playing a preset and want to change the Delay Mix parameter, just turn the Delay Mix knob to the new desired value. All other parameters will remain unchanged, unless their corresponding knob is adjusted. If you like your adjustments and want to save the new sound, you simply save the new sound exactly as you would if you were writing a new preset. For example, you can overwrite the current preset by pushing the encoder and stepping on the same footswitch of the preset you started from. To write your edited preset to a new location without changing the original, push the encoder and then select the new location with the encoder and footswitches as described above. Note: Once a preset is written to a location, the previous Preset at that location is lost. Restoring Factory Presets Glass Nexus comes with eight factory presets that can be restored by the following procedure: 1. Disconnect the power adapter plug from the power jack 2. Press the encoder 3. Connect the power adapter plug to the power jack while continuing to press the encoder for 5 seconds. Note that this will overwrite all eight presets. MIDI presets from program change 9 and up will not be affected. See the section on MIDI for more information. 19

20 Delay/Reverb Persist Glass Nexus can continue to process the delay and reverb signal after you step on the Bypass switch, allowing for natural decay of the signal when the Glass Nexus is Bypassed. Effects Modes The state of Delay/Reverb Persist is global for the Effect selections, i.e. when Delay/Reverb Persist is activated in one of the eight Effect positions, it remains activated for all of the Effect positions. To activate Delay/Reverb Persist: (with the Mode Selector in any Effect position) 1. PUSH AND HOLD DOWN the Mode Selector while you PRESS AND RELEASE the ON/BYPASS footswitch 2. RELEASE the Mode Selector. To exit Delay/Reverb persist mode, follow the same procedure that was used to enter Delay/Reverb Persist mode.! Note: Glass Nexus will remember the most recent global state of Delay Persist upon power up. Presets In Preset operation, the Delay/Reverb Persist state is saved individually for each preset location, so you can save some presets with it on, and some with it off. To Save a new Preset (from one of the eight Effect Encoder positions) with Delay/Reverb Persist active: 1. Activate Delay Persist as described above 2. Save the preset as described under Saving Presets You can also change the Delay/Reverb Persist state of an existing preset. This has no effect on the global Delay/Reverb Persist state of the Effects Modes. To change the Delay/Reverb Persist state of an existing preset: 1. Set the Glass Nexus so the desired Preset is active (its Tube Chamber is Red) 2. PUSH AND HOLD DOWN the Mode Selector. 3. PRESS AND RELEASE the footswitch of the preset you are changing. 4. RELEASE the Mode Selector. At this point the preset will respond to the change in Delay/Reverb Persist when it is Bypassed, but the preset has not been saved with the change yet. If you access another preset or move the Encoder knob, the change will be lost. In order to save the Delay/Reverb Persist change, the preset needs to be saved as described under Editing Presets 20

21 Strum Tempo You can adjust the Delay Time based on strumming input from your guitar, giving you another way to take advantage of Glass Nexus s power in live situations. To set the Delay Time based on strum input: Tips 1. PRESS AND HOLD DOWN the TAP TEMPO footswitch. The Right Tube chamber will go dark. 2. Strum or pluck staccato notes at the Delay Time you desire. The Right Tube Chamber will flash red to acknowledge each input. 3. RELEASE the TAP TEMPO footswitch. Be precise with your playing when during strum tempo input. Try to leave space between the notes play staccato If you are playing with very high gain, or a very noisy guitar signal and the strums are not being recognized by Glass Nexus (Right Tube Chamber not flashing), try turning the down your guitar s volume control and trying again. 21

22 MIDI Glass Nexus allows access to 1280 presets, full remote control of all knobs and switches, and advanced control, such as individual effect ON/OFF and clock input. Glass Nexus responds to MIDI messages sent on MIDI Channel 2. Presets Presets are organized as 10 banks of 128 presets, for a total of 1280 presets. Glass Nexus will respond to standard MIDI Program Change Message. The default Bank is Bank 0 (when no MIDI Bank message is sent). Bank messages are sent with controller 00, with values ranging from 0 to 9. MIDI presets 1-8 correspond to the eight presets that are accessible from the top panel controls of Glass Nexus. Glass Nexus responds to messages sent on MIDI Channel 2. To write a preset to a MIDI location: 1. Set the knobs to get the sound you want 2. Press and release the encoder 3. Send a program change message on MIDI channel 2 to the MIDI location you want to save the settings to. For Locations greater than 128, send a Bank Message on Controller 00, followed by a program change message.! When Glass Nexus receives a Program Change message, the Footswitches act as if the unit is in Effects mode, i.e. you can Bypass Glass Nexus with the ON/BYPASS footswitch, and you can input tempo information with the TAP TEMPO footswitch when presets are selected through MIDI program change. Controlling Knob Parameters The following table shows the MIDI controllers that correspond to the knobs of Glass Nexus. Glass Nexus responds to messages sent on MIDI Channel 2.
