QuadraVerb GT's sound. Or, patch the QuadraVerb GT into an ampÕs effects loop. This lets the QuadraVerb GT process the amp's internal sound, and in some cases, lets you use the amplifier's preamp section as an alternate to the QuadraVerb GT's internal preamp. -
Page 11: Ac Transformer Hookup
AC Transformer Hookup Plug the QuadraVerb GT's AC adapter into the wall. The smaller plug inserts into the 9 VAC power jack on the QuadraVerb GT's rear panel. To prolong the AC adapter's life, unplug it from AC power when not in use (turning off the QuadraVerb GT's power switch does not disconnect the AC adapter from AC power). -

Page 15: Interfacing With Mixer Stereo Effects Sends
Hookup Patch the mixer's auxiliary bus (or effects bus) sends into the right and left QuadraVerb GT inputs, and patch the QuadraVerb GT's right and left outputs to the mixer's stereo returns or if not available, two standard mixer channel inputs. -
Page 16: External Effects Hookup
5.7. 1.5 EXTERNAL EFFECTS HOOKUP The QuadraVerb GT offers an effects loop where you can patch in effects other than the ones included in the unit (you might want to insert, for example, a wah-wah pedal or vintage fuzz). -
Page 17: Setting Levels
After hooking up your cables, set the proper levels. Start off with your amplifier turned down to a low volume to prevent any ear-shattering surprises as you learn about the QuadraVerb GT. After you know what you're doing, increase the level to normal monitoring levels. -
Page 18: Selecting Programs
MIDI works. The most popular MIDI applications are hooking up a MIDI footswitch to change programs, and/or a MIDI continuous controller pedal to vary QuadraVerb GT parameters in real time, as you play. The following sections describe how this process works. -
Page 19: Midi Program Selection
¥ Other effects boxes If you use more than one effects box, calling up a program on it will often send a corresponding program change through its MIDI Out. NOTE: Your QuadraVerb GT and the MIDI footswitch must both be set to the same MIDI channel to execute program changes. MIDI In... -
Page 20: Midi Controller Pedal Hookup
(e.g., Anatek Pocket Pedal). Synthesizers and other devices also generate MIDI continuous controller data. If you want to feed the QuadraVerb GT with both a footswitch for program change control and a pedal for real time control, either the footswitch or pedal will need a merging input, or you will need a MIDI merger. -

Page 22: Chapter 2 Ð Quadraverb Gt Modules And Configurations
Many guitarists will find that the 90 factory presets take care of most, if not all, of their musical needs. However, the QuadraVerb GT is a very flexible device and comes into its own when edited to your own specific needs. -
Page 23: Delay
¥ Mono Delay Because this is a single delay line, it has twice the maximum delay time of the stereo delay (up to 1500 ms). ¥ Multitap Delay Available only in the 5 BAND EQ > PITCH > DELAY configuration, this delay includes 8 taps with variable delay time, volume, panning, and feedback amount for each tap. -
Page 24: Equalization
1960s. Equalization Equalization provides control over the tone of your signal by altering the frequency response in various ways. The QuadraVerb GT's three different types of EQ are: ¥ 3 Band Parametric This combines high and low frequency shelving equalizers (like the tone controls found on stereo systems and guitar amps) along with a sweepable midrange parametric stage (see Ó5 Band... - Page 25 The middle band is parametric and offers amplitude, frequency, and bandwidth parameters as described next. ¥ 5 Band Parametric This is identical to the 3 Band Parametric but offers two additional sweepable midrange stages with variable boost or cut, frequency, and bandwidth. The following diagram shows the relationship between three parameters.

Page 26: Panning And Tremolo
Sampling Sampling is the process of digitally recording a signal into the QuadraVerb GT's memory, which can then be triggered via an external audio input (e.g., a snare drum sound coming from a tape track), a front panel button, or a MIDI note. Different MIDI notes will transpose the sample. -
Page 27: Modulation
ÒBi-TimbralÓ Effects The QuadraVerb GT can serve as two separate effects units by proper patching to and from the effects loop. For example, consider a situation where a guitarist plays guitar and sings. Plug the guitar into the QuadraVerb input;... -
Page 28: About Configurations
to Amplifier From guitar Right Input 2.2 ABOUT CONFIGURATIONS No matter which program you select, the analog effects are always in the same order. However, the digital effects can be connected together in one of eight different ways, each of which is called a configuration. A configuration doesn't just include a specific collection of effects, but also the way in which they interconnect (e.g., whether the delay signal is derived from an equalized or non-equalized signal). -
Page 29: Preamp > Eq > Tremolo/Panning > Pitch > Delay > Reverb
#1 Preamp > EQ > Tremolo/Panning > Pitch > Delay > Reverb Pitch Input INPUT PREAMP Preamp Pre/Post EQ QuadModeª is a complex configuration that offers comprehensive switching and mixing possibilities. ItÕs excellent for creating larger-than- life, animated sounds. The Pitch module can switch its input between the preamp or EQ signals. -
Page 30: Preamp > Lezlie > Delay > Reverb
#2 Preamp > Lezlie > Delay > Reverb INPUT PREAMP This is similar to the QuadModeª configuration, but replaces the EQ and Pitch modules with a Lezlie (rotating speaker simulator) module and does not have a Preamp level control. The Lezlie module simulates the common two-speaker system with two different speeds. -
Page 31: Preamp > 5 Band Eq > Tremolo/Panning
This combines the 11 band graphic EQ with delay. The EQ provides sophisticated sound-shaping for the preamp sound, and the delay adds ambience for lead effects. #4 Preamp > 5 Band EQ > Tremolo/Panning > Pitch Change > Delay Configuration 4... -
Page 32: Preamp > 3 Band Eq > Reverb
INPUT This is the recommended configuration when you want the best possible reverb sound. By restricting the number of effects, the QuadraVerb GT can devote its full computing power to creating awesome reverberation effects. However, EQ is still available for additional tone shaping, as is a simpler version of chorusing. -
Page 33: Preamp > Ring Modulator > Delay > Reverb
#6 Preamp > Ring Modulator > Delay > Reverb Configuration 6 INPUT PREAMP This configuration features the Ring Modulation in conjunction with Delay and Reverb. The Ring Modulator is not available in other configurations. The Ring Modulator produces two outputs, both of which are mathematically derived (sum and difference frequencies) from the input signal. -

Page 35: Chapter 3 - Basic Editing Techniques
CHAPTER 3 - BASIC EDITING TECHNIQUES Editing is the key to using the QuadraVerb GT to its fullest potential. If you like a sound but want more reverb, less treble, more distortion, or whatever, editing is the answer. Make sure that if you develop a custom set of programs, that you save your data to some form of MIDI system exclusive storage device, like the Alesis DataDisk (see sections 5.5-5.6). - Page 36 QuadraVerb GT's MIDI modulation parameters. (See section 3.4) 3. Change the Parameter's Value A parameter's value is like the Òcalibration scaleÓ a knob would point to on a regular guitar effects box, except instead of setting a physical device to a certain position, you see the parameter setting on the screen and adjust its value with a pair of buttons (increase/decrease value).

Page 37: Comparing Edited And Non-Edited Versions Of Programs
3.2 COMPARING EDITED AND NON-EDITED VERSIONS OF PROGRAMS Editing a program does not change the original version permanently until it is stored (see section 3.3 below). Because your edited version is separate from the original, you can compare the two versions without altering the original. -

Page 97: Chapter 5 Ð Sampling
CHAPTER 5 Ð SAMPLING The QuadraVerb GT can record an audio sample of up to 1.55 seconds. During playback, the sample start and length times can be altered for special effects or to trim the playback of the sample to the actual start point of the sound. The sample can also be played back in its entirety (one shot) or continuously repeated (looping). -

¥ Off The QuadraVerb GT will not respond to MIDI note on/off information). ¥ MIDI One Shot The recorded sample will play back to the selected end of the sample, regardless of how long the key is pressed. IMPORTANT: If the playback mode is set to "Looping" and MIDI Trigger is set to One Shot, the sample will play indefinitely until the mode is changed or the sampling configuration is deselected. -
Page 103: Adjusting The Sample Playback Length
Notes ¥ Because of the nature of sampling, the timing of the sample as well as the pitch will change the farther away from the base note from which it is transposed, with the higher notes sounding like ÒmunchkinsÓ and the lower notes like Ògiants.Ó This is a normal phenomena that occurs during sample playback. -

Page 112: About Mod Sources And Targets
7.1 ABOUT MOD SOURCES AND TARGETS A mod source controls a particular QuadraVerb GT parameter. The QuadraVerb GT can respond to any of the following sources of data: ¥ Continuous controllers This is the type of data produced by MIDI Continuous Controller footpedals. -
Page 113: Programming Mod Sources And Targets
The basic idea is to choose a target parameter to be controlled, then assign a mod source to it (e.g., control delay feedback with controller 12). The QuadraVerb GT also lets you scale the amplitude and direction of the control data. In other words, increasing a controller value can either increase (positive direction) or decrease (negative direction) the target parameterÕs value;... - Page 114 3. Press the PAGE UP button again, and the display shows: MOD 1 TARGET: L FO SPEED Of course, your actual screen may show a different target parameter. 4. Choose the first target parameter with the VALUE buttons. Different configurations offer different target parameters for modulation; see the list at the end of this section.

Now, step on the pedal until it is all the way forward. Set the Mod Amplitude level to its maximum value (+99). This sets the amount of Reverb Output level you will hear when the pedal is completely forward. By assigning these two values to the extreme positions of your controller's range, you have defined the range within your target parameter that you will be able to modulate with the controller. -
