User manual ALESIS QUADRASYNTH SUPPLEMENTARY GUIDE

[. . . ] but is also right at home in the studio for processing vocals, drums, pianos, synthesizers (try the rotating speaker sound!), tape tracks, and other instruments. The QuadraVerb GT can insert between your guitar and subsequent effects units or amplification systems. This lets you use the amp's overdrive options to further color the QuadraVerb GT's sound. 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. [. . . ] As mentioned under Delay Type, the maximum delay depends on the selected reverb type and the configuration. 45 Delay Feedback (configs 1, 2, 3, 4, 6, 7) With Mono or Ping Pong selected for delay type, the display shows: DELAY FEEDBACK: 33% With Stereo selected, this will say DELAY FEEDBACK LEFT. Increasing the feedback increases the number of successive echoes; each echo will be softer than its predecessor. Right Delay Time (configs 1, 2, 3, 4, 6, 7) This page appears only if Stereo is selected as the delay type, and says: RIGHT DELAY TIME: 400 milliseconds This sets the time between successive delay signals, and is variable in 1 ms increments from 1 millisecond to the maximum delay available in the configuration. As mentioned under Delay Type, the maximum delay depends on the selected delay type and the configuration. Delay Feedback Right (configs 1, 2, 3, 4, 6, 7) This page appears only if Stereo is selected as the delay type, and says: DELAY FEEDBACK RIGHT: 33% Increasing the feedback increases the number of successive echoes; each echo will be softer than its predecessor. 46 Multi Tap Number (config 4 only) The display says: TAP NUMBER: 8 This parameter selects the tap to be edited on subsequent pages. IMPORTANT: When the Delay Time, Volume, Panning, or Feedback pages are selected, you can select the next higher-numbered tap by pressing the DELAY button. Going past 8 returns you to 1. Multi Tap Delay Time (config 4 only) The display says: TAP X DELAY TIME 0125 millisecs X is the number of the tap selected for editing. Example: If tap 1 is 150 ms and you want tap 2 to be 300 ms and tap 3 to be 400 ms, set tap 2s delay time to 150 ms (150+150=300) and tap 3s delay time to 100 (150+150+100=400). If you change a taps delay time, all higher numbered taps will be offset by the same amount that you changed the taps delay time. Multi Tap Volume (config 4 only) The display says: TAP X VOLUME: 50 X is the number of the tap selected for editing. This sets the volume of the selected tap. 47 Multi Tap Panning (config 4 only) The display says: TAP X PANNING: LEFT 00 RIGHT X is the number of the tap selected for editing. This pans the tap output anywhere in the stereo field between full left (99) and full right (99). Center is 00. Multi Tap Feedback (config 4 only) The display says: TAP X FEEDBACK: 00% X is the number of the tap selected for editing. Increasing the feedback increases the number of successive echoes this tap will produce; each echo will be softer than its predecessor. Multi Tap Master Feedback (config 4 only) The display says: MASTER FEEDBACK: 00% This scales all feedback parameters simultaneously if you want to increase or decrease feedback without having to readjust each taps feedback parameter. 48 4. 6 EDITING PITCH PARAMETERS Configurations 1, 2, 4, 5, and 6 can access the pitch parameters. Turn this parameter off to slow the speakers down to a stop, or on to speed them up to the speed set on the next page; its a natural for MIDI control (sections 6. 1-6. 2). Lezlie Speed (config 2 only) The display says: LEZLIE SPEED: FAST Mechanical rotating speaker systems generally offer two speeds, slow and fast. The QuadraVerbs simulated rotating speaker gives you two speeds also. Ring Modulator Spectrum Shift (config 6 only) The display says: SPECTRUM SHIFT: 100Hz This determines how much the up and down harmonic signals will be shifted with respect to the original input signal. Ring Modulator Output Mix (config 6 only) The display says: RING MOD. OUTPUT MIX: DOWN 00UP This varies the balance between the up and down signals. (With the QuadraVerb GT, excessive downshifting will not wear out the clutch. There is no clutch. ) Ring Modulator Delay/Reverb Input (config 6 only) The display says: DEL/REVERB INPUT MIX: DOWN 00UP The ring modulator signal that can optionally feed the Delay and/or Reverb inputs can consist of any blend of the up and downshifted signals. At 99, the output consists entirely of the downshifted signal. Reverb Chorus Mode (config 5 only) The display says: REVERB CHORUS: ON Don't confuse this parameter with the Chorus found in the Pitch module. Turning on the Reverb Chorus will make the reverb modulate and sound "swimmy". 54 4. 7 A WORD ABOUT EQ, RESONATORS, AND GUITAR TONE Resonators, EQ, and Tone A guitar tone is a complex thing. Factors as diverse as the wood, size, and shape of a guitar can alter its tone. Strings, pickups, hardware, active electronics, and a myriad of other factors make up the distinctive and elusive intangible known as "tone". All of these factors, however, have one thing in common: they alter the harmonic structure of the guitar's sound. While the fundamental frequency of A above middle C is 440 Hz, the timbre of the note itself is made up of not only the fundamental frequency, but a series of overtones (harmonics) as well. [. . . ] Like many other affordable keyboards, the DPM 2 does not include pressure. Program Change Sending a program change command from a sequencer or other MIDI keyboard can change synth patches automatically. Some number them as 000-127, others as 001-128, and still others arrange programs in banks of 8 programs (such as A1-A8, B1-B8, C1-C8, etc. ). Continuous Controller Footpedals, breath controllers, and modulation wheels can vary sounds as you play, thus adding expressiveness. [. . . ]
