Internal Design of the DTX700  Chorus Chorus reproduces the sound of multiple instruments playing in unison for a thicker, deeper tone. As all instruments differ slightly from each other in terms of pitch and phase, their playing together produces an overall sound that is warmer and more spacious. In order to reproduce this type of behavior, chorus effects make use of delay. Specifically, a delayed, second version of the original signal is produced and given a vibrato-type effect by varying its delay time over a period of approximately one second using an LFO. When this second version is mixed back into the original signal, the resulting tone sounds as if multiple instruments are being played in unison. Effect Type G Chorus 2 Modulator SPX Chorus Symphonic Ensemble Var Cho Description   Rich, deep chorus with complex modulation. Chorus effect allowing pitch and   amplitude modulation to be adjusted for a more natural, spacious tone.   Enhances modulation and spaciousness using a 3-phase LFO.   Multi-stage modulation for a widersounding chorus. -  Modulation-free chorus achieved by adding a slightly pitch-shifted sound.  Tremolo & Rotary Tremolo effects are characterized by the way in which they modulate volume in a cyclical fashion. An auto-pan effect, meanwhile, moves the sound from left to right in a similar cyclical manner, and a rotary speaker effect simulates the distinctive vibrato of rotary-type speakers often used with organs. In a rotary speaker, the horn and rotor are spun in order to create highly unique sounds using the Doppler Effect. Effect Type AutoPan Tremolo RotarySp Var Description  Cyclically moves the sound between left and right channels.  Cyclically modulates the volume of the processed signal.  Rotary speaker simulator.  Delay Delay effects create a delayed version of the input signal, and as such, they can be used for many different purposes, such as creating a sense of spaciousness or thickening a sound. Effect Type CrossDelay TempoCrosDly TempoDlyMono TempoDlySt Delay LR Delay LCR Delay LR St Var Description A pair of delays featuring cross-over feed back to produce a sound that swirls between the left and right channels.  A pair of delays with cross-over feedback and a tempo-synchronized delay time.  A single mono delay synchronized with the instrument's tempo.  A stereo delay synchronized with the instrument's tempo.  A delay with separate left and right channels.  A triple delay processing left, right, and center channels independently.  A stereo delay with fully independent left and right channels.  Miscellaneous This category contains effect types not included in the other categories.
