DSP Type List (PSR-640)
DSPType
System/Insertion
Description
Hall1-5
System
Concert hall reverb.
Room1-7
System
Small room reverb.
Stage1-4
System
Reverb for solo instruments.
Plate1-3
System
Simulated steel plate reverb.
Delay Left - Center -
System
Three independent delays, for the left, right and center stereo positions.
Right1, 2
Delay Left - Right
System
Initial delay for each stereo channel, and two separate feedback delays.
Echo
System
Stereo delay, with independent feedback level settings for each channel.
Cross Delay
System
Complex effect that sends the delayed repeats “bouncing” between the left and right channels.
ER1, 2
System
This effect isolates only the early reflection components of the reverb.
Gate Reverb
System
Gated reverb effect, in which the reverberation is quickly cut off for special effects.
Reverse Gate
System
Similar to Gate Reverb, but with a reverse increase in reverb.
Karaoke1-3
System
A delay with feedback of the same types as used for karaoke reverb.
