For best results when creating reverb effects, use a short buffer length and
shorter delay times with Delay 4.
Flanging and Chorus
The delay time can be modulated to produce flanging and chorus effects. The
main difference between the two is that flanging uses feedback and chorus
does not, and chorus typically uses a longer delay time (though, with modu-
lation, the range of delay times for each effect may actually overlap a bit).
For flanging, a Time value of 31 (4.8157 milliseconds) or less is a good
place to start. Use a triangle wave LFO to modulate the delay time, being
careful to keep the LFO Amount low so that it doesn’t drive the delay
time to zero and “flatten out” the triangle at one extreme. It will be fairly
obvious when that happens.
For chorus, start with a value around 53 (17.164 milliseconds).
Ping-Pong Echo
For ping-pong effects, use a square LFO routed to Delay Pan. Some
amount of DC routed to Delay Pan (in the modulation matrix) will place
the ping-pong in the desired position in the stereo field. Both the LFO
and the Delay must have Sync on, and the LFO should also have Wave
Reset on, to keep everything in sync.
