"Very Short" is the delay for a very short period of time (0.5 msec - 50 msec). The feedback gain is between -0.98 and +0.98.
This type of delay works as "comb filter", which adds some metallic noise to the input source.
Runs on prologue, minilogue xd, NTS-1, NTS1 mkII, and drumlogue. (The source code for drumlogue and NTS-1 mkII are on separate branches.)
