Well vibrato is just chorus with the dry signal cut, so i feel it might be redundant. Im not sure about the low pass filter on just the noise, i think the lowpass should be on the whole signal.
as of right now I have things going like Input-->compressor-->random vibrato-->bit crusher-->HPF-->noise generator-->LPF-->compressor-->output
the way the HPF and LPF play with eachother does a really good job at covering alot of ground.
that being said - nothing is set in stone, and since the hardware design is done, theres only code to work out. so these are all just preliminary ideas subject to change. your advice is appreciated, keep it coming. i wont be able to properly test things until later this month so as of right now im just running things through a simulator.
