Basic reverb / allpass
Posted: Mon Oct 24, 2011 3:33 am
Hi, I'm confused as how to implement a basic reverb on the fv-1.
I want to be able to scale the reverb room size (the allpass delay times) using one of the potentiometers...
The allpass type I want to use is this:
But another strange thing is... I'm having a hard time wrapping my head around the actual sequence, should it be basically:
get input and write it to tap delay reg
get feedback taps and write into acc
add allpass ring feedback into acc
allpass acc (coef1)
allpass acc (coef2)
allpass acc (coef3)
write acc to ouput
lowpass + highpass acc
write acc to allpass ring feedback
I want to use a multi-phase lfo for modulation of the allpass delay times also, can I use the ramp lfo's add the phase offsets and wrap them within pi and then shape them into triangles and then using log to make some kind of pseudo sine shape?
