Vocal filter, sort of
Logorrhea is kind of a vocal filter; basically it is the back half of a vocoder crammed into 8HP. There are two inputs, 10 filter channels, a white noise channel and a thru channel, to feed thru the original signal(s). It uses two SSI2190 chips to do all the work.
There are no knobs, use a De-escalate if you need to attenuate your CVs.
To use, patch in one or two audio signals. Ones with lots of harmonics sound best, pulses, squares or wave-folder outputs, not sinewaves.
Patch in a bunch of CVs to set up your sounds, it expects 0-5V CV signals.
OUT is all channels mixed together.
OUT A is thru, LP (low pass), BP2, BP4, BP6 and BP8 (BP = bandpass).
OUT B is noise, BP1, BP3, BP5, BP7 and HP (high pass).
Using OUT A and OUT B in a stereo mixer (such as NLC Macramé) is nice with panning to move the sounds around.
These merchants probably sell this module. Huh?
