Description

A vocal filter: the back half of a vocoder in 8 HP, on two SSI2190 chips, with no knob. Two audio inputs, rich in harmonics (pulses, squares, folded waves), go through ten filter channels (LP, BP1 to BP8, HP), a white-noise channel and a thru channel, each level set by a 0-5 V CV. OUT mixes all; OUT A carries thru, LP, BP2, BP4, BP6 and BP8, OUT B noise, BP1, BP3, BP5, BP7 and HP, for panning in stereo.

Key features

  • IN1 and IN2 audio in; CV in for LP, BP1 to BP8, HP, NOIZ and THRU
