ivo is a resonant low-pass vcf (voltage controlled filter), switchable between 2-pole (12db/octave) and 3-pole (18db/octave) responses, with voltage control over feedback (resonance) as well as cutoff frequency. it will self-oscillate in
2-pole mode.
the module has two audio inputs, one with an attenuator, so it will also mix two signals at the filter input.
the module is 100% analogue, using discrete transistor otas.
specifications:
panel width: 8hp
module depth: 37mm
current draw: 22ma on the +12v rail, 18ma on the -12v rail
