Resonate
Four-band vactrol resonator after the Korg PS-3100
Panel · 40.6 × 128.5 mm
Description
The core of the Korg PS-3100's resonator, with RJB's 2005 mods, grown to four voltage-controlled band-pass stages and given a feedback control. Its CV processing is simplified to op amps driving the vactrols.
Key features
- Four band-pass stages, FREQ1 to FREQ4, each with its CV input CV1 to CV4
- CV1, through its CV1 (ALL) knob, moves all four stages
- Q, the feedback
- Two inputs, summed; OUT2 is OUT1 inverted
- 8 HP; current draw as ModularGrid lists it (Nonlinearcircuits publishes no current draw, depth or assembled price: it sells the DIY PCB and panel)
