Hopefully this block diagram can help explain somewhat.
Input Preamp - clean with gain up to 20dB
Two independent or chained 12dB/Oct State Variable Filters with resonance (Q) to self-oscillation.
Each filter covers the full audio spectrum 20-20kHz and has Low/Band/High-pass outputs though not all of these are accessible on the standalone module (there is a 1FW expander for modular users which presents ALL + extra CV and audio ins)
The filters can be run in Series or Parallel:
Series - the High output of Filt1 feeds the input of Filt2.
Parallel - both filters get the buffered input signal. In this mode the first filter is purely a Low-Pass, while the 2nd has separate Low/High outputs.
I was initially just going to have Series but it proved easy to add the mode switch.
The Filters are, of course, voltage controlled, scaled to 1V/Oct (haven't confirmed tracking range - imagine 5+ octaves tight tracking) - each one has an FM input (banana) and polarizing depth control. The Int/Ext switches are a weird bonus -> I took the BandPass output from each filter and that feeds the Int switch position for some audio cross-modulation - it can get very gnarly and chaotic, especially with high resonance.
The three outputs bands each have a polarity switch (centre-off for quick signal muting) so you can experiment with phase inversion/cancelling before an output level control and buffer.
The Low and Mid outputs are normalised to the High section so if nothing is plugged into either then the signal flows on to mix at High.
I found this quite powerful - you can either mix in mono from the High output, adjusting the different bands OR perhaps take each output to a different mixer channel & try panning (headphone space out). I'd been keen to start bringing some more stereo action to my setups and while this is obviously just MONO in, the 3 outputs gives some new fun powers.
Release date & price TBC - as mentioned, production is underway, but this always takes some time.
Too promising design, I have to save some money!
