"One of the two interchangable filters for my next project! This is a tightly match transistor ladder, low pass filter! In the background- the 6 Oscillator board- keyboard and other stuff!"
Note this is a filter for the touch keyboard and not a stand alone module.
On the keyboard:
"6 Oscillators- 4 as audio- with x-mod capabilities- 2 as modulators/audio oscs. All voltage controlled. There are two traditional MC1496 ring modulators and a twin noise generator. All sounding right just now!"
