Troubleshoot info:
"did the RTFM-thingy on Ken's website and connected the frequency pot to +VE / -VE and added a 150K restistor in series ... as mention on the website " found on electromusic.com
What connection would you make to the ccw position of the potentiometer in place of gnd to wire it between +/-V?
If you mean "how do you wire the frequency pot so that it gives a wider range, going lower than the frequency obtainable with the CCW end of the pot wired to earth", the answer is you wire it to -VE. If that gives you too much range, put a resistor between the CCW end and the -VE rail. 47k would be a good starting point.
Technical:
Controls:
- Frequency - sets intial filter frequency
- Freq CV 1- Attenuator for CV in 1
- Resonance - controls amount of filter resonance
- Distortion - Mixes in post filter distortion effect
- Filter Mode - selects lowpass, bandpass, highpass and notch modes
I/O:
- In - audio input to filter
- CV 1 input - filter frequency input with attenuator
- CV 2 input - filter frequency input
- Out - filter output
