Forbidden Frequencies
A Krell derived patch.
Notes:
Set MIDI LFO to random notes. Then slew it to create a fluctuating random signal.
The S&H is attenuated with the Mixuverter to reduce high notes.
If the patch is too random try either quantizing the S&H output to a scale, or sending the S&H to control a sequencer that uses voltage to address stage selection.
