In this video we explore how to ping the filters of Spectravox to turn it into an analog physical modeling instrument and create percussive wooden sounds like marimbas or xylophones.
By replacing the carrier input to Spectravox’s filter bank with a gate or envelope instead of audio and turning the resonance of the filter up, we can ping all ten filters and mix their levels for creating struck percussion sounds. In this video we first turn the VCA mode ON and then patch the Gate output of Grandmother to the Trigger input of Spectravox to use Grandmother to trigger Spectravox’s envelope generator. Patching the EG output to the Program input gives us level control of the envelope, and finally patching the Program output to the Carrier input inserts our decay-only envelope directly into the audio input of the filter bank. Later, we connect the Keyboard CV output of Grandmother to the Shift CV input on Spectravox to move all ten filters for melodic control of the filter bank.
