Yet another in this series of mine. It's fun to stop the video in random places to try to see the 'faces' of the 'spirits'! ;-)
Technical details: AUDIO - this is a mostly self playing modular synthesizer patch. All four outputs of a Modcan 66B feed two Modcan 55B dual quantizers which control the pitch of four Synth Tech MOTM-300 VCOs. Each of the four voices are completed with a MOTM-800 EG and a MOTM-190 VCA. The master clock is a Modcan 53B which feeds a Moon Modular M554 Octal Clock Divider. The M554, via a M591 quad switch, provides gates for both the voice EGs and 55B sections. Also the 554 provides a long clock cycle that resets the 55Bs. A Strymon BigSky reverb pedal is the only effect used (no reverb added in post). The audio (pre-reverb) is connected to a small oscilloscope so what you see is a representation of what you hear.
