Circuit bent Autogenic Systems biofeedback units: AT32 TEMP & AT64 SCR
°
These were fun. 
I added optical control and human contact to both, and CV input on the AT64. The AT32’s biofeedback input is a minijack which unwillingly but graciously accepted CV in—definitely not up to spec.

These are both nice and expressive devices via their biofeedback leads, especially the AT64. With the conductive leads attached to two fingers on one hand, I can create something like slow evolving aleatoric 10-note lo-fi piano music.

The optical control adds a bit of odd trigger sequencing to the mix.
The AT32 has a more percussive sound selection, whereas the AT64 tends toward the oscillator/simulated piano set.

By touching each gadgets’ human contact resistance discs simultaneously each devices’ current flows through me and into each other, sometimes crashing one, sometimes creating weird distortion and detunings depending on how much surface area of my hands I apply to the silver discs.

I built these for "uB Radio Salon 831: The 4th Sunday Players' Bonus 3rd Sunday!: Simultaneous Semi-Super-Group" show near the end of December 2023. Link in my tree below.
They are being sent through a Space Echo RE-201 tape delay.
