"This is a VCS3 solo, processed by a resonator. The resonating overtones are entered by a midi keyboard. The VCS3 oscillators slide past the chosen overtones producing a violin sound. The Putney's oscillators are controlling each other as osc.3 sends osc.1&2 sliding up & down in opposite directions (thanks to splitting osc3's CV out to the oscilliscope & back in again) ... all live... all VCS3"
