Patch-chart 17 — External Signal Network

An instrument driven by an outside sound: plug a microphone or another source into AUX IN and set the preamp GAIN for it (the chart says "set accordingly"). The envelope detector's ENV OUT moves the pulser's period and the modulation oscillator's frequency; the modulation oscillator's MOD CV OUT drives gate 2's level. The sequencer moves the complex oscillator's timbre, a random voltage its pitch, and the envelope generator, triggered by the sequencer, opens gate 1. The chart leaves the five sequencer levels, the STAGES and PULSE SEQUENCE switches free: set them by ear. No keyboard needed.
