Make Noise Echophon

The Echophon, from Make Noise, is a Pitch Shifting Delay/Echo module. It is another module that was coded by Tom Erbe of Soundhack. It has smooth pitch shifting, as well as reverse delay for all classic tape-like delay effects. It has patch points for the feedback output and feedback input, allowing more FX processors to be patched between the feedback, creating all sorts of esoteric delay effects. A Freeze button and Gate input holds that millisecond of audio until pressed again. There are also clock inputs and outputs for synchronizing the delay time, or synchronizing other units to the Echophon. Like with all Make Noise modules, every parameter is Voltage Controlled.

The Echophon is usually used for pitch-shifting and delay, but it is open-ended enough to be useful for a number of other time based effects. Thanx Tom Erbe ( and Michael Hetrick ( for patch ideas.
