makes Polyphrase capable of achieving similar timbre to the storied analog,
bucket-brigade delays.

The echo signal can be pitch modulated with the

rate

and

depth

controls for a sine wave

style chorus / vibrato, or with a random wave for detuning effects similar to aging tape
echos.

Finally, Polyphrase has a fully featured

midi input

that provides tempo sync, full remote

control of all parameters on the faceplate, and access to 9 onboard user preset slots.

Infinite feedback

External feedback path

Tone control in the feedback path

Echo pitch modulation with sine or random style waveform
