In case anyone is interested, this is the heart of the digital (current) version of the CH-1:

Hi Laurie

Thanks, added this to the Library.

I See it's related to the PT239x series of Delay chips,
used on a lot of consumer, DVD players, home LoFi stereo's & Karaoke gear.

I would like to see the sch. & service notes for this version of the CH-1, they must be doing something like sweeping the clock inputs, with a triangular waveform to get the chorus effect.

Regards Dr. Bob

This datasheet is full of typos, hopefully, the chip contains less errors.
