[sdiy] [AH] Arp Solina with excessive chorus noise

[Richie Burnett]

You could use an outboard hardware or VST plug-in noise gate, if the instrument's built-in chorus is special, or...

Keep the on-board Chorus switched off to keep the noise down, and process it with outboard digital chorus, or VST effect on your computer.

Recapping the supply decoupling capacitors in the chorus circuit sounds like an excellent idea to me. It is exactly high ESR in decoupling capacitors here that can let HF ripple from one BBD clock get into the other BBD circuits and cause that horrible aliasing swooshing noise you get when two changing frequencies beat together.

-Richie,

>> It's in pretty good condition, every function works and it sounds great, but there is, in my opinion, excessive noise and 'swooshing' when the chorus/modulation circuit is engaged.
