Sorry to interfere, but do you know if there is an equivalent of IG00159 (envelope IC) or how to find one?

Thanks in advance!

Hi list,

A client of mine has a CS30 with a dead LFO chip.

It seems pretty well unobtainable, but my question is this.

Was it a chip rebadged by Yamaha (ie a 566 or a 4151) or has anyone produced a module to emulate it?

All the best

John
