Subject: Crow's replacement M-boardRe: [yamahacs80] Re: Did any of your CS80 *restorations* involve new IC's...?

Hi Scott.

It's good to know you're still working on this! Any plans for
additional features beyond the original M-Board? I'd really like to see
a Moog-ladder filter on board. This is one really nice feature of
Arturia's VST. Also, two, tunable VCOs per board would be great. It
would let you have much more flexibility than the fixed tunings of the
Feet selectors and give a massive four VCOs per note!
