Hi, it's me again.

Just noticed one of my M boards has a small issue in that the filter doesn't seem to be responding to the filter envelope and also it seems generally more 'closed' than the others.

I am assuming on listening to it, that it just goes straight to where the others 'end up' according to the filter envelope settings but even then it seems more 'muted' than the other notes.

I have changed both filter chips/IG00156 but no difference.

Since IC12 (the IG00152) is soldered in place I'd like to be certain of the problem before removing anything.

Does anyone have any ideas please?

Cheers,
TOM
