Hi, I'm returning to this topic as I was busy with other stuff for a while.=
..

Anyways, I think the Sust II on my Yamaha CS40M isn't working
correctly - I mean Sust II doesn't really cut off the release of the
previous sound. I mean let's say I have a single oscillator sound and
I first play the note D3 (with long release) and release the D3 and
the depress E3, for a moment I hear two oscillators playing E3 and the
other one fades according to the release time. That's kinda weird -
shouldn't the new note cut off the previous one entirely?
