So, i had a look at this example.... There are seperate messages for note on and off, and i think the last value in the message must be decay, but it seems not to work... Or where do i go wrong here?

Yes, i know, it's boring, but not for me, i have such a great patch, the only thing that really disturbs me are envelopes, i can't tell you how hard i try to get rid of these clicks in the sampleplayer, again and again, it's awful
