Hi, This is a follow on from my attempt to sort out the 'd' score statement yesterday. I've simplified things by just seeing how held notes behave, and I'm still confused! Using a simple sine generator (CSD attached), I start with a score like this (p4=MIDI number, p5=amp): f0 z i1 0 -1 60 1.0 i1 1 -1 67 1.0 And I get what I'd expect -- the 'C' note plays for one second and is replaced by thw 'G', which plays until the csd is stopped. Then I remove the 'f0 z'. Now the C plays as before, but everything quits after one second and the G never sounds! In most situations these days I don't use 'f0' because a score usually plays to the end, and a totally empty score section stays active until killed. Is the above expected behaviour, or is it just a bug?
