hey that's not so dumb...that sounds like a smart analysis to me.
I'm at work so I can't attempt to reproduce it, but to fix the
problem, I would guess you need to generate the note off somehow...
like I wonder if a note off is generated when you press stop?

I wonder if the sequencer SHOULD generate a note off.   in an ideal
world, the note off from the note one should be sent as soon as the
LEN parameter is reached....but all bets are off when you switch to
a new drum kit and the the old machine no longer exists!  

so you could either, let those machines hang around a bit longer before
disappearing, but this would consume resources and screw everything
up (say you rapidly swtich through several patterns with 16 midi machines!)
.....or you could simply make a decision to send note offs when you
uninstantiate a midi machine...

wish I could remember all those params for you on the midi machine...

try this though for a cheap thrill- connect two (random) LFO's to a
midi machine, one to controller number and one to controller value
and plug it into e.g. your sid station!  it's crazy, man!
