I would like, however, to allow for the possibility that the gates for each pitch are longer than the period of the !BPM. This way I can have overlapping pitches, which give a nice shimmer to the cloud of pitches.

I've tried to write a script that can instantiate several overlapping events with a sort of "programmable voice allocation." (I've tried a different way to get at this problem by using the polyphony of a sequencer Sound, but experienced what seem to be latency-related problems).

So, with my not-nearly-yet-ripe CapyTalk intuitions, I've come up with the following godawful script, which really freaks my Kyma ("Unhandled exception: My subclass should have overridden one of my messages."

| x |
x := (!BPM / 60) inverse removeUnits.
0 to: 3 do: [ :i |
Tink
start: ( i * x ) s
gate: (1 bpm: !BPM dutyCycle: !Duty)
freq: (!KeyPitch12 hz * ((!rando * 12) of: #(1 1 {9/8} {9/8} {5/4} {4/3} {4/3} {3/2} {3/2} {5/3} {5/3} {15/8}))) ]

So, I'm ready now to roll down the window and ask for directions. Many thanks for any help you can give me.

Otherwise, if you'd prefer to keep !BPM variable, you could put a MIDIVoice on the Input to the Script and set its polyphony to 4 (the number of overlapping Sounds you have now).

Another approach is to use an AnalogSequencer with a length of 1 and your random expression in the Pitches field and Polyphony set to 4.
