Are you releasing a note's buses at the moment when the user requests the
note release, or at the moment when the envelopes are all finished and the
synths have ended?

Oh wait... now I see that you have "reltime.wait" in the release code. Does
"reltime" really match the release times of all the synths?

ddwVoicer needs to handle a related problem: not about buses, but it has to
know which slots are active, which are free, and which ones can be stolen if
needed. I considered a release-time parameter for the user to set, but
decided that it would be too easy for the voicer's "release time that I
think is happening in the server" to disagree with the release time in the
synth. So I ended up using NodeWatcher to track, and I don't mark a resource
as free until the synth is really gone.

synTest = synTestArray.detectIndex { |item| item == 0 };
if(synTest.notNil) { synTestArray.put(synTest,num) } { /* else fail, maybe
throw an error? */ };

"1.do {  }" is redundant.

If you have only one case, there's no benefit over "if" (but there's no
penalty for using "case"  either).
