Error handling

[notator]

I think the host ought to enclose the call to synth.send(...) in a try..catch clause, since there's no way to guarantee that the synth isn't going to throw an exception. Maybe there's a programming error in there somewhere.

But I don't think software synths should throw exceptions deliberately. Its probably very time-consuming.

My versions of the synthesizer code now use console.warn(...) when the synth recieves a message that it can't deal with. If the synth warns the host while the host is being programmed, then the host can avoid sending unnecessary messages. This has worked fine for me.

Can the calls to console.warn be left in production code, or must there be two versions of the synth: one that warns, and one that just ignores unimplemented messages?

Is there a better way to do this?
