Minimizing the bufferSize

[duysqubix]

I've been working on a super simple midi-based synthesizer based heavily on your approach to handling the audio signal. I'd like to keep working on it but I can't seem to get the buffersize down enough so that the latency isn't so noticeable. I can get it down to about 22 milliseconds but any lower and there's a clicking sound. Do you have an idea as to why the smaller buffer sizes become problematic?

My start is here, if you're curious:
