Is it possible to make a frame-independent click using TimeSynth?

A little update - I’ve realised that the timing stuttering is not caused by a conflict between Timesynth and the game thread but Audio Buffer Underruns. I’ve set my device audio buffer to 1024 which I would imagine is plenty but still get these warnings:

So the question is, how do you initialise the Pool Size for TImesynth (ideally in C++)? Or is there another buffer I should be setting?
