So if your sampling rate is 48000 Hz then the processing engine will launch into processing 64 samples 750 times per second .... or once every 1.333333 seconds. 1.33333 milliseconds - big difference there! Also, when using message timestamps (aka latency), the OffsetOut ugen compensates for the difference between the scheduled time and the control block boundary. So you can actually get *sounding* timing resolution that is better than control rate. hjh : H.
