I would expect them to show similar latencies to the app in such cases when heavy disk I/O occured > what if the note is read from a MIDI interface connected to a standard serial > port ? ( are there some disadvantages over the soundcard's own MIDI port ?) You would want to set the low latency flags on the serial port. The serial code by default does processing 100 times a second in batches Alan
