Title: Playing VST Synth, Latency Appears And Disappears
While playing a VST instrument, sometimes there is latency (delay between pressing a note and hearing the note), and sometimes there is no latency. The latency comes and goes.
Cause Of Problem:
The most likely cause of this, is that there are other things running on your computer while you are playing (such as downloading updates, running maintenance, or installing updates), and the overhead of those other processes are bogging-down the processor, causing the latency.
Make sure other processes are not running on your machine while you play the KeyMusician Keyboard (unless you have a fast machine).
