Sounds like something may be interrupting the MIDI data stream.

Shared IRQ with the MIDI to computer device, something like that.

Background program may be doing it also.

For the record, I enjoy excellent MIDI tracking and recording from both MIDI keyboard controllers and MIDi guitars here. Give or take the 120ppq resolution of BiaB, I don't experience such lags or interruptions. So it is indeed a possible goal to attain.
