My first suspect would be AC Ground Loop between computer and the tape. But since you don't tell us if that tape is ADAT or Analog tape, if audio connects are digital or analog, nor what brand or model, and also if that buzz is present, even at slightly less volume, *before* starting Transports, that's just a starting place.

Posting a snippet of the noise in mp3 or even a short .wav format so that I can hear and analyze the offending noise can narrow things down quite a bit, too.

It would also be a worthwhile troubleshooting test if you were to try recording in the same hookup without the MIDI syncing, just to find out if that noise is still present. That could narrow things down quite a bit.
