i think you will find the ultimate answer to latency is you need to monitor directly during recoding while listening to the recorded instruments. later, if you want to substitute the TD kit (i always record both the MIDI and the audio) with TT or some other drum VI, then do that after recording when the latecy in the mix will be consistent and the same. vs the live vs rountrip echo / VI latency all DAW introduce regardless of the ASIO vs any other driver techniqute.
