I'm gonna go with "more than sufficient" but...it's a (multicore) i7-6700 @ 3.4 Ghz with 32GB of RAM. I have an SSD but I'm running BiaB off the traditional hard-drive which is a pretty usual 7200RPM.

>>Does the slow down also happen in RB or any other DAW or music device?

I don't really grasp DAWs but I managed to get sound out of a couple other MIDI-thru apps and they, too, lag.

>>Are there tempo changes in the song?

I'm not even at the "song" level. I'm just talking pressing keys on the keyboard and noticing a delay which seems to change (and mostly increase).

>>If there are no tempo changes and the song starts out OK but then slows down it sounds like you are pushing something to the limit. Maybe the CPU, sound card, RAM, HD, etc but without the computer spec information it is hard to many any conclusion.<<

It does sound like that, but the computer shows no signs of stress whatsoever. Like, the CPU sitting with BiaB open and idle looks exactly the same as the CPU sitting with BiaB open and me hitting the keys. I opened the Performance Monitor and added a few likely candidates that might be stressed and, no, there's not the slightest indication that BiaB even registers when I'm hitting keys, or when I'm generating and playing something random (except that when it's playing a full, randomly-generated piece, it reads more from the disk).
