I'm the keys half of a keys / drums / vocals duo. We use a lot of midi backing tracks for modern up-tempo stuff, because that gives us the sound people expect. All midi tracks are carefully edited (by me) to leave space for "live" keys and drums, we are not in the karaoke business!

There is not a click track as such but there's usually something to latch onto.

Initially keeping to such strict tempo is very hard and hugely frustrating, but it can be done with discipline and practise. Note that taking a tune from rehearsal to proper live action will accentuate any slight deviations as the adrenaline takes over, so be doubly careful!

I remember the first time I tried to play to a sequenced backing track, I was astonished to discover that my ability to keep to a strict tempo was total pants, given that I was telling the drummer off for excessive drifting!

You may find it necessary to adjust the tempo tracks to allow more give and take within a tune.

Good luck!
