Hey - I wrote a guide on concepts for dynamic tempo control in Ableton Live. Obviously as Ableton Live 11 has the new TEMPO FOLLOW function there is some focus on that BUT it covers TAP and dynamic BPM control with Ableton Live 10 + Max for Live as well. Its free/pay what you like(!) - you can get it here: https://blog.abletondrummer.com/ableton-live-tempo-tempo-follower-guide
Just in case anyone s looking on how to set up the TEMPO FOLLOW feature I made a little video tut for that: How to make Ableton Live FOLLOW your drums in real-time - Tutorial for TEMPO FOLLOW Ableton Live 11 - YouTube
