Understood ! So we can use these functions at our own risk... no problem. It's true that I didn't find clear doc on the web regarding the sequence management (including rewind or markers setting), using Meta events or SysEx. Regarding the time scrolling, I used a simple mechanism: imported MIDI file (as a sequence) is truncated to a specified beats range (define with a GUI), and then played by your PlaySequence function. So it's a beats scrolling, not depending on tempo changes (which is more convenient compared to a time scrolling). I'm also facing a difficulty: the beats markers are linked to signature. But on a few MIDI files, the 1st note is NOT positionned at BEAT 1, which introduces a bias in the beats display in PLAY mode. Just to illustrate that developing a robust MIDI PLAYER is not a walk in the park...! So still a bit of work...

Really impressed by your work, MattyD ! Everything works perfectly... provided we make the effort to deep dive (a bit) into MIDI commands ! And the help files are key to make the best from your MIDI library My question: why do you qualify your "events sequences" functions as Experimental ? Can you provide us with known limitations ? I developed a MIDI PLAYER which seems to work, based on these functions. Thank you again for this nice job !
