Your tracks (in Plays Free, right?) are not in sync maybe because you haven’t chosen the trig quantizing(you can go for 16 to get a 1-bar quantize, like the Ableton default).

If the tracks have this option chosen, chances of the out-of-sync are due to the absence of the clock going (read: the sequencer) so they start as soon as they get triggered without aligning to the quantization value.

So I suggest you to have the sequencer running to perform the Plays Free mode…that can sound weird, but I spent a nasty day, months ago, just to have the Plays Free tracks working in an expected way…

Also can u make a crappy video to show this mess after Parts change?
