yes, everything should be synced with ableton.
top right in the floating window is your global quantization. by default, recording doesn’t start on a specific beat, it’s just quantized to whatever u have set here. with a pre-roll, it’ll delay the record go by the given pre-roll value, then it quantizes the start of recording.
if you enable the punch-in checkbox however, you can have it always record on a specific beat, but u have to manually set it. there’s a way to do this from the monome (explained in the controls section of the readme), but the button is to the right of ‘punch-in’ if u want to use midi or the mouse.
