@Maarten thanks a lot for your kind words!
Yes, the session will be switched instantly. As the session load time is not guaranteed (normally it will be very quick and you would not really notice it), i’d recommend to put as much of a live performance as possible into a single session, you have 36 clips available, normally this should be good for even a longer performance in conjunction with the song mode patterns.
If you’re preparing a performance that needs multiple sessions and that requires very exact transitions between the parts, you could potentially use an external MIDI tool for a synced session switch via MIDI program changes.
