At any rate, synced recording works well. It accepts sync and sends it as well, but it only seems to be able to start an actual synched recording, you can’t arm it and then wait for an external cue.
It doesn’t make much of a difference, I recorded six separate takes from the Deluge now and then mixed them together, all takes recorded with midi sync, no latency. I don’t know how it handle 30 minute ambient meanders, but a few tight disco beats, it managed just fine
