yeah, it's buggy alright. like, really buggy! here's what I found:
gates on both the cv and midi stay wide open (no note off) unless you set swing to something (51 will do). with swing set to 50, the midi synth I had on seq 2 wouldn't even mute (again, no note off).
BUT, with swing on 51 midi gates seem to be trigger only, ie exceedingly fast. a synth with no release just sounds like clicks. Setting TIEs works to elongate the notes, but then you can't play consecutive 16ths.
finally, if you leave a midi channel on swing 50, not only will you get no note offs but its one 16th out of sync with any swung tracks.
analogue clocking is a bit of a mess at the moment is my conclusion
edit: actually on further looking: the issue with midi being triggers also occurs on the cv. unless a note is tied it's a v. short trigger (with swing applied)
