The attached test session (using setBfree as an LV2 instrument) is an example of incorrect behaviour. Both end loop and end session markers are slightly beyond the end of the MIDI clip, so A3 should send note-off, go to the end and return to the beginning. It only happens the first time the loop is played. Sending note-off doesn't really work the second time A3 reaches the end of the clip.

Sorry about localized marker names, but pressing L is universal anyway :)

I noticed this bug awhile back too but it has since been fixed, for me at least. I opened up your session and had no problem with midi while looping it. What build are you using. Latest revision is 13974.

Can no longer reproduce with Ardour 4.7 - closing

There have been quite a few changes to midi-looping since.
