Summary0007074: Looping MIDI adds silence at the beginning of the loop
DescriptionI have a 8 Bars Drum Loop 2 channels (1 channel kick and snare, 2 channel HH), Notes are sent trough midi out to a Roland MC-505, if I play a Loop from 0:0 to 9:0 there is a silence at the beginning. I checked the option "Do seamsless looping" at preferences but same thing. Also when I press loop I can hear first note sounds out of tempo.
Steps To ReproduceCreate a 8 bars sequence and loop. Send it through midi out. Recorded with audacity from Audio Input.

Can you please try and reproduce with a nightly build. There was a fix recently that may be related to the behaviour you are seeing.

What version of 5.4 was this specifically? Was it an official build? 32 or 64 bit?

Hi sorry about the late response. I download and tried Ardour_64bit-5.4.399-dbg-gcc5. but is the same thing. if I press Play it start on time, but if I press Loop I can hear some notes are delayed and there's this silence at the end of the loop. Thank you very much for your help

I tried this file on the new version 5.5 and got the same problem. I noticed that if I enable "Play Loop as Transport Mode" and turn off and on the loop button while playing I get a strange behavior with the MIDI notes going out. It seems loop mode and play mode are separated entities.
