Summary0006541: parallel playback of linked midi regions->no note-offs
DescriptionMake a midi region with some midi notes, dublicate it and let them play parallel on two different tracks witch different instruments. The result is that the instruments don't react to note-off messages anymore. if one unlinks those midi regions, the problem vanishes.
Additional InformationI'm using the official build of Ardour 4.2 on an archlinux 64bit system.
TagsNo tags attached.

confirmed, I can reliably reproduce this.

probably related to (same midi source iterators are used in different contexts)

Ardour 4.2-64-g1387e75 has a fix for this issue, please test.

It's not an ideal fix however (it may not perform well for huge midi regions). further work is needed.

I'm afraid I can't test the fix of, because I'm not a subsriber and have no access to the nightly builds (because I haven't got a credit card and paypal does not allow for subscribtions without. But I do support Ardour, of course:))

I can confirm this is still fixed. Tested with nightly build 5.4.357 (64bit linux).

Marking as resolved.

It seems that this bug reappeared.


I can reproduce it with Ardour 5.12 (official binary) as well as with the current Git version (built from source: b69d818).
