The issue is measurable/reproducible: I attached a vkeybd to kmidimon both directly and though an usb midi interface physically 'loopbacked'.
The time between the 'direct' and the 'routed' event is under '5' on the -generic kernel, and between 100 and 150 on the -rt one. -- USB MIDI jitter https://bugs.launchpad.net/bugs/300806 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
