I am running the latest ‘ready to run’ Ardour 6 on Raspberry Pi 4 with an iConnectMIDI interface. So far so good - I can record MIDI. However while recording, notes are ‘stuck’, they become long bars that do not end. When I stop recording, the stuck notes go away. While it does not seem to affect playback, I use the real-time MIDI view for monitoring during recording. In this case, the MIDI recordings are anywhere from minutes to hours. The ability to monitor the recording is impacted by the ‘stuck’ lines on the piano roll. I do not experience this in other Windows or iOS DAWS that record MIDI, with the same source and interface.
Has anyone else experienced this, and is there a setting that might address it? Thanks!
