I don't fully understand the implications of your proposal. Would it replace the current /dev/umidi* devices and audio/jack_umidi? Or is it just another option? Does it have an impact on usability or latency (or latency correction)? Frankly I'm not too familiar with the whole interaction between JACK, ALSA MIDI and alsa-seq-server. I suppose the alternative would be a better integration of jack_umidi with device detection? Or do we have to go through the alsa-seq-server anyway for applications like QTractor? > > https://www.freshports.org/audio/a2jmidid > > Can be used together with latest version of: > > https://www.freshports.org/audio/alsa-seq-server I never used midi hardware for anything serious, but I'll give it a test drive this weekend.
