This sequence, is needed to make my USB-to-MIDI cable work while connected from the beginning:
1. Power on the Linux box
2. Wait until all processes are running and connected
3. Power on the keyboard
I'm connecting ALSA MIDI and JACK via aj-snapshot after all processes are up.
If I use ALSA MIDI, via a2jmidid or a2jmidi_bridge, the above is needed. If I use JACK MIDI, the keyboard has to be on first. Any thoughts as to whether this is to be expected?
