Avoid doing conversions in the nodes between Midi formats, just assume the imput is what we expect and output what we naturally produce. For ALSA this means we produce and consume Midi1 or Midi2 depending on the configurtation. All of the other modules (ffado, RTP, netjack and VBAN) really only produce and consume MIDI1. Set the default MIDI format to MIDI1 in ALSA. Whith this change, almost everything now produces and consumes MIDI1 again (previously the buffer format was forced to MIDI2). The problem is that MIDI2 to and from MIDI1 conversion has problems in some cases in PipeWire and ALSA and breaks compatibility with some hardware. The idea is to let elements produce their prefered format and that the control mixer also negotiates and converts to the node prefered format. There is then a mix of MIDI2 and MIDI1 on ports but with the control port adapting, this should not be a problem. There is one remaining problem to make this work, the port format is taken from the node port and not the mixer port, which would then expose the prefered format on the port and force negotiation to it with the peer instead of in the mixer.
