I guess there's some misunterstanding, I don't think that miditest.pd or
generally PD-MIDI is faulty, you're completely right: as long as nothing
is connected, nothing can get printed.
My problem lies in having my MIDI-controller connected on PD-startup.
Right now my only possibility to connect without GUI is to execute
"aconnect 20, 128" after PD has opened MIDI. To speak more concretely:
after starting PD with mididev-parameters I want to have Arduino
connected to PureData in aconnect -l. This works on my desktop machine
but not on the fresh updated raspberry.

 I retried, but I already tested various configurations. For now I tried:
-mididev and -midiindev with parameters 0/1/2/3/20/21
-midiaddindev 'Arduino Leonardo' and 'Arduino Leonardo MIDI 1' which
unfortunately didn't open any ALSA Client.

As expected compiling 0.46.7 didn't help. Root privileges didn't help

I'm pretty clueless what my next steps would be to trace this issue. As
MIDI works in ALSA and PD I think there has to be a communication
problem on opening the ALSA client. Maybe I'm missing a package? What's
involved in setting the MIDI connection on startup? I supposed that PD
uses aconnect itself to connect to MIDI devices, but maybe there's
something different going on?
