Alsa Midi /dev/snd/seq missing

[njeremic]

Hey forum
i just got my a20 micro and having quite some issues
i want to use it for music/audio/dsp/synth prototyping with puredata
so far i got alsa to play audio trough headphones, but no sound from puredata
also midi does not work "out of the box"
all the software i would like to use says /dev/snd/seq is missing
does anybody knows how to configure it?
does anybody uses a20 for music/audio?
best
