Hello all,
I am running pd on Debian with a 2.4.20 + preempt + lowlatency kernel and the alsa drivers. I didn't add the capabilities patch because I hadn't heard about it. I struggled compiling the kernel and am hesitant to go through it again, as what I have is good enough for now.
My problem: When I run pd as root (to use -rt) I have no midi. Everything works well when I run as a user. As root, everything works except for midi. I assume that I have missed something simple. Any help will be appreciated.
pmidi -l gives Port Client name Port name 64:0 External MIDI 0 MIDI 0-0 65:0 OPL3 FM synth OPL3 Port
and pmidi -p 64:0 foo.mid plays the keyboard.
TIA Allan

This won't help you much, because 64:0 is an ALSA sequencer port, but Pd only uses the raw midi devices: /dev/midi0, /dev/midi1, ..., /dev/midi20
Make sure the module snd-seq-oss is loaded and you have setup ALSA to support OSS-emulation. You might want to refer to the Linux MIDI-Howto, the chapter about Softsynths and aconnect (which I wrote and which apparently has helped many people so far).
