[PD] No midi as root

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
