That looks keen, but I'm having a hard time figuring out how to get pd
to talk to my MIDI devices.
$ pd -alsa -listdev
reading startup file: /home/fugalh/.pdrc
input devices:
1. Sound Fusion CS46xx (hardware)
2. Sound Fusion CS46xx (plug-in)
3. Keystation (hardware)
4. Keystation (plug-in)
output devices:
1. Sound Fusion CS46xx (hardware)
2. Sound Fusion CS46xx (plug-in)
3. Keystation (hardware)
4. Keystation (plug-in)
API number 1
no midi input devices found
no midi output devices found
couldn't open MIDI input device 0
couldn't open MIDI output device 0
opened 0 MIDI input device(s) and 0 MIDI output device(s).
So it's seeing my keyboard as an audio device but not a midi device. Any ideas?
