Subject: [linux-audio-user] Soft synths with ALSA

I've finally got a recent (cvs) version of Alsa to compile and run
with my shiny new Delta 66 and moldy old CS-4237 card. Mostly things
are working pretty well, but I can't seem to get MIDI input to any
oss-compatible app that expects it.

Midi output seems to be OK... playmidi -f works, I can hear the cruddy
old FM synth.

So, has anyone got any of the following working with midi control
under ALSA 0.9x?

 SpiralSynth
 SpiralSynthModular
 XSynth
 RTSynth

I would think any of them should work fine, using oss emulation for
raw midi input, but it's not happening... I just don't seem to be
getting any events from the keyboard.

I guess the first step would be: What's the simplest way to test if
you've got anything coming in from the midi controller?

Oh yeah, I did check in /proc/asound/oss-devices, it looks fine to me:

$ cat /proc/asound/oss-devices
  0: [0- 0]: mixer
  3: [0- 3]: digital audio
 18: [1- 2]: raw midi
 26: [1-10]: hardware dependent
 16: [1- 0]: mixer
 19: [1- 3]: digital audio
