Before you start you need to have ALSA installed and configured correctly. This man page cannot cover
all general ALSA topics, but here are a few things to check when things do not seem to be working.
CheckingALSA
1. First check that the correct sequencer modules are loaded for your sound card:
- For a card with an external Midi connection, you need to load snd-seq-midi.
- For the OPL2/3 internal synthesiser you need to load snd-synth-opl3.
- For the AWE32/64 internal synthesiser you need to load snd-synth-emu8000.
- For the SB Live! internal synthesiser you need to load snd-synth-emu10k1.
- (Let me know of any more)
2a If you have an AWE32/64 or SB Live! you will need to load the sounds with sfxload in the same way as
for the standard kernel drivers.
2b If you have the OPL3 FM synthesiser you will have to load the FM instruments with sbiload. See note
below.
3. Make sure that the synth in the mixer is turned up and unmuted if appropriate.

Because you may have more than one sound card and each sound card may have several MIDI connections, you
have to tell pmidi which one to use.
First find out what the possibilities are for your system:
If you run:
pmidi -l
it will give you a list of the possible devices that it can play to. On my system I get:
PortClientnamePortname
64:0 Rawmidi 0 - EMU10K1 MPU-401 (U EMU10K1 MPU - 401 (UART)
65:0 Emu10k1 WaveTable Emu10k1 Port 0
65:1 Emu10k1 WaveTable Emu10k1 Port 1
65:2 Emu10k1 WaveTable Emu10k1 Port 2
65:3 Emu10k1 WaveTable Emu10k1 Port 3
128:0 FLUID Synth (28152) Synth input port (28152)
129:0 Client-129 TiMidity port 0
129:1 Client-129 TiMidity port 1
Any of the port numbers in the first column can be used with pmidi. In the example above the first one is
the external Midi port, the next four are the internal wave table synthesiser. Then there are two
software synthesisers running, FluidSynth (http://www.fluidsynth.org) and Timididy.
If you don't see anything listed then check that the correct ALSA modules are loaded as in the section
"Checking ALSA".
