Build and install
-----------------
See the INSTALL file for full details. Normally you just need to use the
following commands:
./configure
make
make install
To compile from a Mercurial checkout, first use the following commands
first to create the configure script:
aclocal
autoconf -a
automake
or if you have autoreconf:
autoreconf -i
Before use
----------
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)
2.a 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.
2.b 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.
Usage
-----
pmidi [-p client:port ...] [-l] [-d delay] file ...
-p client:port - A alsa client and port number to send midi to
-l - List possible output ports that could be used
-d delay - Delay after song ends (default 2 sec)
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:
Port Client name Port name
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, and the next
four are the internal wave table synthesiser on the SoundBlaster Live!
If you don't see anything listed then check that the correct ALSA modules
are loaded as in the section "Before use".
Running pmidi
-------------
You specify the port or ports to use with the -p option,
or by setting the environment variable ALSA_OUTPUT_PORTS.
For example to use port 0 on client 65:
pmidi -p 65:0 song.mid
or
export ALSA_OUTPUT_PORTS=65:0
pmidi song.mid
A list of client ports can be supplied, which will be used
if the midi file contains port select sequences.
pmidi -p 65:0,65:1,65:2,65:3 song.mid
You can also use spaces to separate with suitable quoting
on the command line.
OPL3 FM synthesiser
-------------------
(This note was provided by Dmitrii Sadovskii)
This is what has to be done to use the OPL3 FM synthesiser with pmidi
(provided that the ALSA's respective card module is already loaded)
# modprobe -k snd-synth-opl3
> sbiload -l (same as pmidi -l)
Port Client name Port name
64:0 External MIDI 0 MIDI 0-0
65:0 OPL3 FM synth OPL3 Port
> sbiload -p65:0 --opl3 std.o3 drums.o3
> pmidi -p65:0 sample.midi
sbiload:
alsa-tools/seq/sbiload/
Written by Uros Bizjak <uros@kss-loka.si>

sbiload works with ALSA driver 0.9.0beta2 and later.
Use it with native ALSA sequencers, such as pmidi-1.5.1
or later.
Laptops:
the sound card (or the driver?) does not keep the instrument
patches after suspend, so sbiload should be called at resume
(as well as alsactl restore)
It should be said that ALSA+pmidi plays with better quality than OSS/Free
but that in general FM synthesisers are not great for good midi.
