Timidity works just swell as a midi softsynth in combination with alsa.
Taken from the timidity docs:
| This document describes about the Advanced Linux Sound Architecture
| (ALSA) sequencer interface. The ALSA sequencer interface communicates
| between ALSA sequencer core and timidity. The interface receives
| events from sequencer and plays it in (quasi-)real-time.
| On this mode, TiMidity works purely as the software real-time MIDI
| render, that is as a software MIDI synth engine on ALSA.
| There is no scheduling routine in this interface, since all scheduling
| is done by ALSA sequencer core.
|
| For invoking ALSA sequencer interface, run timidity as follows:
| % timidity -iA -B2,8 -Os -q0/0 -k0
| The fragment size is adjustable. The smaller number gives better
| real-time response. Then timidity shows new port numbers which were
| newly created (128:0 and 128:1 below).
| ---------------------------------------
| % timidity -iA -B2,8 -Os -q0/0 -k0
| TiMidity starting in ALSA server mode
| Opening sequencer port 128:0 128:1
| ---------------------------------------
| These ports can be connected with any other sequencer ports.
| For example, playing a MIDI file via pmidi (what's an overkill :-),
| % pmidi -p128:0 foo.mid
| If a midi file needs two ports, you may connect like this:
| % pmidi -p128:0,128:1 bar.mid
| Connecting from external MIDI keyboard may become like this:
| % aconnect 64:0 128:0
CPU load is neglectable so I definitely recommend timidity.
Nice to see I'm not as much of a moron as I thought, I had pretty much
the same problems of not knowing that you need to specifically run a
softsynth even if sound is otherwise all setup when there's no hardware
synth on the card.
