Here is another MIDI software synthesizer backend for DosBox' MPU-401
emulation. I found it in a forum and because it didn't make up its way to the
DosBox project at SourceForge, I post it now, so that it won't get lost.
It is aimed at emulating a Roland MT-32 through the use of the "mt32emu"
library, which is available at http://sourceforge.net/projects/munt/
Apply first to current DosBox CVS my previous patch named "MIDI
wavetable software synthesis backend" or apply by hand.
I mainly added a new "configure" item to automatically detect the
availability of the "mt32emu" library.
To use it, add entries to dosbox.conf like:
When you first run DOSBox with mt32 enabled you will have to wait a
minute or two because it has to create the waveformcache-<samplerate>-
440.00.raw based on the rate you choose. Also the MT32 Emulation is very
CPU intensive and right now the samplerate default is 22050 which is
decent enough (though it sounds better at 44100).
You should be able to use DOSBox with MT32 emulation as long as you
have a proper MT32_CONTROL.ROM and a MT32_PCM.ROM in your
current directory (case sensitive).
