Timidity PPC/68k notes
---------------------------------------
If you have a 68060 I suggest you to use the 68k
and not the PPC version, because the PPC lacks some of
the features of the 68k one, but on the other hand the
68k one is slow, too slow also on my 040@33. On a 060
it runs very well though. Also, the 68k version has a
nice MUI GUI, and sounds very well via AHI. Too bad
that the author lost all the sources.
The PPC version needs the ixemul.library in the PPC
version, so don't forget to add a big stack (I use at
least 300000) or you will get crashes. The PPC version
works perfectly under ppc.library emulation under the
WarpOS system, but has also a nasty bug, it can't be
stopped, with break or control-c, so you always have
to wait for the end of the file. Also it seems not to
like too much AHI, I often get distorted sound, it
doesn't happen while outputting to file. Anyway, to
hear something with AHI you have to add the "8"
switch to the -O parameter, or you will not hear
anything.
I think that the best way to use
TimidityPPC is to use it as MIDI2WAV converter, as it
is really fast, and can convert to ram in few seconds.
When I want to listen to a MIDI, I convert it in wav to
ram: with the ppc version and then play it with
SongPlayer or Play16. If you have a 060 you can play in
realtime without the conversion step.
The two tools you find are provided to give a fast way
to do the conversion without messing too much with the
shell. They are simple AmigaDOS scripts, assuming that
you have the RequestFile and RequestChoice files in C:
as with the standard installation.

Timidity or GMPlay ?
---------------------
Actually there are 2 MIDI players for Amiga that don't
need additional hardware. For a lot of time I used
GMPlay, and think that it's a great software too, so
here is a little comparison between the 2:
GMPlay is faster than Timidity, If you have a 030 or
a 040 you should use it. Timidity68k is way too slow
for real time playing unless you have a 060.
The samples used in the distribution of GMPlay are not
of a great quality, except for the drums. Timidity
comes with no patches, but now you have downloaded
this archive, so it doesn't matter :-)
There are some new tone banks on Aminet, but the
quality is still too low, and the sound never gets
realistic.Timidity covers almost every MIDI instrument
and the banks (except for some drums, that are
downloadable separately anyway, maybe I'll do another
release), and with this set of patches the quality is
great. GMPlay seems to be no more developed. Both can
be used to play MIDI files on Internet, but the PPC
version distorts the sound, I really hope to see a new
version... Timidity is open sourced: if you are a good
programmer, you could port the newer versions.
