- TiMidity -- Experimental MIDI to WAVE converter
- Copyright (C) 1995 Tuukka Toivonen <toivonen@clinet.fi>
-
- --------------------------------------------------------------------------
-
- Frequently Asked Questions with answers:
-
- --------------------------------------------------------------------------
- Q: What is it?
-
- A: Where? Well Chris, TiMidity is a software-only synthesizer, MIDI
- renderer, MIDI to WAVE converter, realtime MIDI player for UNIX machines,
- even (I've heard) a Netscape helper application. It takes a MIDI file
- and writes a WAVE or raw PCM data or plays it on your digital audio
- device. It sounds much more realistic than FM synthesis, but you need a
- ~100Mhz processor to listen to 32kHz stereo music in the background while
- you work. 11kHz mono can be played on a low-end 486, and, to some, it
- still sounds better than FM.
-
- --------------------------------------------------------------------------
- Q: I don't have a GUS, can I use TiMidity?
-
- A: Yes. That's the point. You don't need a Gravis Ultrasound to use
- TiMidity, you just need GUS-compatible patches, which are freely
- available on the Internet. See below for pointers.
-
- --------------------------------------------------------------------------
- Q: I have a GUS, can I use TiMidity?
-
- A: The DOS port doesn't have GUS support, and TiMidity won't be taking
- advantage of the board's internal synthesizer under other operating
- systems either. So it kind of defeats the purpose. But you can use it.
-
- --------------------------------------------------------------------------
- Q: It doesn't work. It doesn't play anything, and it prints out error
- messages and stuff.
-
- A: Read the INSTALL file, or get someone to read it for you. Then go
- through the rest of the documentation, there really isn't that much.
- Once you've got it working in the distribution directory, here's a list
- of further things to do:
-
- Get a full General Midi set. Create a directory, say C:\TIMIDITY or
- /usr/local/lib/timidity, and put all the *.pat files in it. Also toss
- in all of the *.cfg files that came with the TiMidity distribution.
- Then edit timidity.cfg:
-
- Uncomment and edit the dir statement to read "dir c:\timidity" or
- whatever, and uncomment the "source gravis.cfg" statement.
-
- Now run the program: "timidity -L c:\timidity <midi files>"
-
- That should do it really. Note that TiMidity always checks the current
- directory first, so things might get confusing if you've got different
- copies of the config files in various places. "timidity -idvv
- <midifile>" will list all attempts to open patch files, which might
- help.
-
- If it still doesn't work, email me and/or the author of the particular
- port, if using a non-Unix version.
-
- --------------------------------------------------------------------------
- Q: I tried playing a MIDI file I got off the Net but all I got was a
- dozen warnings saying "No instrument mapped to tone bank 0, program
- xx - this instrument will not be heard". What's wrong?
-
- A: The General MIDI standard specifies 128 melodic instruments and
- some sixty percussion sounds. If you wish to play arbitrary General
- MIDI files, you'll need to get more patch files.
-
- There's a program called Midia for SGI's, which also plays MIDI
- files and has a lot more bells and whistles than TiMidity. It uses
- GUS-compatible patches, too -- so you can get the 8 MB set at
- ftp://archive.cs.umbc.edu/pub/midia for pretty good GM compatibility.
-
- There are also many excellent patches on the Ultrasound FTP sites.
- I can recommend Dustin McCartney's collections gsdrum*.zip and
- wow*.zip in the "[.../]sound/patches/files" directory. The huge
- ProPats series (pp3-*.zip) contains good patches as well. General
- MIDI files can also be found on these sites.

- Q: This MIDI file used to work fine with version 0.0001z but now it
- suddenly sounds weird. What happened?
-
- A: Something changed in the way TiMidity interprets MIDI or patch
- parameters. If you think it changed for the worse, try to find out
- which patch/MIDI file is causing problems, exactly what is different,
- and if possible, why :) Also, try another MIDI player or device to
- hear how the file is played correctly. Then mail me.
-
- If you just upgraded from 0.2c or lower, note that you'll need to
- update your configuration files. See "gravis.cfg" for an example.
-
- --------------------------------------------------------------------------
- Q: Some files have awful clicks and pops.
-
- A: Find out which patch is responsible for the clicking (try "timidity
- -P<patch> <midi/test-decay|midi/test-panning>". Add "strip=tail" in
- the config file after its name. If this doesn't fix it, mail me the
- patch.
-
- --------------------------------------------------------------------------
- Q: I'm playing Fantasie Impromptu in the background. When I run Netscape,
- the sound gets choppy and it takes ten minutes to load. What can I do?
-
- A: Here are some things to try:
-
- - Use a lower sampling rate.
-
- - Use mono output. This can improve performance by 10-30%.
- (Using 8-bit instead of 16-bit output makes no difference.)
-
- - Use a smaller number of simultaneous voices.
-
- - Make sure you compiled with FAST_DECAY and PRECALC_LOOPS enabled
- in config.h
-
- - If you don't have hardware to compute sines, recompile with
- LOOKUP_SINE enabled in config.h
-
- - Recompile with LOOKUP_HACK enabled in config.h.
-
- - Recompile with LINEAR_INTERPOLATION disabled in config.h.
-
- - Recompile with DANGEROUS_RENICE enabled in config.h, and make
- TiMidity setuid root. This will help only if you frequently play
- music while other processes are running.
-
- - Recompile with an Intel-optimized gcc for a 5-15%
- performance increase.
-
- - Use "bag".
-
- --------------------------------------------------------------------------
- Q: I made TiMidity setuid root. Starting Netscape now takes *twenty*
- minutes!
-
- A: Wow.
-
- --------------------------------------------------------------------------
- Q: I can't reach the WWW page. Is the URL okay?
-
- A: The URL is fine, but clinet.fi is connected to the Internet via two
- monkeys banging 5-bit PPP on a pair of teletypewriters. If you have
- trouble connecting, please try again later in case they've gotten
- banana in the mechanism or started eating the tape or something. The
- source is also available at
- ftp://sunsite.unc.edu/Linux/apps/sound/players/ although not every
- release gets there. You can also try a mirror at
- http://www.loria.fr/~pagel/
-
- Other foreign mirror sites would be welcome -- if you can spare a few
- megs of http space on your server, please email me!
-
- --------------------------------------------------------------------------
- Q: Is there any kind of TiMidity Contest where I could win great
- prizes like a trip to â•“stersundom, Finland to have dinner with the
- author and have my picture taken with a polar bear and a free
- year's subscription to TiMidity Inside Edition beta versions and...
-
- A: Sure. Announcing the TIMIDITY PATCH TREASURE HUNT-AND-DESTROY!
