TiMidity -- Experimental MIDI to WAVE converter

List of changes

0.2h to 0.2i

• Renamed most source files to fit into 8.3 characters and less. Sorry.
• Changes by Davide Moretti <dmoretti@iper.net>: Incorporated the changes to allow TiMidity to compile and run under Win32 platforms (tested with Windows 95 and Windows NT for Intel). Read README.W32 for more information.
• Tcl/Tk interface by Takashi Iwai <iwai@dragon.mm.t.u-tokyo.ac.jp>. Read README.tk.
• DEC port by Chi Ming HUNG <cmhung@insti.physics.sunysb.edu>. Read README.DEC.
• A few bugfixes: WAVE headers, shell substitution, Linux audio O_RDWR, dumb/ncurses segfault (thanks to everyone who sent a fix for this ;)
• Reversed the sense of the -F option to get rid of some nasty pops.
• Attempted to merge Makefile.{SUN|SOLARIS|HPUX|DEC} back into Makefile to conserve the world's ketoprofen reserves.
• Lowered default amplification to 70% to get a bit more dynamic headroom.

0.2g to 0.2h

• Warning! This is a Vincent Pagel release... more official release when Tuukka comes back from hollydays, err, his exams actually.
• I've added a Motif interface with files selection, time scale cursor and other blue widgets. More gadgets to come. Changes are in motif_* files, but also a big structure change in timidity.c and playmidi.c as it is now the interface that choose the name of the next file to play.
• Added so called "nice" icons
• Pipe communication between Motif interface and the program.
• Antialiasing filtering now works even with looping patch, nice when playing on a SUN at Ulaw at 8Khz ( option -a )
• Added a Makefile.HPUX since make on HP does not understand the += notation
• Thanks to Gilles Dauphin, works on Solaris

0.2f to 0.2g

• Wrote a little WAVE to patch converter and added ".wav" to DECOMPRESSOR_LIST to allow using wave files as simple instruments. This was Davor Jadrijevic's suggestion from some time back. New file: wav2pat.c
• Took out ADJUST_PANNING_IMMEDIATELY and put in a command line option "-F" for "turn off _F_ast panning". Running out of letters for command line options.
• Error check in read_config_file to make some noise when directories are specified as config files.
• Squashed a segfault that resulted from resampling past loop end (FINALINTERP, when incr > 1<<FRACTION_BITS).
• Sweep computation overflow with seashore.pat fixed.
• The portion of sample data from loop_end to data_length is now played if the instrument doesn't have a loop or an envelope. Some patches (e.g. Fretnoyz from the ProPats 3.0 set) contain garbage between loop_end and data_length, so there's a new config file option "strip=tail" to drop it off.
• Reverse loops are now done "right".
• Slight LOOKUP_HACK cleanup. There's a "final_volume_t" type that's either an uint8 or an int32, whichever is required for mixing computations, and a FINAL_VOLUME() macro to convert an int32 to the required type.
• Changed the "THING := $(THING) junk" assignments in Makefile to "THING += junk"'s. Hopefully the latter is understood by more makes than the former. The whole mess will be replaced by a configure script within a few releases.
• Split up mix_data in mix.c to make it easier to look at.

0.2e to 0.2f

• Moved mixing functions out of resample.c. New files: mix.c, mix.h.
• Added midia.cfg config file for the Midia patch set.
• Added Shawn McHorse's loop optimizations and LOOKUP_SINE config.h option.
• Added Shawn's FAST_DECAY command line switch -- config.h option FAST_DECAY now sets the default for this switch.
• USE_LDEXP config.h option, in case your compiler converts ldexp() into a straight fscale, and fscale is faster than fmul on your machine.
• Fixed WAVE header bug -- the lengths were 44 bytes short. Thanks to Alexey Marinichev for noticing.
• Added PATCH_EXT_LIST option to config.h, so you don't have to change every filename in your configuration file when you decide to compress your patches.
• Added external utility "bag". New file: bag.c, read it for info.
• Added "extern" to the s32towhatever() prototypes in output.h.

0.2d to 0.2e

• Riccardo Facchetti's S-Lang-based user interface: a more efficient alternative to ncurses. Options in Makefile.
• Rearranged options in Makefile to make various combinations easier to select.
• LOOKUP_HACK config file option: horrible experimental kludge to substitute table lookups for multiplication. First attempt to use uLaw as sample format failed miserably. Now using 8-bit linear, which is fine for Sound Blaster owners. It only saves ~20% of CPU on a Pentium, but let me know what it does to your setup.
• Changed instrument loading to add the Sustain flag to all patches which have the Looped flag set.
• Implemented All Notes Off, All Sounds Off, and Reset All Controllers events. The Day of the Tentacle intro music uses the first and plays OK now. The other two might work, or they might throw your machine into a damaging infinite binary loop.
• Implemented Bank Select controller. Sort of emulates the SCC-1 (I think): use Control Change 00 xx, where xx is the tone bank you want. Totally untested. Some MIDI files use Control Change 0 for something else, generating loads of warnings.
• In config.h, changed the default command line for shorten to work with version 1.22. The old one was for some ancient version which I finally got around to replacing.
• Fencepost error in resampling fixed by Vincent Pagel.
• Fixed problem with bidirectional loops and vibrato.

0.2c to 0.2d

• Volume computations rewritten to use both floating point and integer multiplication.
• Tremolo and vibrato handling. Some tuning parameters are available in config.h.
• Fixed-pitch, non-looped instruments are now resampled at load time. Note that fixed-pitch instruments can't be pitch-bent.
• Cheaper click removal scheme. Removed I_WANT_THE_CLICKS_BACK option from config.h, added MAX_DIE_TIME definition. Moved resampling and mixing functions from playmidi.{c,h} to new files: resample.c, resample.h.
• Percussion instrument pitches can now be specified independently of the note they're assigned to. Melodic instrument pitches can also be forced. Extra options in config file -- see the manual. Thanks to Davor Jadrijevic for his suggestions.
• Loops and envelopes are now removed from all percussion instruments by default. This should eliminate cymbal crashes being cut short.
• Changes in gravis.cfg to override some instrument parameters that would be guessed incorrectly.
• Vincent Pagel's experimental antialiasing filter. This doesn't interact very well with looping yet, so it's only applied to non-looped instruments. Use the command line option "-a" to enable the filter. New files: filtering.c, filtering.h.
• Enabled fast forward & rewind in non-trace mode in ncurses_ctl.c.
• Fixed a problem with envelopes -- envelope handling still isn't perfect, but skipping the "Attack 2" phase was dumb.
• Added ADJUST_PANNING_IMMEDIATELY to config.h, default on (no change from previous behavior).
• Silly bug in adjusting non-enveloped voice volumes fixed.
• Small change in ncurses_ctl to display 100 for maximum volume and expression.
• After listening to a GUS, made FAST_DECAY default to on.
• Riccardo Facchetti's patch to config.h: Not all Linux systems are little-endian.
• Riccardo's alternative keyboard commands in ncurses_ctl.c. First step towards porting to MS Windows -- you can press F1 to get help!
• DANGEROUS_RENICE config.h option. Thanks again to Riccardo.

0.2b to 0.2c

• Fixed pitch bend sensitivity again. NRPN controls are now correctly ignored.

0.2a to 0.2b

• Francesco Zanichelli's patches to get the Sun version to actually compile.
• Victor Langeveld's patches to get the FreeBSD version to actually compile.
• Fixed pitch bend sensitivity. Thanks again to Vincent Pagel for the information.
• Expression now defaults to 127, as with the SCC-1. Some things may sound a bit loud.

0.1a to 0.2a

• Internal changes for easier porting to other systems. long long's are gone, floating point is used instead. Command line options changed.
• Output to HP-UX audio server by Vincent Pagel.
• Output to Sun audio device based on Francesco Zanichelli's port of version 0.1a.
• Output to ZyXEL modems based on Rob Janssen's uLaw patches.
• FreeBSD options in Makefile and linux_audio.c. Check for DSP fragment capability. (Thanks to Victor Langeveld.)
• ncurses interface changes. Trace mode optional.
• Fixed bug -- the last MIDI event was getting eaten, causing stuck notes at the end of songs. (Reported by Anthony Cruz.)
• Pitch-bend sensitivity added, with a hack to process "Data entry (MSB)" events. Thanks to Vincent Pagel for info on this...
• Run-time configuration of quiet and percussion channels.
• Volume computation fix. You can now crank the volume up to 800%.
• Slower envelopes. Pianos sound better, harps sound worse. Applause in Beethoven's 5th should sound better... Thanks to Tim Norman for comments on this. CPU usage went up -- see option FAST_DECAY in config.h.
• Panning and volume controls no longer affect notes that have already been turned off.
• Click reduction on by default. CPU usage went up -- see option I_WANT_THE_CLICKS_BACK in config.h.
• Sample volume adjustment into compile time option -- see option ADJUST_SAMPLE_VOLUMES in config.h
• SMPTE time in divisions field in MThd. Untested.
• Quote some special characters in filenames before popen().
• Hack to accept old patch files and files that claim to contain 0 instruments and/or layers.
• Behavior when reading Gravis .cfg files changed -- syntax error reported instead of segmentation fault.

0.1a

• First release. Plays MIDI files under Linux.
