wildmidi.cfg - Config file for libWildMidi

libWildMidi

Contains the patch configuration for libWildMidi and location of Gravis Ultrasound compatible patch files.

Instead of a patch configuration, the file given to libWildMidi may also be a SoundFont2 (.sf2) file, or a timidity.cfg style file that names one via the soundfont directive. The file type is detected by content, not by extension.

dir ~/guspats/
source /etc/wildmidi.cfg
bank 0
0 acpiano.pat amp=110 env_time4=300
1 brpiano.pat amp=100
drumset 0
25 snarerol keep=env amp=225 note=60
26 snap	note=65

Some patch file editors switch the 4th and 5th envelopes around making the sound play much longer than intended in players that stuck to the Gravis Ultrasound patch standard. A fix that detects this oversight is applied automatically since WildMidi 0.4.3; this option is accepted for backwards compatibility and has no effect.
Forces WildMIDI to amplify samples to their maximum level ignoring the amp=% in the patch lines of the config.
Forces WildMIDI to amplify samples to their maximum level then apply the amp=% in the patch lines of the config.
Change the search path for config and patch files to dir-name. This is specific to the current config file and carried to any included config file unless they have their own dir setting. Any included file that has its own dir setting does not effect the dir setting of the current config file.
Include the settings from include-config. Any patch already set will be over-ridden by the included config file.
Render using the SoundFont2 file sf2-file instead of Gravis Ultrasound patches. Relative paths are resolved against the config file directory, the same as source. This allows an existing timidity.cfg that names a SoundFont to be used as-is.
The patches following this setting belong to MIDI instrument bank N.
The patches following this setting belong to MIDI drum bank N.

Example: 0 acpiano.pat amp=110

This is the MIDI patch number the instrument belongs to.
The filename of the Gravis Ultrasound compatible patch file. If the filename is missing the .pat extension, libWildMidi will add .pat when attempting to load the file.
Force the volume of the samples in this patch to volume% prior to using it.
Use note midinote when playing the samples in this patch. NOTE: this is for instruments listed under drumset.
Play the samples in this patch with the loop, when normally we would not for this instrument.
Use the envelope data in this patch, when normally we wouldn't for this instrument.
Do note hold the note after the 3rd envelope until note off, which is what happens if the sustain bit is set in the patch file.
Do not jump to 6th envelope on note off, which is what happens if the clamped bit is set in the patch file.
Set the envelope level to level with 1.0 being maximum, and 0.0 being minimum.
Example: set 5th envelope level to 10% - env_level[0-5]=0.1
Set the envelope time to time with a resolution of 1/1000th of a second. This setting is the time it should take for the envelope to reach maximum level.
Example: set 1st envelope time to 1sec - env_time0=1000
Example: set 3rd envelope time to 0.5secs - env_time2=500
Set the room width for the reverb engine in meters. fval is a float value in meters. Minimum setting is 1.0 meter, maximum setting is 100.0 meters, and default is 15.0 meters.
Example: set room width to 30 meters - reverb_room_width 30
Set the room length for the reverb engine in meters. fval is a float value in meters. Minimum setting is 1.0 meter, maximum setting is 100.0 meters, and default is 20.0 meters.
Example: set room length to 40 meters - reverb_room_length 40
Set the listener position across the room width for the reverb engine. fval is a float value in meters between 0.0 and reverb_room_width; values outside the room reset to the room centre. Default is half the room width.
Set the listener position along the room length for the reverb engine. fval is a float value in meters between 0.0 and reverb_room_length; values outside the room reset to 3/4 of the room length. Default is 3/4 of the room length.
