TiMidity command line option
-A [n][,m](a)
Multiplies the master volume by n % Default value is 70%Higher amplification makes louder sounds You can specify the drumpower, ratio of drum volume from the other channels The allowedvalues of amplification range from 0 (no sound) to 800
Optionally to put `a' character along with -a option, or to use--volume-compensation , instructs TiMidity++ toregularize the volume You can easily gain dynamic range
For example:
volume 90%, drum power 100%, compensation is off
volume 70%, drum power 120%, compensation is off
volume 90%, drum power 120%, compensation is off
volume 70%, drum power 100%, compensation is on
volume 90%, drum power 100%, compensation is on
volume 70%, drum power 120%, compensation is on
volume 90%, drum power 120%, compensation is on
-a, --[no-]anti-alias
Turns on antialiasing Samples are run through a lowpass filterbefore playing, which reduces aliasing noise at low resamplingfrequencies
-B n,m , --buffer-fragments=n,m
For the Linux/FreeBSD/OSS/ALSA/Windows sound driver, selects thenumber of buffer fragments in interactive mode Increasing the numberof fragments may reduce choppiness when many processes are runningIt will make TiMidity++ seem to respond sluggishly to fastforward, rewind, and volume controls, and it will throw the statusdisplay off sync Specify a fragments number of 0 to use the maximumnumber of fragments available
-C n , --control-ratio=n
Sets the ratio of sampling and control frequencies This determineshow often envelopes are recalculated -- small ratios yield betterquality but use more CPU time
-c file , --config-file=file
Reads an extra configuration file
-D n , --drum-channel=n
Marks channel as a drum channel If channel is negative, channel-n is marked as an instrumental channel If n is0 , all channels are marked as instrumental

Make TiMidity++ evil For the Win32 version, this increases thetask priority by one It can give better playback when you switchtasks at the expense of slowing all other tasks down
-F, --[no-]fast-panning
Turns on fast panning to accommodate MIDI pieces that expect panningadjustments to affect notes that are already playing Some files thatdon't expect this have a habit of flipping balance rapidly betweenleft and right, which can cause severe popping when the -F flagis used
In the current version of TiMidity++ this option is a toggle
-f, --[no-]fast-decay
Toggles fast envelopes This option makes TiMidity++ faster butthe release time of the notes are shortened
-g sec , --spectrogram=sec

q, --quiet=n
Decreases verbosity level This option is cumulative
t, --[no-]trace
Toggles trace mode In trace mode, TiMidity++ attempts todisplay its current state in real time For the Linux sound driver,this is accomplished through the use of short DMA buffer fragments,which can be tuned via the -B option

Adds path to the library path Patch, configuration, and MIDIfiles are searched along this path Directories added last will besearched first Note that the current directory is always searchedfirst before the library path
-M name , --pcm-file=name
TiMidity++ can play a PCM file instead of a MIDI file If``auto'' is specified, TiMidity++ tries to open foomidwav orfoomidaiff when playing foomid If ``none'' is specified, thisfeature is disabled Otherwise just plays name
-m msec , --decay-time=msec
Modify envelope volume decay time msec is the minimum numberof milliseconds to sustain a sustained note
-m 0
Disable sustain ramping, causes constant volume sustains (default)
-m 1
Effectively behaves as if all sustains are ignored, volume ramping isthe same as normal stage 3
-m 3000
A note at full volume will decay for 3 seconds once it begins tobe sustained (assuming the regular stage 3 rate would not cause it todecay even longer) Softer notes will of course die sooner
-N n , --interpolation=n
Sets interpolation parameter This option depends on the-EFresamp option's value
cspline, lagrange
Toggles 4-point linear interpolation (default is on)
n point interpolation using Newton polynomials n must bean odd number from 1 to 57

Place output on file , which may be a file, device, or HP-UXaudio server, depending on the output mode selected with the -O option The special filename `-' causes output to be placed onstdout
-P file , --patch-file=file
Use patch file for all programs
-p [n](a)
Sets polyphony (maximum number of simultaneous voices) to n
Optionally to put `a' character along with -p option, or to use--polyphony-reduction , instructs TiMidity++ to enableautomatic polyphony reduction algorithm
-Q n[,...](t)
Cause channel n to be quiet n can carry out packagespecification by `,' If n is 0 , all channels are turnedoff Continuously, specifying -n , channel n is turnedback on
On the other hand, to put `t' character after -Q option or touse --temper-mute describes temperament mute This muteschannels of specific temperament type n For presettemperament, n can range 0 to 3 For user-definedtemperament, n can range 4 to 7

Unload all instruments from memory between MIDI files This canreduce memory requirements when playing many files in succession
-V power , --volume-curve=power
Set the power of volume curve The total amplification becomesvolume^power 0 (default) uses the regular tables Anynon-zero value causes all midi to use the new user definedvelocity/volume/expression curve (linear: 1 , ideal:~1661 , GS: ~2 )

-Z file , --freq-table=file
Cause the table of frequencies to be read from file This isuseful to define a tuning different from 12-equal temperament If``pure'' is specified, TiMidity++ plays in trial pure intonation
-Zpure [n(m)] , --pure-intonation=[n(m)]
Play in trial pure intonation by Key Signature meta-event in the MIDIfile You can specify the initial keysig by hand, in case the MIDIfile does not contains the meta-event Optionally, n is thenumber of key signature In case of sharp, n is positive Incase of flat, n is negative Valid values of n are in theinterval from -7 to 7 In case of minor mode, you shouldput `m' character along with -Zpure option
