DESCRIPTION
xmp is a tracked music module player. It plays many module formats
including Fasttracker II (XM), Noise/Fast/Protracker (MOD), Scream
Tracker 3 (S3M) and Impulse Tracker (IT). Use xmp --help for a complete
list of supported formats.
xmp can play through several output devices including the Open Sound
System sequencer, linear and ulaw PCM audio devices or mixing to a raw
or WAV file.
OPTIONS
-8, --8bit
Convert 16 bit samples to 8 bit. You may want to use this mode
to save memory in the sound device (AWE cards will ignore this
mode and always work with 16 bit samples).
-a, --amplify factor
Amplification factor for the software mixer. Valid amplification
factors are 0 (normal), 1 (x2), 2 (x4) and 3 (x8). Warning:
amplification factors higher than 0 may cause distorted or noisy
output.
-b, --bits bits
Set the software mixer resolution (8 or 16 bits). If ommited,
The audio device will be opened at the highest resolution
available.
-c, --stdout
Mix the module to stdout.
--chorus depth
Set chorus depth (if available).
-D device-specific parameter
Pass a configuration parameter to the device driver. See the
DEVICE DRIVER PARAMETERS section below for a list of known
parameters.
-d, --driver driver
Select the output driver. If not specified, xmp will try to
probe each available driver.
--fix-sample-loop
Force sample loop start in samples instead of 16-bit words. This
option affects only MOD files.
-F, --click-filter
Use the LPF filter to remove clicks from the software mixer
output.
-f, --frequency rate
Set the software mixer sampling rate in hertz.
-h, --help
Show a short summary of command-line options.
-i, --interpolate
Enable software mixer linear interpolation.
--load-only
Exit after loading the module&.
-l, --loop
Enable module looping and backward pattern jumps.
-M, --mute channel-list
Mute the specified channels. channel-list is a comma-separated
list of decimal channel ranges. Example: 0,2-4,8-16.
-m, --mono
Force mono output (default is stereo in stereo-capable devices).
--nocmd
Disable interactive commands.
--nofilter
Disable IT filters. When using the software mixer, IT filters
can significantly increase CPU usage on slow machines. In this
case, disable filtering with this option.
-n, --nearest
Enable software mixer nearest neighbor interpolation.
--nopan
Disable dynamic panning. This option can be used to prevent
clicking when playing in AWE32 cards. Module formats that rely
only in dynamic pan setting to produce stereo output (e.g. XM)
will use the MOD channel panning (LRRL).
--norc Don’t read the configuration files.
-o, --output-file filename
Set the output file name when mixing to raw or WAV files. If ´-´
is given as the file name, the output will be sent to stdout.
-P, --pan num
Set the percentual panning amplitude.
--probe-only
Exit after probing the audio device.
-R, --random
Play modules in random order.
--realtime
Play modules in realtime priority (available for FreeBSD).
-r, --reverse
Reverse the left/right stereo channels.
--reverb depth
Set reverb depth (if available).
--show-time
Display elapsed and remaining time.
-S, --solo channel-list
Play only the specified channels. channel-list is a comma-
separated list of decimal channel ranges. Example: 0,2-4,8-16.
-s, --start pos
Start playing the module from the position pos.
--stereo
Force stereo output.
-T, --tempo bpm
Set the initial tempo in beats per minute (default is 125).
-t, --time time
Specifies the maximum playing time to time seconds.
-u, --unsigned
Tell the software mixer to use unsigned samples when mixing to a
file (default is signed).
-V, --version
Print version information.
-v, --verbose
Verbose mode (incremental). If specified more than once, the
verbosity level will be increased (no messages will be displayed
when the player runs in background).
DEVICE DRIVER PARAMETERS
Use the option -D to send parameters directly to the device drivers.
Multiple -D options can be specified in the command line.
OSS sequencer:
-D awechorus=mode
Set the chorus mode in AWE cards. Valid modes range from 0 to 7
(CHORUS_1, CHORUS_2, CHORUS_3, CHORUS_4, FEEDBACK, FLANGER,
SHORTDELAY, SHORTDELAY2).
-D awereverb=mode
Set the reverb mode in AWE cards. Valid modes range from 0 to 7
(ROOM1, ROOM2, ROOM3, HALL1, HALL2, PLATE, DELAY, PANNINGDELAY).
-D opl2
Open the sequencer in OPL2 FM mode instead of sample mode. This
parameter is required to play modules with FM instruments (RAD,
AMD, S3M).
-D dev=device_name
Set the sequencer device to open. Default is /dev/sequencer.
OSS software mixing:
-D frag=num,size
Set the maximum number of fragments to num and the size of each
fragment to size bytes (must be a power of two). The number and
size of fragments set a tradeoff between the buffering latency
and sensibility to system load. To get better synchronization,
reduce the values. To avoid gaps in the sound playback, increase
the values.
-D dev=device_name
Set the audio device to open. Default is /dev/dsp.
-D nosync
Don´t sync the OSS audio device between modules.
HP-UX and Solaris audio:
-D gain=value
Set the audio gain. Valid value goes from 0 to 255. The default
is 128.
-D port={s|h|l}
Set the audio port. Valid arguments are s for the internal
speaker, h for headphones and l for line out. The default is the
internal speaker.
-D buffer=size
Set the size in bytes of the audio buffer. The default value is
32 Kb.
File output:
-D big-endian
Generate big-endian 16-bit samples (default is the machine byte
ordering).
-D little-endian
Generate little-endian 16-bit samples (default is the machine
byte ordering).
INTERACTIVE COMMANDS
The following single key commands can be used when playing modules:
q Stop the currently playing module and quit the player.
f Jump to the next pattern.
b Jump to the previous pattern.
n Jump to the next module.
p Jump to the previous module.
SPACE Pause the module.
1, 2, 3, 4, 5, 6, 7, 8, 9, 0
Mute/unmute channels 1 to 10.
! Unmute all channels.
Interactive mode can be disabled using the --nocmd command line option.
NOTES
When using the OSS sequencer with an AWE card, xmp will wipe out any
soundfonts already loaded in the card.
EXAMPLES
Play module muting channels 0 to 3 and 6:
xmp --mute=0-3,6 module.mod.gz
Play modules in /dev/dsp using the default device settings (unsigned
8bit, 8 kHz mono):
xmp -o/dev/dsp -f8000 -m -b8 -u module.lha
Play all XM modules in the /mod directory and all subdirectories in
random order, ignoring any configuration set in the xmp.conf file:
xmp --norc -R ‘find /mod -name "*.xm*" -print‘
