.SH DESCRIPTION
|
|
.B amidi
|
|
is a command-line utility which allows to receive and send
|
|
SysEx (system exclusive) data from/to external MIDI devices.
|
|
It can also send any other MIDI commands.
|
|
|
|
.B amidi
|
|
handles only files containing raw MIDI commands, without timing
|
|
information.
|
|
.B amidi
|
|
does not support Standard MIDI (.mid) files, but
|
|
.B aplaymidi(1)
|
|
and
|
|
.B arecordmidi(1)
|
|
do.
|
|
|
|
.SH INVOKING

.I -p, --port=name
|
|
Sets the name of the ALSA RawMIDI port to use.
|
|
If this is not specified,
|
|
.B amidi
|
|
uses the default port defined in the configuration file
|
|
(the default for this is port 0 on card 0, which may not exist).
|
|
|
|
.TP
|
|
.I -s, --send=filename
|
|
Sends the contents of the specified file to the MIDI port.
|
|
The file must contain raw MIDI commands (e.g. a .syx file);
|
|
for Standard MIDI (.mid) files, use
|
|
.B aplaymidi(1).
|
|
|
|
.TP
|
|
.I -r, --receive=filename
|
|
Writes data received from the MIDI port into the specified file.
|
|
The file will contain raw MIDI commands (such as in a .syx file);
|
|
to record a Standard MIDI (.mid) file, use
|
|
.B arecordmidi(1).
|
|
|
|
.B amidi
|
|
will filter out any Active Sensing bytes (FEh), unless the
|
|
.I -a
|
|
option has been given.
|
|
|
|
.TP
|
|
.I -S, --send-hex="..."

Sends the bytes specified as hexadecimal numbers to the MIDI port.
|
|
|
|
.TP
|
|
.I -d, --dump

|
Prints data received from the MIDI port as hexadecimal bytes.
|
|
Active Sensing bytes (FEh) will not be shown, unless the
|
|
.I -a
|
|
option has been given.
|
|
|
|
This option is useful for debugging.
|
|
|
|
.TP
|
|
.I -t, --timeout=seconds
|
|
Stops receiving data when no data has been received for the specified
|
|
amount of time.

|
|
|
If this option has not been given, you must press Ctrl+C (or kill

|
.B amidi\fR)
|
|
to stop receiving data.
|
|
|
|
.TP
