aseqjoy - Joystick to ALSA MIDI Sequencer Converter
Aseqjoy maps each axis of a joystick device to a specific MIDI
controller. Moving the joystick along an axis will cause aseqjoy to emit
MIDI controller messages via ALSA's sequencer API. The value of the controller
message represents the joystick's position along the axis (eg 'left' -> 0,
'middle' -> 63, 'right' -> 127). Note that you can run aseqjoy with the
'-r' commandline switch to use fine MIDI control change messages instead
(with 14 bit resolution).
Aseqjoy uses the ALSA sequencer API to emit the MIDI events. Therefor it
creates and output port named after joystick used. You can then use for example
aconnect, QjackCtrl or the alsa-patch-bay to connect an aseqjoy
instance to an input port of your choice.
Note: Some joysticks may have to be calibrated (with jscal) before
they can be used efficently.
Display help info
- -d [joystick]
Select the joystick to use for aseqjoy, where [joystick] is an integer value
from from 0 to 3 effectivley selecting devices js0 to js3.
Verbose mode - aseqjoy will output information about the MIDI events
- -0 [controller]
Select the MIDI controller ID for axis 0. As a default value aseqjoy will use
10 + the axis ID, so for axis 0 that would be 10 + 0 = 10.
- -1 [controller], -2 [controller], -3 [controller],
Just like -0 this will set the controller IDs for axes 1, 2, 3.
Use fine MIDI control change messsages instead (14 bit insstead of 7 bit
After aseqjoy has started successfully all motion detected by the selected
joystick device will cause MIDI controller messages to be emitted via the
corresponding ALSA sequencer output port. The controller IDs are either the
default values (10, 11, 12 ...) or the ones given as commandline options.
Pressing a joystick button will cause aseqjoy to switch the MIDI channel. On
startup channel '1' is selected. Pressing joystick button 2 will cause channel
2 to be selected. Other buttons work accordingly.
