7 What it does: Each axis of the joystick device is mapped to a specific MIDI
8 controller. Moving the joystick along an axis will cause aseqjoy to emit
9 MIDI controller messages via ALSA's sequencer API. The value of the controller
10 message represents the joystick's position along the axis (eg 'left' -> 0,
11 'middle' -> 63, 'right' -> 127).
13 aseqjoy uses the ALSA sequencer API to emit the MIDI events. Therefor it
14 creates and output port named after joystick used. You can then use for example
15 aconnect (from alsa-utils) or Robert Ham's alsa-patch-bay to connect an aseqjoy
16 instance to an input port of your choice.
21 - Linux System with correctly configured Joystick support.
22 - A working ALSA 0.9 installation.

35 In some cases the joystick may not utilize the full range of available
36 controller values - in this case you should use "jscal" from the joystick
37 pacakge (most distributions feature this package) to calibrate your joystick
38 before running aseqjoy. Note: Analog PC joysticks are no high-precision
39 devices - so even after calibrating the device you might not always be able
40 to reach "0" or "127" controller values - depending on the joystick you
43 Start aseqjoy - if you have a working Joystick (Nr. 0 - use the -d switch to
44 select other joysticks) aseqjoy will detect that and each axis to a controller
52 From now on aseqjoy emits events over the "Joystick0" output port. To make use
53 of these events in another application use for example the alsa-patch-bay
54 to connect that output port to another application's input sequencer port
55 (for example the "terminatorX" input port for terminatorX). After you bound
56 the controllers to certain controls you should see how moving the joystick
57 affects the corresponding control.
