.SH NAME

lsmi-keyhack \- Linux Pseudo MIDI Input -- Keyboard Hack
|
|
.SH SYNOPSIS
|
|
.B lsmi-keyhack
|
|
.RI [ options ] " files" ...
|
|
.SH DESCRIPTION
|
|
|
|
This driver is for a hacked AT / PS/2 keyboard functioning as a MIDI
|
|
controller.
|
|
|
|
It is somewhat specific to the author's own hardware, but, since it relies a learning
|
|
capability rather than a fixed keymap, it should be equally useful for
|
|
others wishing to build their own fake MIDI keyboard. Of course, such a
|
|
keyboard will not be velocity sensitive, but this project is a good way to
|
|
salvage both an old QWERTY keyboard and a manual from a decrepit analog
|
|
organ or cheap PCM noise-maker.
|
|
|
|
The driver supports up to 88 musical keys, three footswitches, and several
|
|
additional buttons for control and data entry. It has the rather unfortunate
|
|
side-effect of rendering the console useless, unless, of course you have
|
|
another (USB) keyboard to type on.
|
|
|
|
.SH USAGE
|
|
|
|
Distribution specific init scripts are not included. The drivers may be
|
|
started from init, your .bashrc, by qjackctl, etc. In order to be run by a
|
|
non-root user the drivers must have access to the device files in /dev/input.
|
|
This may be accomplished by adding a group 'input', adding desired users to
|
|
this group, and configuring udev to assign the appropriate ownership to files
|
|
in /dev/input. It should be perfectly safe to run the drivers as root,
|
|
however.
|
|
|
|
For realtime scheduling (the \-R option), either use set_rlimits, or set the
|
|
appropriate POSIX capabilities on the executable:
|
|
.P
|
|
/sbin/setcap cap_ipc_lock,cap_sys_nice=ep /usr/bin/lsmi-joystick
|
|
.P
|
|
The lsmi.SlackBuild script already includes RT scheduling support.
