.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.
.SH OPTIONS
.TP
