Version 2.5 of jack-keyboard can be downloaded
from:
http://pin.if.uz.zgora.pl/~trasz/jack-keyboard/jack-keyboard-2.5.tar.gz
The biggest change is switching from hand-written makefiles to autotools.
This should make packagers' life easier.
jack-keyboard is a virtual MIDI keyboard - a program that allows you to
send JACK MIDI events (play ;-) using your PC keyboard. It's somewhat
similar to vkeybd, except it uses JACK MIDI instead of ALSA, and the
keyboard mapping is much better - it uses the same layout as trackers
(like Impulse Tracker) did, so you have two and half octaves under your
fingers.

Hi, would you accept a patch that makes it work with ALSA midi
alternatively? (Just checking before doing anything ;)

Starting a jack daemon just to be able to send some midi to some midi device
is maybe a burden sometimes.. I like the idea of jack midi for internal
routing between applications, especially between Sequencers and Softsynths.
It lightens the burden on softsynth and sequencer implementers which would
otherwise have to take into account all kinds of scheduling and priorityu
issues. But MIDI also has more purposes than that..
Jack MIDI is not the answer to all things MIDI IMHO..

Rewriting it from scratch seemed easier. And probably was easier.

Sure it does. But what makes ALSA MIDI more suitable for that purpose?

Personally, I like to think of ALSA MIDI as a legacy interface.

Zero added latency for one. jackd only makes sense for inter-process delivery
of MIDI signals. For inter-machine sending of midi where the other machine
might be a hardware synth, it doesn't make sense at all to send the signal
through another daemon..
This is shortsighted IMHO..

Ok, you convinced me. I'll finish splitting jack-keyboard.c into
jack-dependent and jack-independent parts and then let you know about
how it looks like.

AFAIK this is just wrong, JACK ALSA MIDI backends are normal ALSA MIDI
clients, there is nowhere you get additional latency.
