Re: [Musix-users] Re: Musix 0.50

      I play guitar and sing in a couple of bands.  In a few
weeks, I will be going out of town to play and sing. 
Unfortunately, I am on my own, neither band can
travel.  So, I will go by myself with some backing
tracks.

Did I mention that I play guitar?  Even though there
is great software available for playing audio files
(ecasound is my favorite), I can't use my hands.  I
have a very powerful MIDI foot pedal, the FCB101 from
Behringer, but there is no software that I have found
to control the loading and playback of audio files via
MIDI.

After years of searching, I came across dispmidi from
Div Slomin:
http://www.sreal.com:8000/~div/midi-utilities.  I am
not a developer, but I was able to hack the code to
output MIDI information into a useful format.  So,
there it was, a utility to parse the incoming MIDI
stream from my foot pedal and launch a file, any file.
 Here are a couple of commads I used:

dispmidi /dev/midi | grep Program | cut -f 4 | xargs
-i script.sh {}

dispmidi /dev/midi | grep Program | cut -f 4 | xargs
-i  ecasound {}.wav

The first command takes the program number and pipes
it into a script via xargs and the script launches the
file.

The second command actually launches a file named with
the number of the MIDI program number.  When that MIDI
program number is detected, the corresponding file is
launched.

So, there it is.  MIDI controlled (well, more like
started than controlled) playback of audio files.

As I said before, I am not a developer, but I have
some  enhancements I would like to make:

1) Read a configuration file to set MIDI channel and
directory where the playback files reside

2) Make it alsa/jackd aware so as to be able to send
out MIDI signals. For example, be able to send a MIDI
sequence in real-time, synchronixed to audio file
playback

3)  Keep it a command-line utility.  It doesn't take a
lot of computing power to stream a .wav file through a
sound card so it would be useful task for older
hardware.  Also, I plan to run this headless and it
would be easier to do this from a command line rather
than having to set up some GUI frambuffer application.

What do you think?
