QMidiCtl and QMidiNet (was Re: [PlanetCCRMA] Pd + PulseAudio?)

[Niels Mayer]

Rui's note on qjackctl prompted me to look at http://www.rncbc.org and then
http://www.rncbc.org/drupal/node/191 which lead to
http://qmidictl.sourceforge.net/ and http://qmidinet.sourceforge.net/ ...

Both of these apps look awesome. Any chance these can be made available
through PlanetCCRMA or even better, through fedora which already carries
up-to-date versions of qtractor.

Also, one issue I've found w/ controllers in general is that there is a need
for a simple scripting language, or a comprehensive set of "built-in special
functions" to handle "state" and "computation" in midi
controllers. Do
qmidictl or qmidinet have any solutions for this?

One quick example I ran into recently. I've setup a very useful remote
control to a TC Electronics Finalizer. One of the features it has is a
MIDI-controlled "fader" (e.g. for doing smooth fadeouts/fadeins). I've got
that mapped to a 100MM slider on a behringer controller and it's SWEET. But
also, it's linear. What I need is to map the midi controllers 0-127 to a
logarithmic curve so as to match human loudness perception. This doesn't
seem possible in qmidiroute... (?) What tools would allow this, or any other
"computed" mapping to be done? (see also see
http://old.nabble.com/using-qmidiroute-for-midi-device-control....-ts2796...
 )

Is there an easy way to add scripting languages to Qt apps? (something like
'Guile' would be nice).

PS: thanks to http://www.rncbc.org/drupal/node/183 , I will also be taking a
look at qtractor-0.4.5-1.fc12.x86_64 which i've installed, but not yet
explored ( rosegarden4-10.02.1-1.fc12.x86_64 works well for me so far).

Any of these can be installed easily on F12  (assuming all prereq libs, e.g.
qt4, already installed, or install qtractor-0.4.5-1.fc12.x86_64 which will
ensure all prereq libs are installed).  This worked for me using Fedora 12,
stock kernel 2.6.32.9-70.fc12.x86_64.

Summary: No need to compile your own, the SUSE 11.{1,2} RPMs run nicely
(just like
azr3-jack<ftp://ftp.pbone.net/mirror/packman.iu-bremen.de/suse/11.1/x8...
).
Still exploring, as I just got these two apps fired up...

How to do it: Grab the appropriate RPM's from here:
qmidictl-0.0.1-1.rncbc.suse112.i586.rpm<http://downloads.sourceforge.n...
qmidictl-0.0.1-1.rncbc.suse112.x86_64.rpm<http://downloads.sourceforge...
qmidinet-0.0.1-1.rncbc.suse112.i586.rpm<http://downloads.sourceforge.n...
qmidinet-0.0.1-1.rncbc.suse112.x86_64.rpm<http://downloads.sourceforge...

And install in fedora like this:

Note the binaries are located in /usr/local/bin/ and the menu entry for
qmidictl ends up in "Other" by default -- use 'Preferences>Main Menu'
to
move them to 'Sound & Video' .

Any chance you are already a fedora packager, or would like to become 
one [1] to create and look after packages like these, that you are 
interested in ?

As you have seen, packagers of software make it easy for other people to 
use particular software. While it can be a little bit daunting to start 
with, there are many people who can offer tips and advice should you 
like to become a Fedora packager. You might also like to contribute in 
other testing/qa roles, eg test of updated packages like k3guitune [2] 
(guitar tuner).
