Hi,
I'm looking for some kind of midi patchbay (in software, using alsa), that
can also process midi events, like, for example, converting note on to
control change events, etc.
In particular, I'd like to be able to:
- route midi events between input and output ports, and activate different
setups by sending midi messages
- split midi channels, e.g. to send the upper part of a keyboard to one
output port, and the lower part to another
- change midi velocity curves
- convert sustain pedal (cc 64) to appropriate note off events (I know
this one is very specific)
Is there any tool (or set of tools) that can do this?
Thanks,
Dominic

Try Qmidiroute; you can get it at http://alsamodular.sourceforge.net/

I have been interested in Qmidiroute, too, but never managed to figure out
how
to build it from sources. It doesn't even have a proper Makefile, just a bunch
of .h and .cpp files. How does one build programs like that?

depending on your distro, it may be neccessary to adjust paths in
make_qmidiroute. As it was developed on SuSE, it contains SuSE paths.

Yes, Pd can do all this, but you have to have Pd on your machine. I love
Pd, but unless it can generate a stand-alone application (that doesn't
require Pd) then it isn't really meeting the need.
It's a shame Matthias stopped writing his MIDI utilities. I've tried to
reach "holborn" (aka the author of midirgui) but had no success.
A software clone of the MEP4 clone would be a very sweet MIDI utility.
Perhaps a bounty would convince a developer to spend an afternoon
writing such a tool ?

I kindly disagree here: Why should a standalone app be better than
having an application written in a glue language like Pd is here?
Using Pd the way I proposed is similar to using a Python or Perl
script. Yes, you need to have Perl or Python installed, but these are
pretty standard on every distribution. IMO Pd is pretty standard as
well on a Linux musician's computer. And for this midi route stuff no
Pd externals are needed. Not everyone can programm in Python or Perl,
and especially GUI programming can be tricky with both, however GUI
programming in Pd really is trivial.
The real advantage of using Pd or whatever "scripting language" is
that one is not bound to the ideas the programmer had, who wrote the
midi translator: It's easy to add or remove features.
IMO there is no need for a developer to spend an afternoon writing
something like Qmidiroute, when in Pd custom translators can be built
in a couple of seconds. And one doesn't even have to be a Pd meister
for doing it. Proof:

This "patch" translates every note played to a program-change.

using Qt4 and RtMidi, it should be easy to create such an app. You
"only" need someone who has the time to do it :) .

?!?!?
qmidiroute requires qt and the c library. I haven't seen a stand-alone app
since the 8-bit era.

Hey Dave,
Although RTMix has not been updated for a while, you can do this in 3 lines
of script and do so not only for MIDI->MIDI, but also for any combinations
of MIDI, OSC, generic network protocol and computer keyboard events. You can
also involve any type of MIDI/OSC/network-capable controller, keyboard keys,
and/or 6 different types of random number generation to alter parameters of
a particular data conversion.
Actually, come to think of it, you might be able to do some of what you are
trying to do in 1 line...*
*Obligatory handicap: the only real nuisance with RTMix is that it's still
using the old /dev/midi junk, but you can alleviate that easily with the
virmidi module.
If interested, see tutorials for more info, and if that fails, please do not
hesitate to bug me ;-)

And course it was me: I always suggest Pd for everything, so don't
take me too seriously. ;)
I've never really looked into it, maybe now is the
time to do so.
I guess most of us started to learn how to do a bit of programming
when we wanted to do something specific, but nobody had already
written the tool to do it or we were dissatisfied with the available
tools. As you seem to be in such a situation, now seems to be a good
time to start to learn Pd or some other language.
