All,
I guess the subject says it all. Anyone had any luck using it?

Could someone point me to some reference material to get MIDI
hardware up and running on my Linux system? I knew how to do this
just fine about 3 rev's of Ardour and 1 major rev of the kernel ago.
Unfortunately, all the documentation I'm finding is 7-10 years old.
I'm trying to figure out how to interconnect the *MIDI* of the following:
- M-Audio Delta 1010 hardware MIDI ports
- Mackie Control Universal hardware MIDI ports
- Alesis QS8 hardware synth
- a2jmidid software MIDI interface
- Ardour jack-MIDI ports
What can you folks advise?
Thanks...

PS:
A virtual MS20 or a real MS20 with a MIDI to CV gate interface?
wow. great ! thank you ! I use CPH a lot with puredata.
It will be great if it will be possibile to set up OSC host adress with
commandline options or so. Then it will be possibile to automate the
starting and connecting process.
cheers.

Hello dear linux audio users,
Having read threads about harmonySEQ, i decided to try it, then to
package it for ubuntu 14.04 as it is not included in the official
repository. As i also tested qtractor 0.6.0, i packaged it as well since
official ubuntu repository offers an older version.
I read the ubuntu packaging guide online, and finally succeed to submit
these two source packages on my launchpad personal package archive. I
thought these packages would be useful for some of you too if you are a
ubuntu user. These 14.04-only packages should be OK to install on any
ubuntu 'trusty' flavour. If you like qtractor or harmonyseq, and use the
latest ubuntu, you may be interested in adding the PPA into your APT
configuration. See details on 'howto' here:
https://launchpad.net/~brouits/+archive/ppa
Actually, its just a matter of blind typing 3 comands in a terminal:
$ sudo add-apt-repository ppa:brouits/ppa
$ sudo apt-get update
$ sudo apt-get install harmonyseq qtractor
(do not type the '$')
These _unofficial_ packages have been built for both 64bit and 32bit
Intel platform.
But BEWARE, these packages are for ubuntu _14.04_ only. Do not install
them on an older ubuntu version.
If you have an older ubuntu, you might want the source package: i can
give you so that you can build it on your version.. if it works.
Qtractor has been compiled _without_ Windows VST support (cause i do not
have the Steinberg vSt sdk, which needs a registration on the Steinberg
website), and linked against Qt4 gui library (QT5 version gave weird
menus on a Unity desktop).
HarmonySEQ is just as is, no special enabled or disabled features.
Thanks to the authors of these cool softwares.
Cheers, and happy composition.

I gave it a royal tryout just now. Below is sound-patch startup code, it's actually a mashup of most of my START-INITIAL script which runs at boot, and the first patch script which it calls. When I keep the schedtool prefixes, MIDI keyhits all make it in and synths all get their signal out through the sound card output. When I don't, about one in 20-30 keyhits (and also occasionally key-ups) get lost, and there are cutouts both at high load and very low loads. Some may notice I have let the latency rise to 4; this too seems to be indicated for the loads I'm using, though if I were using just one light load (say, a simple Yoshimi patch), it could be ratcheted down a lot. Oddly, it does appear that a different patch which calls just Fluidsynth, functions as a heavier load than three Yoshimis; it is true that Fluidsynth is itself using a rather big four-voiced soundfont. I have another which right now is two Yoshimis plus the same Fluidsynth an octave lower (octave handled by mididings), that one is higher yet, but the setup and weights below are handling it well.
The relative weights are definitely guesses based on behavior. I just increase the weight of anything which misbehaves, until it makes it worse, then reverse :-) I did find earlier tonight that I had neglected my limits.conf, so this is what I have set now, which allows those numbers below to actually work:
@audio - rtprio 95
@audio - nice -19
@audio - memlock 512000
I'm not sure the nice is at all needed, but it doesn't seem to be harming anything.
