Hi, sorry for cross-posting,
I'm wondering which is the current status fpr the rtpMIDI protocol
suppurt under Linux.
As far as I know, there was midistream but is not maintained anymore.
Midistream was merged in a Scenic, but Scenic is a "huge" piece of software.
I need only rtpMIDI support.
There are some other solitions?
It would be nice if rtpMIDI, since it is a sort of stadard, will be
integrated directly in Jack (or ALSA?... humm, i think that rtpMIDI is
more a Jack thing).
What do you think about it?
I'm looking to setup something to take multiple inputs from a audio interface (say 8 channels) and then encode those inputs to several (MP3?) streams and send them to a icecast server for distribution.
I've used darkice/icecast on the same system with the built-in sound card (2 inputs), and now I want to ramp that up to say 8 inputs / streams.
I'd prefer this to be as close to real-time as possible, and all CLI/scriptable.
Qtractor 0.7.5 (hazy photon) is out!
It comes with one top recommendation though: please update, at once,
while it's hot! :)
Highlights for this dot/beta release:
* Overlapping clips cross-fade (NEW)
* MIDI Send/Return and Aux-Send insert plugins (NEW)
* Generic and custom track icons eye-candy (NEW)
Some other interesting points may be found in the blunt and misty
And just in case you missed it before,
Qtractor  is an audio/MIDI multi-track sequencer application
written in C++ with the Qt framework . Target platform is Linux,
where the Jack Audio Connection Kit (JACK ) for audio and the
Advanced Linux Sound Architecture (ALSA ) for MIDI are the main
infrastructures to evolve as a fairly-featured Linux desktop audio
workstation GUI, specially dedicated to the personal home-studio.
Change-log (since last tacky release):
- Beat unit divisor, aka. the denominator or lower numeral in the
time-signature, have now a visible and practical effect over the
time-line, even though the standard MIDI tempo(BPM) is always denoted in
beats as quarter-notes (1/4, crotchet, seminima) per minute.
- Fixed an old hack on LV2 State Files abstract/relative file-path
mapping when saving custom LV2 Presets (after a related issue on Fabla2,
by Harry Van Haaren, thanks).
- Default PC-Keyboard shortcuts may now be erasable and re-assigned (cf.
- New option on the audio/MIDI export dialog, on whether to add/import
the exported result as brand new track(s).
- Introducing brand new track icons property.
- Old Dry/Wet Insert and Aux-send pseudo-plugin parameters are now split
into separate Dry and Wet controls, what else could it possibly be? :)
- Brand new MIDI Insert and Aux-Send pseudo-plugins are now implemented
with very similar semantics as the respective and existing audio
- Implement LV2_STATE__loadDefaultState feature (after pull request by
Hanspeter Portner aka. ventosus, thanks).
- Plug-ins search paths internal logic has been refactored; an
alternative file-name based search is now in effect for LADSPA, DSSI and
VST plug-ins, whenever not found on their original file-path locations
saved in a previous session.
- Finally added this brand new menu Clip/Cross Fade command, aimed on
setting fade-in/out ranges properly, just as far to (auto)cross-fade
consecutive overlapping clips.
- source tarball:
- source package (openSUSE Tumbleweed):
- binary packages (openSUSE Tumbleweed):

I'm trying several things with pitch correction and shifting on vocals
these last days. It's for live purpose, and for rap music, so I've to
come to something with a rather small latency.
What I need is basically a pitch shift up to 1.2 and/or down to 0.8. If
possible, I'd like to get audible autotune correction as well. If
possible, also, I would like to be able to pitch farther from time to time.
AM pitchshifter gives interesting things, but I lose a lot of "sparse"
in the vocals when pitching down, so I'm trying to find something a bit
Autotalent gives good results in terms of sound, but the latency it
implies is simply out of question for live rap music.
VocProc doesn't work for my purposes.
zita-at1 is quite well, but I cannot shift from more than 2 semi-tones,
which is not really enough.
Have you other ideas?
Maybe I will try to patch zita so that it might shift more than 2
semi-tones, but I'm not sure it will work correctly.
Thanks a lot

Please let me know of any needed corrections, deletions, or items I
should add to the list.
This is a slow, short, quiet piece. Within are two opposite ways. One is
the base keyboard that goes up, and then down. This is found throughout
the piece. Up and down. On this, is the main guitar theme that weaves

I'm trying to use jalv & friends (or anything that can be scripted to
extract this info) to list my installed plugins by type.
I'm wondering how Carla and Ardour manage to sort plugins by type, like
instruments & effects, because when I look in the turtle files of the
LV2 plugins, it's unclear where this info is if at all?

This is a music video of a song recorded/mixed/mastered by me using Linux
(AV Linux 2016) with Harrison Mixbus 3.1 along with some Calf and linuxDSP
Plugins. This is also the first production from our new 'Bandshed' studio
and will be released as part of a full EP in a month or so. The band
'Evergreen' is the band my son drums in and 'Come Around' is an original
song written by the singer.
The video was not done with Linux tools and was a school project by two
film students related to one of the other band members, kudos to them on a
great job achieved with very modest tools!

Just a quick note here, to report success using the UB MADI with Linux
(Fedora 22, 4.4.4 kernel).
Doing some Ambisonics concerts in Bergen last week, needing 36 channels
output, the technician had set up DigiCo's UB MADI connected to the rig.
Everything plug & play: wiring the UB MADI to a usb-port, firing up
QJackCtl to look for hardware, choosing the found 'hw:MADI' from the
popup-menu, starting the server, and 48 I/O were available the rest of
that week :-) (i didn't use any of the inputs myself).
Bonus, we were 3 people running 3 computers for separate parts of the
program, hot swapping worked seamlessly during 3 days of heavy
rehearsals and concerts.
I just wanted to mention that the software sound module / tone generator
--works very well with Linux. I'm sure others in the LAU list are
already familiar with PianoTeq, but this is the first time I have used a
software tone generator to produce piano sounds in response to playing
my MIDI keyboard (a Yamaha CP5 digital piano), and I have been very
impressed with the results.
PianoTeq can use either ALSA or JACK (much lower latency using JACK in
my experience) and unlike some of the massive "ROMpler" (sampled)
software sound libraries that have been available for years, uses
complex and highly-configurable algorithms to model the sounds of pianos
(including some famous Steinway, Boesendorfer, and other current and
historical pianos), electric pianos, mallet instruments such as vibes
and steel drums, etc.
I ran the MIDI file of one of my pieces (Abstract 1) through PianoTeq
and produced a short YouTube video to demonstrate one of the presets for
PianoTeq's model of a Hamburg Steinway model D piano, here--
I'm already planning to upgrade my copy of the economically-priced
PianoTeq Stage to their Standard or Pro edition. An LV2 plugin version
of PianoTeq is bundled with the software, although I haven't tried it
yet. I was just surprised and very pleased that the software, available
for Windows, Mac OS X and Linux works so well in Linux (it does not
require WINE or any special configuration to work). It is distributed as
a very well (and beautifully) designed, highly-configurable and
feature-rich executable application that runs very well (so far, in my
experience) natively within Linux.
