Hello all,
It has come to my attention that there are ATM at least two
'forks' of Aeolus. The first by the MuseScore team, the second
by one Maurizio Gavioli.
Neither of them even had the decency to let me know of their
work, and both are taking Aeolus in a direction I do not
approve of. Gavioli has even added his 'copyright' to the
sources of the libraries that Aeolus depends on but which
are not part of its source distribution. Apparently the
intention is to release incompatible versions of those as
well.
If this is typical for the attitude taken by the Linux Audio
community then my motivation to contribute to it will take
a serious blow.
As announced previously, there will be a fully reworked
release of Aeolus next year (on the occasion of its 10th
birthday). Apart from major improvements to the audio code
it will be completely OSC controlled. None of this will be
compatible with the forks of course, they'll find themselves
instantly obsolete. And I will make sure that this sort of
thing won't happen again, even if that means a more restrictive
license.
Ciao,

I've never had a proper go at Reason, but I know that Carla is a "rack"

along?

Jack uses ALSA; that driver code was tested only with Jack, and
expects the playback and capture streams to be opened at the same
time.

Even more bugginess. Maybe try the other Jack.
A patch series that should fix the bugs was posted on alsa-devel:

Huh? How could that work with JACK if it doesn't with ALSA?
Btw, this is what i get when trying to start JACK with it:

A monophonic real time note to MIDI converter. The main issue will be
different instruments will have different harmonic contents for the same
note, and this content can change with time especially during the attack.
That imply some kind of visualization of the signal will be needed to fix the
parameters of the algorithm for a given instrument. It will be a great
plugin/patch for Fons coming wonderful oscilloscope.

I fully agree. As the main fvwm-crystal developer, I know how hard it can
be to get good users returns. I find it scary if even developers cannot
share with each others.
I begun to write my own fvwm-crystal functions because I wanted them,
and when I was done, I contacted upstream. At first, I get no answer, so
I done a fork. Some months later, it was a discussion about my fork
on fvwm-crystal email list, and that time I get in touch with upstream,
and my work was incorporated into Crystal. Form there, I am now the
main contributor. It is not always easy, but so is life.
As the main fvwm-crystal developer, I just don't have the time to check
what can be the special requirements of each distribution or each user
that use it. And I find it very sad when they make modifications and
don't contribute them. From users, I can understand that very well, but
from developers, I think they just miss a very important point about FOS :
a community is always about solidarity.
That imply we must communicate more with each other. I think this is
a big problem, and not only related to Fons work, or the LAD, but to the
whole community. And it is not easy to solve if developers that make
patches just say nothing to the original developers. We are living
in an individualistic society, so are commercial softwares, but with
FOS, peoples must really take on them to communicate more about
what they are doing, that especially when they are making interesting
patches or forks.

Ralf, we already have good audio apps (non-timeline, etc), and it's easy
to port one to the other.
Qtractor doesn't do jackmidi.

Communication is the ground of civilisation. Unfortunately, our society
is so individualistic that some peoples miss it even when doing FLOSS.
It is why they have to learn to communicate at the first place. And that's
not that hard, it can begin by just sending an email.

Good morning
i'm trying to use a Roland R-26 as audio interface (USB).
I saw it is now officially supported in the alsa-driver repo log:
commit aa47d6014f7011b335345ce14836efe358b0cfe5
Author: Clemens Ladisch <clemens(a)ladisch.de>
Date: Sun Mar 31 23:43:12 2013 +0200
ALSA: usb-audio: add support for many Roland/Yamaha devices
Add quirks to detect the various vendor-specific descriptors used by
Roland and Yamaha in most of their recent USB audio and MIDI devices.
...
...
- Roland R-26 Recorder
So i cloned the alsa-driver repo (branch release) and run ./gitcompile.
Everything looks good and alsa force-reload worked.
$ cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.25.
Compiled on Sep 2 2013 for kernel 3.2.0-39-lowlatency (SMP).
When the device is plugged in and selected to act as an audio interface,
dmesg says (debug=verbose):
[ 5642.186130] usb 1-5.1: new high-speed USB device number 8 using ehci_hcd

[ 5642.394385] usbcore: registered new interface driver snd-usb-audio
$ lsusb | grep Roland

$ cat /proc/asound/cards
0 [R26AUDIO ]: USB-Audio - R-26(AUDIO)
Roland R-26(AUDIO) at usb-0000:00:0b.1-5.1, high speed
After compile, there is a clear warning:
WARNING!!! The mixer channels for the ALSA driver are muted by default!!!
**************************************************************************
You would use some ALSA or OSS mixer to set the appropriate volume.
-> alsamixer says "This sound device does not have any controls." so i
can't unmute anything there.
$ aplay a.wav
Playing WAVE 'rabe_babe.wav' : Signed 16 bit Little Endian, Rate 44100 Hz,
Stereo
-> there are no errors, but it stays like this (a.wav is a few seconds)
forever and there is no volume indication "from PC" on the device.
$ arecord -f cd b.wav
Recording WAVE 'b.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
-> no errors but the file is empty (44 bytes), the device shows active mic
level "to PC"
It doesn't work for input or output but i guess it's near working. The
only error is in dmesg (error -5 ?). Were could i go from here? Any hint
is welcome
Best regards,
Thomas
I was attracted by the small (memory and screen) footprint of JackMix, the Qt
Matrix Mixer for Jack, which makes it very useful on laptops, but needed to be
able to control it via MIDI. This lets us give performances at conferences
when we can't afford to talk the whole ensemble. We play a video along with the
live musicians feeding separate mixes to each performer and to master speakers
from multi-track video being played by the VLC Jack plugin.
Consequently, I've updated it to make the mixing elements respond to MIDI
control commands.
My updated version is here: https://github.com/nickbailey/jackmix
If the original author, Arnold Krille, is reading this, I'd really like to
email you, Arnold. There are one or two things I'd like to change but don't
yet understand the best way to do it!
Here is the NEWS file:
VERSION 0.5.0
-------------
New features this version (added by Nick):
The right-click on the matrix can be a bit fiddly to pop up the
context menu instead of the knob setting spinbox, so the following
shortcuts are now available:
* Toggle element selection with Shift-Mouse1
* Replace selected elements with Ctrl-Shift-Mouse1 in the upper-
left-most selected element
MIDI control of the mixer is now available. You can route signals
from a MIDI control surface to JackMix: it appears as "JackMix" in
the ALSA MIDI tab of QJackControl, for example. Each element now has
an extra context menu entry: "Assign MIDI Parameter". Use should be
self-evident.
Points to note:
* You can't unassign a midi parameter -- it can be set to
0 though (my control surface doesn't have controller 0;
some may I suppose).
* MIDI control parameter numbers are saved in the xml file
generated by File->Save File... menu action, but this means
there are extra XML attributes which might upset older versions
of JackMix. I've not tested this, but it might cause problems
if you aren't aware of the extra functionality.
