This problem is trivial, but maybe there's a trivial solution...
I have an Edirol UM-3EX USB MIDI interface that I sometimes pass through
to guest OS's in QEMU, which works surprisingly well at letting the
guest use the real world MIDI hardware.
However, QEMU does a reset on the device, which seems to cause it to get
a new USB device number and disappear from ALSA's view. If I physically
unplug and replug it, ALSA picks it up again and everything is fine, and
I don't even need to reboot.
It bugs me that I even need to do that. (I told you it was trivial.)
Is there a way to make ALSA scan for new devices manually? I'm on
Gentoo for what it's worth, but that may not matter. Obviously, ALSA
has some way of picking new devices up or else replugging wouldn't
work. I'm just thinking I should be able to trigger that myself, and
also it may be educational for me to learn how ALSA does this.

Hey hey,
I have noticed issues with liblilv for a while now. Upto now, it mostly hasn't
harmed me, but I suspect some other challenges I've had to result from these
errors. This is what I get:
lilv_world_load_bundle(): error: Error reading
file:///usr/lib/lv2/ProM.lv2/manifest.ttl
substitute the LV2 plugin of choice. I notice that with both Ecasound/Nama and
mod-host. I think lv2apply also printed that message, when I used it the other
day.
Could someone throw some light on this? Any helkp is appreciated.
Best wishes,
Jeanette

spectmorph-0.5.0 has been released.
Overview of Changes in spectmorph-0.5.0:
----------------------------------------
* Support user defined instruments
- graphical instrument editor
- new WavSource operator
* Make standard instrument set smaller (less download/disk usage)
* Graphical ADSR editor
* Added "SpectMorph User Manual" (online: html/pdf)
* Use different colors for active/used/unused operators
* LV2 now requires instance access feature
* Add file dialog wrapper shell scripts to work with some ardour bundles
* Integrate XML (pugixml) and ZIP (minizip) 3rd party code
* Minor fixes and cleanups
What is SpectMorph?
-------------------
SpectMorph is a free software project which allows to analyze samples of
musical instruments, and to combine them (morphing). It can be used to
construct hybrid sounds, for instance a sound between a trumpet and a
flute; or smooth transitions, for instance a sound that starts as a
trumpet and then gradually changes to a flute.
SpectMorph ships with many ready-to-use instruments which can be
combined using morphing.
SpectMorph is implemented in C++ and licensed under the GNU LGPL version 3
Integrating SpectMorph into your Work
-------------------------------------
SpectMorph is currently available for Linux and Windows users. Here is a
quick overview of how you can make music using SpectMorph.
- VST Plugin, especially for proprietary solutions that don't support LV2.
(Available on Linux and 64-bit Windows)
- LV2 Plugin, for any sequencer that supports it.
- JACK Client.
Note that at this point, we may still change the way sound synthesis
works, so newer versions of SpectMorph may sound (slightly) different
than the current version.

There are many audio demos on the website, which demonstrate morphing
between instruments.

Hey hey,
in tribute and honour to DJ Annie Mac I publish my new EP, with completely
fresh material: Congroovent
http://juliencoder.de/nama/congroovent
Happy birthday Annie, though for her it won't be for another hour yet.
This EP spans electronic genres from synthwave to club to drum and bass, with
80s synthpop, baroque music and modern harmonies in its gene pool.
>From the Linux side it involved Midish for sequencing and arranging, Nama for
recording/rendering to disk, processing, mixing and mastering, LinuxSampler
for opena dn commercial samples, including some self sampled and prepared
kits, Yoshimi - a happy birthday due shortly! - for some wonderfully unique
synth sounds and even Csound for the odd effect and creating/synthesizing an
IR for "Strain of thought", listen out for the snare!
Otherwise, yes it is heavily reliant on hardware, which is both for practical
reasons and a certain cult-motif. :) The practical reason being, from a sound
designer's point of view, the immediacy of programming, the accessibility for
a blind person, including the full depth of the instruments and, of course,
just having them. :)
I hope you enjoy it, I'd love to hear your feedback - good and bad - and you
are very welcome to share it. :)
Best wishes,
Jeanette

Hey hey,
I have just uploaded the drumkit, which I have sampled/created for the song
Chronophysis:
https://soundcloud.com/jeanette_c/chronophysishttp://juliencoder.de/sound/chronophysis_kit.zip
It is mostly self sampled, with a few exception: one kickdrum, - heavily
edited - taken from AVL drumkit, the "klick" taken from Klick, the advanced
JACK metronome, and the clap being recorded by a very good friend of his
youngest daughter Hanna.
The the heart and in/out I used my studio mic like a contact mic and applied
my larynx directly to it, with satisfactory results.
The kic and beep were edited/processed/part created in Csound. All other
sounds were recorded straight into Nama and processed there through LADSPA and
LV2 plugins.
Only the bell is missing, since it is a commercial sample, part of the Post
Bells library from PMI/Sampletekk.
Best wishes and keep banging your drums,
Jeanette

Here's one way to do it in Radium:
http://users.notam02.no/~kjetism/radium/pictures/2019-07-13_15-12-57.mkv
(sound is a little bit screwed up in the recording, for some reason,
but you get the idea)
Is this somewhat similar to working in RhythmLab, except that you drag
the length of sequencer blocks instead of changing the dragging the
"period" slider?
DrumGizmo 0.9.17 Released!
DrumGizmo is an open source, multichannel, multilayered, cross-platform
drum plugin and stand-alone application. It enables you to compose drums
in midi and mix them with a multichannel approach. It is comparable to
that of mixing a real drumkit that has been recorded with a multimic setup.
In this release we tried to jam in as many of our planned changes to the
xml as possible. There are still a few more to go but this release has
brought us a large step closer to our feature-complete xml format. Quite
a few other major features has also found their way into this release,
which will be much more visible (and audible) to the users.
Highlights:
Improved sample selection algorithm.
Clicky-kit feature.
Midnam support.
Directed choke functionality.
Drumkit metadata support.
Experimental Cocoa UI support for MacOSX.
Also some bug fixes and a lot of code refactoring (replaced eXpat with
pugixml for one).
For a detailed description of all the new shiny features, including
audio samples and lots of screenshots, see the changelog for 0.9.17 [1].
And now, without further ado, go grab 0.9.17 [2]

Hi!
In the gtk1 days, it was rhythmlab for experimenting with polyrhythmic.
http://www.panix.com/~asl2/music/RhythmLab/
Today, it seam possible to do it with ableton. Is it some native
GNU/Linux solutions for such kind of rhythms?
Cheers,
Dominique
