Incidental music for that rare occasion.
Descriptive warnings/pointers to inner meanings :
Part 1. Sunday morning, waking/dreaming/waking and dreaming again.
Part 2. Sebkha-Chott patiently teach GWAR how to tune their instruments
and play simple melodies correctly.
Part 3. An imaginary fretless bass dreams of 50s Darmstadt stardom, then
it all sadly fades away.
All sounds made by VST plugins created with Rory Walsh's Cabbage. All
instrument/processor designs by Iain McCurdy.
One non-Cabbage plugin was used, Martin Eastwood's MVerb, from falkTX's
DISTRHO-Extra code base.
Sequenced and rendered in Bitwig 1.2.0 (beta).

It's off-topic for the original thread and might confuse the OP of this
thread, so I opened a new one.
If somebody wants to get rid of pulseaudio, without recompiling,
without dummy packages, then it doesn't harm to test if software really
needs pulseaudio.

My Ubuntu install has zero dependencies to pulseaudio. Since I test a
lot with my Arch Linux install I need a dummy package to fulfil hard
dependencies for cinnamon and vice. There are 4 optional dependencies.
Even if I would like to use Cinnamon, I couldn't, because it requires
an absurd fast graphics. Using the "radeon" driver Google Earth is fast
as lightning, but Cinnamon is nearly unresponsive. Vice is an emulator I
just planed to test, but I never did, IOW assumed recompiling without
pulseaudio or just installing a dummy package, as I did, wouldn't work,
I could simply remove this software [1].
If users anyway suspend/kill pulseaudio and dummy packages work too,
then why is it a hard dependency for some software?
Why not using simply software that doesn't require pulseaudio?
I'm using openbox, but at least JWM, Xfce4 and Mate are installed too
and seemingly non of them requires pulseaudio.
If you're using a deb based distro, make a dry-run to test, if there
really is needed software that depends on pulseaudio [2].
IMO Ubuntu and Debian aren't distro for power-users or geeks only.

Hey,
Here's to all southerners for whom the so called Summer'15 didn't
made much sense...
Beg your pardon yet and again, but it's that time of year when
grapefruit is about ripening, pretty fast and maybe late, at least on
the northern hemisphere. No worries: harvesting has already been carried
away. So it's your call now, wether it makes for ugly bad wine or,
pretty good vinegar...

never mind,
Qtractor 0.7.1 (meson dope beta) is released!
Now, for the clueless:
Qtractor [1] is an audio/MIDI multi-track sequencer application
written in C++ with the Qt framework [2]. Target platform is Linux,
where the Jack Audio Connection Kit (JACK [3]) for audio and the
Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main
infrastructures to evolve as a fairly-featured Linux desktop audio
workstation GUI, specially dedicated to the personal home-studio.
And for the ones who can aptly tell a TL;DR apart from a hangover:
Besides the incidental bug-fixes and proverbial business-as-usual
stance for this dot release, the most probable and hopefully significant
news about it, is that this will the last to build against Qt4 by
default. The time has come to move on up to Qt5. Remember that a Qt5
build is and has been possible already for ages now but somewhat
relegated on a subpar status due to the once lack of support for all
non-Qt5 LV2 plug-ins GUIs out there. Not anymore! Starting from this
very release onwards there's this so called <em>native</em> LV2 GTK2 and
X11 UI support on Qt5. Also thriving, drobilla's libsuil is being
updated to par just that as well. So things are all aligning up nigh.
A special note to the voluntary packager: if you choose, for any
reason you may find commendable, to build, package and distribute a Qt5
build (via ./configure --enable-qt5 ...) please be sure that every LV2
plug-ins around that take Qt as its UI framework are also build,
packaged and distributed on the same premises, otherwise they might just
fail and crash Qtractor [1] on show. Among those are of course the one
comprised by the 'Vee One Suite', namely synthv1 [9], samplv1 [10] and
drumkv1 [11], of course.
Also as a(nother) side note: It has been for quite some time there's
an alternate github.com [7] repository which is kept in sync with the
sf.net one [8]. However, this doesn't mean that the Qtractor [1] project
is about to migrate to brand new hosting whatsoever: the original
upstream source code repository is, will be, as ever was, always kept
somewhere else still in this world and universe. It's a Git [12] world
out nowadays and as the mottos says, --everything-is-local,
--distributed-is-the-new-centralized ;)
Enjoy.

Change-log:
- Fixed an ages old MIDI track/channel instrument mapping (bank,
program) issue that prevented normal all-shut-up messages from being
sent to MIDI output buses/ports on playback stop.
- Messages standard output capture has been improved again, now in both
ways a non-blocking pipe may get.
- Fixed port on MIDI 14-bit controllers input caching.
- Fixed false value readings on the MIDI clip editor (aka. piano-roll)
tool-tips, when dragging a note velocity or controller value outside the
acceptable nominal range (eg. 0-127).
- Added LV2_BUF_SIZE__nominalBlockLength option support (patch by falktx
aka. Filipe Coelho, thanks).
- Fixed wrong initial tempo/time-signature display when session is
loaded from command line.
- LV2 plug-in UI GTK2 and X11 in Qt5 host native support added.
- Transport/Auto Backward feature now honoring (auto return) to same
current location precedence as Transport/Backward.
- Single/unique application instance control adapted to Qt5/X11 (cf.
configure --enable-xunique).
- MIDI Tools/Transpose, Resize duration display format (frames, time or
BBT) have been fixed.
- Build fix for Qt5.5 (patch by KaOS, thanks).
- MIDI Tools/Quantize et al. are tentatively being corrected to take
event times as relative to THE beginning of session, instead of MIDI
clip start location.

I'm looking for an audio switching application based around JACK.
Ideally I want a scheduler that will connect a JACK input to a specific JACK output at specific times during the day. Bonus points for HTTP interface for the scheduler.
Anybody know of anything like that?
Thanks,
James

I would like to get started editing a simple score and producing some
sound from it.
I have tried rosegarden recently but I can get no sound out of it. It
is far more than I require, as my confidence increases perhaps it is
what I will need but I simply cannot tell at this point.
In the past I have used csound, it has a less useful interface (suits
me) and is the closest to what I want but I need to get a colleague
entering a score and a text editor will not do.
I am at my wits end, what I might need is a beginners guide for
rosegarden, or better still a simpler programme, or virtual keyboard
(best).
I am completely swamped by all the options that I have and hence am a
bit paralysed. I can tell that whatever I choose will require a big
investment in time to learn but I cannot be sure that it is worth the
investment. And being unable to get any sound at all is very demoralising.
Worik
PS I have been doing a lot of sound recording and editing with Linux and
a M-Audio interface (usually) and a PreSonus AudioBox 1818VSL when I
have to mostly into audacity. When I am absolutely forced to (when
using > 2 tracks where Audacity cannot cope yet) I use audacious. I
find audacious endlessly irritating for the same problems I outline
above, so many options, so many knobs, where do I start? But audacity
pretty much just worked.

Hi list,
I am playing a http .m3u8 videostream with ffplay version 1.0.10 on
Debian testing and am getting drop outs about twice a minute, with the
following message being posted to the command line:
ALSA lib pcm.c:7905:(snd_pcm_recover) underrun occurred
This happes regardless of internet connection or used soundcard.
/proc/asound/card1/pcm0p/sub0/hw_params lists:
access: MMAP_NONINTERLEAVED
format: S32_LE
subformat: STD
channels: 18
rate: 44100 (44100/1)
period_size: 1024
buffer_size: 2048
I have not yet found a way to raise ffplay's playback buffers and would
be glad to hear about any ideas how to get to a more fluent playback.
thanks!

Hello all,
This qmidiarp release dares to come about a year after the last one...and yet
again: not much new stuff, but some more bugs squeeeezed, thanks to some
courageous reporters. And, after all, it's a lifesign isn't it? In other
words, updating is of course highly recommended.
Have fun with QMidiArp 0.6.2, below are the list of changes and links
Frank
-----
qmidiarp-0.6.2 (2015-10-06)
Fixed Bugs
o Arp: Regression: Latch mode caused the first note playing on
forever and other annoyances (Bug #12 reported by Alois Cochard)
o Seq: Small position error of the helper tick line relative to the
notes placed
o Seq: Note length values saved to file were not correct and had no
correct default (Bug #14 reported by Steve Grace)
o LV2 Seq and Lfo: Display was not correct when diminishing resolution
or length in plugin UI
Minor improvement
o LV2 Seq: Vertical zoom values are part of the controls and therefore
saved in presets as well
-----
QMidiArp is a MIDI arpeggiator, phrase generator and controller LFO for JACK
and ALSA. It can run multiple synchronized arpeggiators, LFOs and step
sequencers. The modules are also available as LV2 plugins with Qt user
interface. All in all it is a handy live tool.

the time being

I compiled supercollider to play through portaudio rather than jack, as it
usually does, in an attempt to reduce latency and hassle. It works for
audio device hw:0,0, but it doesn't work for hw:1,0. My problem is that on
my device hw:0,0 has horrible latency - 70ms - while hw:1,0 has 9ms latency,
much better.
So what I'd like to do is reorder the audio devices, or disable the onboard
audio, and have my current hw:1,0 be the hw:0,0 device. Hopefully then
supercollider will work with it and I'll have those coveted low latency
numbers. This is on arch linux on a bananapi armv7 computer.
So here's the output from aplay -l:
```
[bananapi@lemaker ~]$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sunxicodec [sunxi-CODEC], device 0: M1 PCM [sunxi PCM]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: Pro [Sound Blaster X-Fi Go! Pro], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
[bananapi@lemaker ~]$
```
According to the [alsa wiki][1], I should be able to reorder the devices
using a .conf file. See 'set the default sound card'. It gives the example
of this:
```
/etc/modprobe.d/alsa-base.conf
options snd_mia index=0
options snd_hda_intel index=1
```
Ok so I made a file like that, but I only know the name of the usb driver,
not the onboard sound driver. lsmod reveals the following:
```
[bananapi@lemaker ~]$ lsmod
Module Size Used by
snd_usb_audio 96225 0
snd_hwdep 5757 1 snd_usb_audio
snd_usbmidi_lib 18033 1 snd_usb_audio
cdc_acm 20518 0
spidev 6217 0
spi_sun7i 17802 0
sunxi_cedar_mod 9808 0
mali_drm 2608 0
drm 209226 1 mali_drm
mali 111427 0
disp_ump 861 0
ump 52415 2 mali,disp_ump
ap6210 584133 0
ip_tables 12937 0
x_tables 17443 1 ip_tables
```
If I do "modprobe -r snd_usb_audio", then snd_hwdep and snd_usbmidi_lib both
disappear too, so they are all for the same device I think. That leaves
nothing for the driver name for the onboard audio.
The alsa wiki says that the driver names should be in "cat
/proc/asound/modules" but I don't have that directory on my system.
So anyway I made an alsa-base.conf file as directed, which looks like this:
```
[bananapi@lemaker ~]$ cat /etc/modprobe.d/alsa-base.conf
options snd_usb_audio index=0
options sunxicodec index=1
[bananapi@lemaker ~]$
```
After creating that file and rebooting aplay just returns this.
```
[bananapi@lemaker ~]$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sunxicodec [sunxi-CODEC], device 0: M1 PCM [sunxi PCM]
Subdevices: 1/1
Subdevice #0: subdevice #0
[bananapi@lemaker ~]$
```
So this alsa-base.conf has the effect of making only the onboard audio
available instead of reordering. I most likely have the 'sunxicodec' name
wrong for the onboard audio, I'm just guessing at that, and have no idea
what the driver name for that is, if there even is one. I'm kind of
suspecting the audio device is part of a monolithic driver for the whole
system-on-chip, is that possible?
