Hello,
I'm trying to poll mixer events in Alsa using C. I've used the following
functions within an infinite while loop:
if (snd_hctl_wait(hctl,-1))
{
...
}
###### and
snd_hctl_poll_descriptors(hctl, poll_fds, 1);
err = poll (poll_fds, 1, -1);
if (poll_fds[0].revents & POLLIN)
{
...
}
While I can get the first mixer event fine, in all subsequent rounds,
both snd_hctl_wait and poll always return immediately.
With the snd_mixer functions one has to call snd_mixer_handle_events to
clear events. However, calling snd_hctl_handle_events here never returns
and I can't quite figure out why. Nonetheless, I'm not even sure that's
the key to my solution.
Can anyone give me some advice on how to get this working?
Kind regards, Maarten
Hi Tim,
Great update. Superb sound, and very tweakable!
Thanks for making this!
I have a similar problem as the one reported earlier:
In AmpVST, all amp-models sound the same to me except the BassMan.
Also: they all have a lot more gain/distortion then the BassMan.
This is with v 0.9.7.
If you want I can provide a small Ardour session to demonstrate the
problem.
All the best,
Bart.
I'm proud to announce the release of guitarix2-0.25.2
Guitarix is a mono tube amplifier simulation for jack, with additional
mono/stereo effect racks which can be filled with some in-build effects
as well as with external LADSPA plugins.
Download from http://sourceforge.net/projects/guitarix/
new in this release:
* add ts9 tube screamer simulation to lv2.plugs
* add dunlop wah / autowah simulation to lv2.plugs
* add booster /treble/low to lv2.plugs
* add factory settings file contributed by kokoko3k
* add patch by Brendan Jones to set (libgxw)library install path
* fix lv2 build on non ix86 arch (only use sse2 when supported by
build host)
* switch to use fixed block-size in zita-convolver for all lv2 amps
(hopefully fixed bug 5252 reported by prokoudine on tracker.ardour)
Please check it out and give feedback if you
find a problem.
Please refer to our project page for more information:

have fun

(I should have read this before responding to the first email...)
I just found a new issue with the BPM locking with v0.14.97, so I'm not
surprised at all if updating BPM from tempo sync got broken as well.
Getting this fixed will be a priority for v0.14.98.

Great!

Are there any specific sync/timing issues that you're trying to solve
by sending MIDI Clock messages?
MIDI Clock messages are currently ignored. Â The original MIDI enabled
version of phasex had this, but it ended up adding too much jitter to
the LFO frequencies and caused more problems than it solved. Â The
internal MIDI clock in phasex is used for timestamping incoming events
and assigning frame position. Â (Future plans include a more robust
tempo clock that can be used with MIDI Clock, MTC, MIDI triggers, tap
tempo, JACK Transport, etc.)
For now, the best options for keeping in sync with tempo changes are
JACK Transport Tempo sync or automating the BPM parameter. Â Not ideal,
I know... but this is better than nothing and should hold up until I
can get the tempo clock designed.

Artists of the Universal Music Group likely are members of the GEMA, even
if they aren't Germans.
If they catch you when smoking weed in Germany, the sentence isn't very
hard, but if they catch you playing copyright music of GEMA members you
are done. Some countries completely don't care about copyrights , but they
kill you if you're smoking weed. When in Rome, do as the Romans do!

Radium Compressor is the system compressor in Radium,
but distributed as a standalone jack application.
Radium Compressor uses the stereo compressor found in
effect.lib in the Faust distribution.
This compressor is written by Julius O. Smith III.
The GUI shows accurately the sound used for compression,
and how much the sound is being compressed.
I haven't seen this in any audio compressor GUI before,
but it's probably been done before.
