Linux Audio Monthly Round-Up #6 - January 2011

Dear all,

The holiday season is over and I actually took advantage of it by not working on this month's round-up but by making music. With the help of Leigh Dyer's outstanding seq24 tutorials I'm trying to master seq24 and so far I'm really enthusiastic about this sequencer. I've started remixing an older track of mine and seq24 has already proven itself a very valuable tool.

But I did read up on relevant mailinglists and forums to keep in pace with the developments in Linux Audio Land. And December did yield some interesting topics, like the RT_GROUP_SCHED option (cgroups) discussion on the Jack-Devel mailinglist and the refutation that CPU frequency scaling has no use for low-latency real-time audio, and then there was the sheer amount of music made with Linux of course!



PS. Thanks to the people from LinuxMAO, without them I'd miss out on a lot of developments, releases and other non-trivial events worth mentioning!

Linux audio news

December was a bit quiet news-wise but it wasn't quiet at all music made with Linux-wise! A lot of musicians were very active and published one song after the other, like Modlys, Julien Claassen or Visio from France. But a lot of separate tracks were released also adding up to quite an amount of enjoyable music made with Linux this month.

The biggest topic was of course the cgroups discussion on the Jack-Devel mailinglist. For a few years Linux audio users have benefited from a relatively easy way to set up their systems for real-time low-latency audio processing and music production but chances are setting up such a real-time environment might become a bit harder in the near future. More details on this issue are spread over several threads on the Jack-Devel mailinglist and an article on the JACK site.

It had become a bit of a common ground in the Linux audio world, if your CPU supports frequency scaling you'd disable it from scaling and set the CPU's frequency to a fixed governor to prevent any xruns from occurring. But this has drawbacks of course, especially on mobile set-ups without any power output nearby. Running your notebook or netbook with the scaling governor set to performance empties the battery a lot faster and yes, you could set the CPU frequency lower or use a scaling governor but then you might run into xruns when the DSP load peaks or increases. The discussion on this topic inspired Robin Gareus to develop a specific JACK dependent CPU frequency scaling daemon, jackfreqd.

Music made with Linux

You know what? I just came to realise that there was simply so much released in December that I'm going to dedicate a separate entry to it! So expect an overview in the beginning of next week. This will also not further delay the publication of this round-up. I'd like to listen to the 30 or more tracks a bit more extensively instead of skipping them through quickly. They deserve some more attention.

- Add extra checks to detect when param_count != param array size – 1.
- Fix another install-related crash, this time due to invalid params in fluidsynth.
- Fix the infamous crash on install.
- The range given in the comment wasn't really correct.
- Use symmetric dB range for EQ plugins.
- Fix a few bugs in compilation of limited versions (DSSI without GUI, no JACK host).
- Initialise the vintage delay properly... hopefully this time.
- Unbreak Monosynth by changing listview to use a 'key' attribute instead of 'param'.
* Refreshed French QM file
* For some reason the "lrelease" utility produced an incomplete QM file.
* Releasing from within the Qt Linguist seems to work.
* Updated French localization files. Thanks to Bernard Opic <bernard/dot/opic/at/media-tips/dot/com> for the contribution!

* Added a one-window-mode which allows to have only one instrument track window open at a time. The content of this window is replaced each time you open a different track.
* Furthermore added global reception and forwarding of key events to the piano widget of the top-most instrument track window. This for example enables the user to play test sounds while tweaking some effects in a different subwindow.
* Fixed alternating row color in QTreeView (Sf2 patch selector)
* With Qt 4.7 the alternating row color in the Sf2 patch selector dialog somehow was messed up. Fixed this by explicitely setting the alternating row color in the style's CSS files.
* SampleTrack: do not hide EffectRackView forever when closing subwindow
* Whenever closing the sample track effects window using its own close button and trying to open it again there was only a really small windowwithout functionality. Fixed this by explicitely also showing subwindow content in showEffects(). Closes #3075205.

December 23: Bristol 0.60.8
* Made some changes to the way bristolrc is handled. If the file exists then a seach is made for two tokens, PREARGS and POSTARGS. If they don't exist then the same default behaviour takes place: all the contents are concatenated into a set of options that are inserted before all the user parameters. If either of these tokens are found then PREARGS are inserted before the user parameters and POSTARGS are appended to the whole net commandline to the GUI and engine. This gives a lot more flexibility to override default behaviour, for example:

PREARGS=-count 1024 -rate 48000

POSTARGS=-jackstats -jack -multi 0

Using such contents then the command 'startBristol -mini' would be expanded to

startBristol -count 1024 -rate 48000 -mini -jackstats -jack -multi 0

A part of the reason for the above change was that there were reports of issues with the ARP 2600 and period sizes less than 1024. The culprit appeared to be the -multi option, this defaulted to 4 for the 2600. Changed it to default to zero with a need to then explicitly reconfigure it. The reconfigure can now be automated in POSTARGS. The diverse Bristol front end appliations such as monoBristol provide user arguments to the startup script, the current bristolrc definitions can provide capabilities to extend how they operate as there are now pre and post arguments that encapsulate the frontend parameters.
* This release is noted as including hammond optimisations, these are not with respect to CPU load, rather with respect to accuracy of the emulation:
- Adjusted the B3 Preacher Compression code to provide a more pronounced non-linear amplification. The results are interesting/different. It mixes well with the new gearbox generated for a clean tonewheel (mostly sinewaves with no crosstalk) and a mild crosstalk gearbox with some sliced tonewheel harmonics. The control is not continuous, there are 3 stages which are selected as the rotary changes position, this would normally be represented with radiobuttons however the GUI previously only had a rotary control so this was used to prevent a big reordering of the options panel layout.
- The new tonewheel gearbox are in the factory shadow profiles, per default as below. To test them then copy the target gearbox to your private memories (these are the defaults, your installation may be different):

source: /usr/local/share/bristol/memory/profiles/tonewheel*

dest: ~/.bristol/memory/profiles/tonewheel

- Also made few alterations to the B3 VC algorithm changing the tap gains and LC filter values, altered the tap selections for the different 1/2/3 settings and adjusted the selector mode to reconfigure LC and phase (which work in combination) rather than the actual tapping points. More work could be done but these do now give some different characteristics where previously VC3 was the only useful setting. [Note: it would actually be quite easy to make even further improvements here by using an alternative filter algorithm into the different taps. The current one is a rooney which has weak phase modification, it is similar to the original in as much as that could only introduce about 1ms of phase change however bristol has other algorithms that would give better phase changes by frequency which would be closer to the Hammond vibra. The current code overcomes the rooney limitation by taking the phase changed filter signal (which has a phase change that is dependent on frequency) with an additional phase change that is time constant. The issue is efficiency, the rooneys are single pole and come almost for free. Ffs]
- Reintroduced some B3 code to give contact delays for each drawbar. The delay is configured in the tonewheel file and is then a function of velocity. The tonewheel file defines the maximum sample delay before any given harmonic is activated and this delay is reduced depending on velocity. It is also possible to configure a click sample per bus out of 4 available however the author will state that none of the samples is accurate: click, thump, shelf, etc, is not an accurate emulation. Depending on which source is considered authoritative then the Hammond click may be a pure function of tonewheel position and its activation point. This code emulates that effect with the option of adding in extra effect as a combination of the tonewheel file samples and the overall click setting. Note that the 'click' level does not affect the cut in points of the harmonics, reducing the 'click' level will not affect the tick sound when a drawbar contact is finally made. The harmonics do not have a constant phase (as per the original) however the tonewheel file can override that to emulate the L and M series spinets. With the current code, pressing a key very slowly should result in the delays between the different busses being almost audible, an effect that reduces with velocity. The configured Click is reduced when the vibrachorus is on as is also heard on the originals. This is partially due to parameterisation and partly due to the filtering effect of the vibra-chorus.
This click code has actually been available for a few years, it was removed as it affected other developments for gearbox optimisation. This optimisation was to 'post generate' the tonewheels: if a harmonic was not needed then it would never be generated. This was not condusive to busbar delays so now the decision has been taken to drop the CPU optimisation in preference of a more accurate rendition. At the same time the tonewheel damping was corrected so that, under control of the Damp option, the summed levels of any given wheel is not linear but is a function of the number of times it is tapped. It is noted here that if no click is desired, at all, then the 'preacher' algorithm should be disabled at which point notes are generated from zero point as per many of the commercial emulators. Several of the later Hammond models reduced/eliminated key click using various techniques, disabling the Preacher would give results closer to the B2XX series organs. Disabling the preacher removes the damping, busbar offsets, and all the other features of the tonewheel file.
Adjusted the click code to introduce changes to the bus offset delays by key as well as velocity. The existing code used a single profile per gearbox but no two keys would have had the same contact profile as this was based on aging of the springs: the code now has semi-random delay selection. The 'semi' refers to code that will select the same relative offsets if the same key is sounded sequentially, adjusted by velocity still: this is how Jimmy Smith used to play key click with the same key - now the delays for that sequential key do not change (they will if intermediate notes are sounded which he also did and potentially the delay offsets may be prebuilt for the whole keyboard rather than calculated, ffs). The different bus delays only affect timing not the actual effect so if 'Click' is non-zero then the sample selection per bus will be constant even though the delay changes. Now, another affect of the bus delays is that if playing quickly it is possible that a note will start and stop before even all the harmonics have sounded, this is another trick of Smith when he played notes to not traverse the complete travel of the key: not all harmonics would actually make contact and this is also possible with bristol (depending on velocity, buffer size and configured bus delays).
* Added a -keytoggle flag, it affects GUI behaviour where a key is released when the mouse button is released. Previously the key state latched which was useful for polyphonic emulators but not necessarily for the monophonic ones. The default operation is now not to latch the keys, this option overrides the new default behaviour to give latching keys again.
* There were some sticky keys and note 'ticks' when using the monophonic synths with -nnp (no note preference). The polyphonic note logic could completely kill notes when overvoice and if a keyoff event occurs for a voice on the new list then some of the flags would get damaged. None of this happens with monophonic note preference or with polyphonic synths (well, the ticks may still happen if the polyphony is exceeded but get burried in the mix of multiple voices, ffs).
* Bug report on some emulators defaulting to only one semitone of pitchwheel depth. This turns out to be emulator aliases: the interface recognises some alias names but it could not set defaults except on exact names. Incorporated some changes to accept the known emulator aliases too.
* Feature request that the SID should acknowledge pitchbend wheel as well as or instead of pitchbend on the modwheel. Not a big change and the issue with the MOD wheel is that it was difficult to tune having no notch. Currently both controls can affect pitch but the modwheel can be turned on/off selectively.
* There was a window when the global configuration options would not be sent to the engine, a race condition. The result would be no output signal.
* There was another race condition in the GUI library which for now has been patched. The actual fix is a little larger but it will be left for future research.
* Found a bug in the MIDI handling code for NOTE_ON velocity zero being mapped to NOTE_OFF velocity 64. When the ringbuffer was introduced the check moved to the wrong side of the ringbuffer causing an endless loop at 100% CPU, for some emulators quite a lot of nasty random noise and potential system 'hang' for certain CPU configurations with RT scheduling. This had not been reported which means either people did not bother or the use of NOTE_ON velocity zero is not widely used.
* Release 0.60.7 had an undocumented feature, undocumented because it was not that big but it did go into the manual page. The option -jackstats will prevent bristol from attempting to find out the current jack server settings, these parameters would instead be defined with -count and -rate. This change fixes some issues with jack connections, with LADI, and makes the GUI start a bit faster as it does not have to poll the server from the script then reconnect to the server from the audio thread.
* The BME-700 Glide on/off switch was not active.
* Roadrunner Vibrato was too deep, by a long way. Scaled back the tremelo at the same time. Gentle vibrato was still possible but not under mouse control, it had to be done with keyboard accel/deccel.

December 28: jack_freewheel_button 0.2 NEW!
* This button allowes to free/unfree jack time wheel or just monitor freewheel state
