Hello all, A friend of mine, who is mainly a Windows user and has limited knowledge of Linux, has two HP laptops running Archlinux. One of them works perfectly with an RME Octamic-XTC. The other doesn't seem to detect it as a sound card (it doesn't show up in aplay -l). On both the RME is recognised as an USB device (by lsusb). I'm trying to help him fix this (remotely). We compared kernel and alsa versions, they are the same. In fact the two Linux installations should be identical, both had a full update before I shipped to two laptops to him. What could be the problem on the second PC ? TIA, -- FA

[LAU] [ANN] Qtractor 0.9.29 - An Early-Autumn'22 Release batch #3

by Rui Nuno Capela

Hello there, one third and last time, Qtractor 0.9.29 (early-autumn'22) is released! Change-log:: - Capture same time(stamp) note-off tracking and postponing is now on trial, hopefully mitigating a legato issue, reported to MIDI wind instruments (EWI). (EXPERIMENTAL) - Fixed an old window parenting (aka z-level) issue, related to the Add Track and Track Properties dialogs and whether called from the main or mixer menus. - Fixed the out-of-process plugin scanner terminating too soon and sometimes miss some very last results. - Fixed another old bug in MIDI note-off messages not being sent while playing after a loop region. - Fixed a pretty ancient bug in the VST(2.x) plug-in program names inventory, present when building to the VeSTige header (which is still the default). Description: 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.

[LAU] [LAA] XUiDesigner v0.8 released

by Hermann Meyer

XUiDesigner v0.8 released A easy to use tool to generator/design X11 based LV2 Plugin Bundles. Beside that XUiDesigner allow to generate and install GUI's for existing LV2 plugins (so far only Reaper fail to load extra UI's), it support as well to generate LV2 plugins from scratch. Special support is implemented for FAUST dsp files, which allow you to generate a LV2 plugin with X11 based UI by just drag'n'drop a FAUST dsp file into the XUiDesigner interface. This works now as well for MIDI capable faust modules. In any way, you don't need to interference with any of the annoying LV2 implementations. XUiDesigner handle that all for you. The very same is true when you like to implement your own dsp (C++) into a LV2 plugin. Example files for how to create a c++ file for parsing (drag n' drop) with XUiDesigner been included. For later rework the UI a json file will be created which you could drop later on XUiDesigner to load and rework the UI. This may also be usable by other toolkits to create a UI? This release comes with a couple of Bug-fixes and aims to be nearly stable. Here is a introduction Wiki <https://github.com/brummer10/XUiDesigner/wiki/XUiDesigner> entry to show the first steps. Note: Please download the attached XUIDesigner_0.8.tar.gz <https://github.com/brummer10/XUiDesigner/releases/download/v0.8/XUIDesigner…> archive, as only that contain the needed git submodule ( old long time knowing bug on github) as the other files wont be able to build XUiDesigner for you. New in this release: Implement Virtual Midi Keyboard Widget Fix segfault under Wayland Fix several Bugs Implement proper *.cc file parser Add examples for *cc file parsing Project page: https://github.com/brummer10/XUiDesigner Download Release: https://github.com/brummer10/XUiDesigner/releases/download/v0.8/XUIDesigner… Enjoy anyway.

[LAU] LinnStrument on Linux

by Thomas Poulsen

Dear list, I recently bought a LinnStrument from Roger Linn Design: http://www.rogerlinndesign.com/linnstrument.html It is a great isomorphic midi-controller, and as such it is immediately recognized on Linux. The distinguishing feature of the LinnStrument is that it senses 3 degrees of freedom on each note: x-direction, y direction and z-direction (pressure). The x-direction is mapped to pitch-bend, and y-direction to CC74. A cool feature is the "slide", where the pitch-bend is used to slide between all notes in a row. To allow individual pitch and CC74 values for each note, it sends each note on a separate midi-channel ("MPE"): http://www.rogerlinndesign.com/implementing-mpe.html Bitwig has added support for this, and there is 20 presets in version 1.3.11, where this is used (tag: linnstrument). The LinnStrument controller is not recognized automatically on Linux in version 1.3.11, but it can be configured manually, and then it works fine. Note that both midi-in and midi-out has to be configured, if not there is no sound! It should look like this: https://ibin.co/2msBJVgpKtf9.png Now I would like to also use it with the free Linux synths. Here's what I have been able to make work this far. Synthv1: PME works reasonably well: I can play polyphonic in MPE mode, but it tends to miss the "note off"s. I can get the slide to work, by setting <param index="36" name="DEF1_PITCHBEND">2</param> <param index="78" name="DEF2_PITCHBEND">2</param> is a preset. Zynaddsubfx: I can not get MPE to work. Sending only on one channel, and setting PWheelB.Rng to 2400 cents, I cant get the sliding to work, but only when playing with one finger. If I enable MPE on the LinnStrument there is only an occasional sound, when it happens to send on the channel, that Zyn is listening on. I'll love to hear if other LinnStrument users have been able to do more with any of the free synths on Linux. All the best, Thomas

[LAU] [music] Going rascal

by Jeanette C.

Hey hey, this is a very energetic, driven rock/prog track. https://youtu.be/H0qAu1U9U3o OGG version: https://www.dropbox.com/s/z19uw7ksqlf0nrp/going_rascal.ogg I had this theme lying around for ages. It seemed too good to just get lost at the back of the sofa. So I rerecorded it from scratch. In terms of sounds it's mostly in excercise in analogue, subtractive synthesis and patching on my Behriinger Neutron. The drums are Drumgizmo with the Aasmonster kit, which I love a lot. More difficult to edit, but it brings a lot more potential for shaping. Especially the drums took a lot of shaping and processing from simple filtering, EQ'ing and compression to creative processing. :) Hope you enjoy it, have a great Sunday!

[LAU] How I built my own IR reverb in ambisonics

by Michael Jarosch

Hi! Don't know, if this is actually the academic or scientifically correct way to do it, but I got good sounding results - in fact, I managed to insert mono-recorded voices into an ambisonic recording with other people and it didn't sound that weird… But I'm always interested in getting things more and more perfect, so I hope many of the ambisonics-pros are joining this thread to discuss the topic. This is the software and hardware I used: * Røde NT-SF1 1st order Ambisonics microphone * Sound Devices MixPre-6 recording device * Ubuntu Studio 04.22 * Carla 2.4.2 * Røde Soundfield PlugIn (Windows 64bit VST3) * Wine * Ardour 6.9 * Audacity 2.4.2 * LSP-PlugIn Suite (LV2) * IEM Ambisonics PlugIn Suite (LinuxVST) And here is the whole procedure, how I made it… I made an ambisonics recording with people in a room. After that I took a paper bag to create an impulse, about 50cm away from the NT-SF1. (Just clapping the hand was too silent in my opinion and I didn't want to use balloons because of the plastic waste. Paper bags seem to be an relatively environment friendly and cheap alternative to me.) I retried as often as it needed to get a good sounding and non distorted record of the impulse and its respond. Getting back to home I copied the A-format of my recordings to my computer, fired up Ardour, created a 4-channel track and inserted the 16-channel-version of carla patchbay into that channel strip. I had to deactivate the panner in every channel strip to make Ardour "ambisonics compatible", yes, also in the "Master"-channel which must be blown up to 4 channels, too. I imported the tracks that I wanted to be converted. The only tool in my procedure that wasn't free and open was Rødes Soundfield PlugIn, so I had to use some tricks to get manufacturer proven A-to-B conversion of my recordings. FalkTX did make carla windows-VST-capable, but it's not a bullet prove task… So, I got the Soundfield exe-file, installed it with wine and I finally got a dll I could drag and drop into carla patchbay's GUI. There it is! Chances are Ardour crashes, so I made sure to save after every step. As input format, I have to chose "NT-SF1", on output the best choice is to use "B-Format (Ambix)", because Ambix is the actual standard and the IEM plugins only handles Ambix. Of course, I had to connect Carla's output to the input of Soundfield and vice versa. Time for the A-to-B-convertion. Drag and drop the 4-channel-audio into the editor window of Ardour, set "Start" and "End" and use export. Make sure to have all 4 channels to be exported into one file. You can use both WAV or FLAC. Next step is Audacity. (You don't need to close Ardour, sooner or later it will crash… :) ) Instead of stereo files, Audacity handles 4-channel-audio as 4 seperate mono files. (But it can be exported to 4-channel-audio, again, if you choose "advanced mix options" in the "import/export" division of the preferences. You won't need it for the virtual ambisonics IR reverb.) But - it is mandatory to keep the audio sample accurate between all the tracks! If you want to delete, delete from all of them, simultaneously! So, you choose your favorite BANG! out of the inpulse series you recorded and delete the rest. Export every mono track as WAV. Use Ambix nomenclature: 1st track is W, 2nd is Y, 3rd is Z and 4th is X. Best bet is to write the number and the letter in the name of the file. I choose: [nameoftheplace]_1_(W).wav and so on… Now, to actually build the virtual ambisonics IR reverb, fire up Ardour and make it ambisonics compatible (deactivate panner). Create a 4-channel-audio-bus and place a 16-channel Carla patchbay. In the Carla patchbay, create 4 "LSP Impulse Responses Mono" - one for each channel. (Using LV2 in Carla works pretty stable!) Open the GUI for each "LSP Impulse Responses Mono" and use the corresponding WAV in it by clicking into the GUI and choose the right file. Inside Carla patchbay it should look as follows: Carla channel 1 output ---> LSP Impulse Responses Mono #1 (with [nameoftheplace]_1_(W).wav) ---> Carla channel 1 input Carla channel 2 output ---> LSP Impulse Responses Mono #2 (with [nameoftheplace]_2_(Y).wav) ---> Carla channel 2 input Carla channel 3 output ---> LSP Impulse Responses Mono #3 (with [nameoftheplace]_3_(Z).wav) ---> Carla channel 3 input Carla channel 4 output ---> LSP Impulse Responses Mono #4 (with [nameoftheplace]_4_(X).wav) ---> Carla channel 4 input Make sure, that every LSP IR Mono instance uses exactly the same values of headcut, tailcut and amplification. WIth headcut, you should cut the impulse. Now, you can use a mono audio file, place it into the ambisonics sphere f.e. with the IEM StereoEncoder, use an auxiliary send (don't forget to disable the panner of it, too!) and enjoy the reverberation! (Play with Ardour's "strict E/A" to get as much channels for each strip you need!) Using an EQ after the virtual reverb is always a good idea. LSP IR Mono has one integrated, but my impulses seem to have no linear frequency band and needed more than the +/-12 dB the plugin offers… (I take IEMs "MultiEQ" for this task - one setting for all the channels is another advantage.) Unfortunately, Carla can't recall LSP IR Mono's WAV-file, so, you have to reload it, every time you start your session. Greets! I hope, this can be useful for anyone… Mitsch

[LAU] An oldie revisited

by Will Godfrey

I sort of found an old track of indeterminate age, and thought I'd like to try a remix, so looked for the project folder. It wasn't there! That was a bit of a shock, as I never delete these, so how it came to be missing is a mystery. It would have been possible to keep listening to the original audio to (slowly) piece it together, but that was more tedious than I fancied. At this point I didn't know just how old it was - the audio had a file date in 2010, but I suspected it was older. Eventually I remembered I had a compressed archive of my very early pre-linux work, and there it was! Well, it is a not quite kosher MIDI file. This has the last modified date in 1994, so indeed older than I though. Importing it into Rosegarden produced a lot of strange bits of tracks separated from the actual notes, and no sign of track names, but it was enough to get started. That was about a month ago. I now have the entire recording, expanded and reproduced with Yoshimi (the original would have been a mix of Sound Canvas and SY22). So here it is. Personally I find it quite difficult to keep still while it's playing :) https://soundcloud.com/soft-sounds/skipping-rope -- Will J Godfrey {apparently now an 'elderly'} https://willgodfrey.bandcamp.com/ http://yoshimi.github.io Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.
