[LAU] Steinway_IMIS2.2 soundfont (no loops fix)

by Roberto Gordo Saez

This is Steinway_IMIS soundfont, version 2.2. ftp://musix.ourproject.org/pub/musix/sf2/Steinway_IMIS2.2 This version fixes the issue with loops. I hope this is the good one and there are no more remaining major bugs. Marcos is a little busy right now, so he asked me to make this fix. He is thinking to make other improvements, so expect more updates soon.

[LAU] Raspberry PI and PISound

by worik

Is anybody out here in LAU land have experience with PISound? https://www.blokas.io/pisound/ I have just bought one and am having quite sever teething problems with it. It keeps freezing for ~45 seconds when running X and I cannot get it to use the full display. cheers Worik -- If not me then who? If not now then when? If not here then where? So, here I stand, I can do no other root(a)worik.org 021-1680650, (03) 4821804 Aotearoa (New Zealand)

[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] JACK and Sound OpenFirmware?

by Mario Lang

Hi. With kernel 5.7, my system finally switched over to snd_sof_pci for the intenal card. I can use mpv and alike via alsa directly, but when I try to start JACK I always get the following message: ALSA: cannot set period size to 1024 frames for playback Adding the verbose flag to JACK doesn't make it any more informativ regarding this problem. With the old hda driver, JACK was perfectly working with a buffer size of 1024 (and less). Does anyone know what I can do to make JACK work with the internal card? Or at least how to debug what is actually preventing it from working? I am using a Lenovo X1 Carbon 7th Gen. -- CYa

[LAU] Hardware timers?

by Roger

I'm just experimenting with new setups of Debian for audio. When running RealtimeConfigQuickScan it triggered a vague recollection of a discussion (here?) that configuring hpet and rtc timers is no longer necessary as they are not used any more. Is this true or am I misremembering? The wiki guide at https://wiki.linuxaudio.org/wiki/system_configuration is still a goldmine for setup but it contains some sections of which I am unsure whether they are still applicable, including the HW timers bit. Cheers Roger

[LAU] [OT] Future of Music Distribution (and examples?)

by Andrew A. Grathwohl

Hello Linux Audio folks! I wanted to see if I could get a conversation going about the future of music distribution. Given that we are people who make creative works with free software, I figured this is as decent a place as any to discuss what is out there, what is possible, and what should be avoided. My own personal approach to distribution is detailed below, but I invite others on this list to share their own methods and ideas. By now, most of us are probably resigned to the fact that the music world will look quite a bit different going forward, compared with prior eras. Many musicians feel that today's points of engagement with music fail to provide adequate revenues, and are taking to social media to criticize Spotify and the ilk for not being better "stewards" of music. I largely agree with those sentiments, which is why I have been taking the opportunity to construct a solid home base for my music project <https://multipli.city>, which is fully operated on my own physical hardware and some AWS cloud services at a cost of $7/month. It's just a simple jekyll template <https://github.com/SacredData/pRoJEct-NeGYa> hosted on GitHub Pages. However, by publishing my music releases to my own jekyll page one time, I get the added benefit of also publishing to all desired locations on the web simultaneously, including to a podcast feed <https://multipli.city/podcast.xml> compatible with Apple's podcast network. It's weird to me that we are still trying to unit-price music in a world where it's cheaper and easier than ever to record, produce, and distribute it. I am not necessarily interested in profiting from my own musical endeavors, but a friend of mine is a rather popular independent electronic artist, who has pointed out to me that despite millions of annual streams, streaming services alone don't provide him anywhere near a livable income. In my opinion, this shouldn't be so. There's also the issue of being beholden to the whims of private firms who run various online music services. Anyone here miss SoundCloud Groups, for example? I've begun to wonder if solutions like mine could be the foundation for a new kind of music distribution approach - perhaps one where musicians maintain podcast feeds, where monetization vectors are much more profitable and much more flexible for individuals to exercise without betraying their own values.

[LAU] [Music] Garden realities (3d soundscape)

by Jeanette C.

Garden Realities is a 3D binaural soundscape or sonic world, based entirely on field recordings of summer birds, with rather subtle processing. https://youtu.be/FfMo_2ZO7_8 To get the full effect of this piece, you best listen to it on headphones and try to sit rather still. The piece was entirely realised in Csound, using the HRTF opcodes/modules for spatial placement and movement. Some field recordings, the chicken in particular, were contributed by my favourite Motzhuhn. :) I hope you get taken in (and maybe away). Best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * SoundCloud: https://soundcloud.com/jeanette_c * Twitter: https://twitter.com/jeanette_c_s * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c Ain't no way I'll be lonely <3 (Britney Spears)

[LAU] [Music] Cloud Castles (melodic Drum&Bass)

by Jeanette C.

Hey hey, I just released Cloud Castles: https://youtu.be/dLghAZpR9hk a melodic Drum&Bass track with quite some Linux support. Two tracks of Yoshimi, strings, trumpet, trombone and mellotron choir from LinuxSampler, drums, risers and special effects from Csound. The Csound elements were rendered to disk and then loaded into LinuxSampler using SFZ format. In processing TAP, CAPS and Fons' LADSPA plugins were used, as well as the Dragon Reverb LV2 plugin, loaded into mod-host. As ever MIDI sequencing and arrangement in Midish and all audio recording, mixing and processing in Nama.

[LAU] threadirqs suspected to cause xruns

by Moshe Werner

Hello everyone, so I ran into trouble with a new machine I built recently. It appears to be that when I enable threadirqs or use an rt-Kernel, I am getting an xrun inferno. At first everything is fine but after a few seconds/minutes of playback I get thousands of xruns. I am on Manjaro (KDE), the kernels I tried so far are 5.8.3-2 - working ok'ish without threadirqs enabled 5.6.19_rt12-3 - bad 5.4.59_rt36-1 - bad The funny thing is that I had a nice running system at first (around two months ago) on the same machine, the xruns started suddenly out of the blue. (Kernel update?) Configuration is Ryzen 5 3600 B450 Aorus pro Motu 1248 Manjaro KDE I tried to higher the buffers to 2048, didn't help. I installed an USB2 PCIe card so that I could separate the usb audio interface from other stuff and prefer its IRQ with rtirq. Nothing helped. What could be wrong? I would love to hear your opinions Best regards Moshe Werner
