Hi! I tried to make a Tascam US-122 "Classic" work with my Debian-testing-powered Thinkpad T410. I followed the instructions on https://alsa.opensrc.org/Tascam_US-122#Tascam_US-122_on_Debian_and_Ubuntu as far as I could (alsa-base is not in Debian, anymore) but once I tried to use the device for playback in pulseaudio I realized there was no sink created. Pulseaudio offers the possibility to use the TASCAM with "multiple input" besides "stereo input" (although I thought it's a stereo in/out device) but there was no option to use it as an output. I tried to use jackd to double-check the missing output, but it failed to startup. Reason: "cannot configure playback channel" The whole log (of the important part): "jackdmp comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK server starting in realtime mode with priority 10 self-connect-mode is "Don't restrict self connect requests" audio_reservation_init Acquire audio card Audio1 creating alsa driver ... hw:USX2Y|hw:USX2Y|256|3|44100|0|0|nomon|swmeter|soft-mode|32bit configuring for 44100Hz, period = 256 frames (5.8 ms), buffer = 3 periods ALSA: final selected sample format for capture: 24bit little-endian in 3bytes format ALSA: use 3 periods for capture ALSA: final selected sample format for playback: 24bit little-endian in 3bytes format ALSA: use 3 periods for playback ALSA: cannot set hardware parameters for playback ALSA: cannot configure playback channel Released audio card Audio1 audio_reservation_finish Cannot initialize driver JackServer::Open failed with -1 Failed to open server" Any ideas?

[Music] "Grüngürtel 7 pm" - pure Yamaha reface DX, produced with Ardour 6

by Christopher Arndt

Hi everyone, here's a little contemplative synthy tune I conceived - as the title hints at - on a sunny Monday evening in the park and recorded and mixed in Ardour 6 within the next few hours. https://soundcloud.com/spotlightkid/gruenguertel-7-pm All sounds are from a Yamaha reface DX FM synthesizer, so no FLOSS sound generators here and almost all effects are from the reface DX, but the track was done on Linux and with Ardour and additional effects (very few) are all Open Source. Download is enabled on SoundCloud for the track, if you want FLAC, and you can also download it here: * https://chrisarndt.de/music/homerecording/Gruenguertel%207%20pm.flac * https://chrisarndt.de/music/homerecording/Gruenguertel%207%20pm.ogg If you are interested in the synthesizer patches, let me know and I'll upload them somewhere (they are not compatible with any other Yamaha FM synth, though). Share & Enjoy, Chris

["Music"] Unquantized analogue chords

by Mario Lang

Hi. Definitely not a finished piece of music. Patched and tuned in basically just a few minutes, so there isn't any development or anything else you'd want to have from a track in this genre. And not even made with Linux as such. It is a all-hardware track, recorded with SuperCollider. However, we had a lot of fun performing it together. If you're still here, here goes the story: I have two Analogue Solutions Megacities. The megacity is an analogue step sequencer with 64 steps. It can be used in two-channel mode, so you get 2x32 steps. Since I have two of them, I patched them up to have 4 channels of CV output, directly going to a Döpfer A-111-4[1]. So I clocked the step sequencers with a slow pulse every 4 beats. And tuned some 7th chords by hand. Mind you, no quantisation in use. Since I was already sort of terrorizing my girl while preparing the patch, it turned out to be a wonderful opportunity to give her a hands-on dive into the world of modular synthesizers. She has a really good ear, and once I showed her which of the countless encoders were responsible for the individual chord tones, she was hooked and determined to make it sound passable. A minute later, she found herself twiddling the cutoff and resonance knobs on a x0xb0x as if that's what she always has been doing. So I couldn't resist and capture this magical moment of understanding. https://soundcloud.com/mario-lang/sunday-afternoon-acid-house [1] https://modular.blind.guru/Eurorack/Modules/A111-4.html -- CYa, ⡍⠁⠗⠊⠕

Recorded this a few days ago.

by Will Godfrey

This is an unedited improv where I was trying out a couple of my latest voice patches. I used two keyboards one set to transmit on MIDI channel 1 and the other on channel 2. The pads (LH) are 'Ghost Ensemble' and the lead (RH) is 'Angel Harp'. Some of the pauses are intentional others are "Heck! Where do I go now." :) http://www.kara-moon.com/forum/index.php?action=dlattach;topic=7471.0;attac… -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

Default (audio) devices in Plasma (KDE)

by Max

Hi list, since Kubuntu 20.04 there are big stars next to the volume controls for each audio device labelled "Default Device". First I thought that's cool, now I can set the default device and it stays that device. However, the system decides that if the user plugs in an USB soundcard the newly detected soundcard will be the new soundcard. :( In my case if I plug in a zoom H2_n recorder the desktop audio will be switched from the Jack Sink to the teeny speaker which is in that recorder. Not what is desirable. Is there a solution to this? https://imgur.com/LAzX8rg m

A linux-based FM radio station

by Ken Restivo

I'm happy to report that as of this morning, 100-Watt KNYO-FM in Fort Bragg California (http://en.wikipedia.org/wiki/KNYO-LP) is running on Linux, Linux Audio and Free Software. (Well, then again, I can't speak for their website; I didn't set that up, and it looks like an F5 box, dunno what they run. But the actual streaming and broadcast radio signal chain up to the transmitter is Linux.) The FM transmitter is in a remote location getting its audio program from a Raspberry Pi running Raspbian connected via DSL to a Linode running Airtime and Icecast2 for station automation and streaming. The studio machine is a Linux Mint XFCE box running The BUTT connected via DSL to the Linode and Airtime. I've done a few Liquidsoap customizations to Airtime to fill in missing features (AutoDJ, saving incoming streams, etc) and will be doing more, possibly contributing them upstream if I can keep them clean and general enough. -ken
