Does anyone know of software that can generate MIDI messages from a touchpad? The idea would be to send CCs to a sequencer or soft synth, but being able to send it to an external hardware device would also be very useful. -- Will J Godfrey https://willgodfrey.bandcamp.com/ http://yoshimi.github.io Say you have a poem and I have a tune.

[LAU] jackd2 hanging after resume?

by Peter P.

Hi, Running jackd2 on an Edirol UA-25 USB interface as jackd -t2000 -dalsa -r44100 -p512 -n2 -Xseq -D -Chw:UA25 -Phw:UA25 -i2 -o2 I can not get clients to connect after having resumed the computer from "systemctl suspend". Upon resuming, jackd reports status error: No such device ALSA: channel flush for playback failed (No such device) JackAudioDriver::ProcessAsync: read error, stopping... and hangs. Trying to use mpv or puredata with this locked server then throw the same messages: Cannot read socket fd = 13 err = Success CheckRes error JackSocketClientChannel read fail Cannot open mpv client JackShmReadWritePtr1::~JackShmReadWritePtr1 - Init not done for -1, skipping unlock JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock Nevertheless, qjackctl indicates a running server but throws Cannot create new client JackPosixProcessSync::LockedTimedWait error usec = 5000000 err = Connection timed out Driver is not running Cannot create new client journalctl/dmesg show that the USB sound card is discovered as a new device after resuming from the suspend state. Stopping the server takes some time then, throwing: ALSA: channel flush for playback failed (No such device) Cannot stop driver port deleted: UA-25:midi/playback_1 port deleted: UA-25:midi/capture_1 Released audio card Audio2 audio_reservation_finish 11:05:51.251 JACK was stopped This problem does not exist when using jackd1. The computers internal soundcard (intel-hda) survives resuming from suspend with jackd2. What can I try next? Thanks! Peter

[LAU] Oscilloscope Suggestions

by Sirjohndfox

Greetings All, I just came into possession of a Behringer Arp 2600 clone. I would like some eye candy while I fiddle my way through learning synthesis. Can anybody suggest some oscilloscope software? I've tried a few things already but I'm interested in other's favourite solutions. Cheers John Sent with Proton Mail secure email.

[LAU] Can't seem to change index of audio controller

by Jeremy Jongepier

Hello, Got a new notebook with the following audio device amongst others: 64:00.5 Multimedia controller: Advanced Micro Devices, Inc. [AMD] ACP/ACP3X/ACP6x Audio Coprocessor (rev 63) ... card 1: acp63 [acp63], device 0: DMIC capture dmic-hifi-0 [] It is using, I think, the snd-soc-ps-mach kernel module but it seems this module does not respect the index option. I'd like to give this device a higher index so it doesn't get index 0. If I use something like the following configuration in /etc/modprobe.d/ it doesn't get picked up: options snd-soc-ps-mach index=12 Anybody any idea? And yeah, I know index is not a valid option for this module but the ALSA documentation states that all top level snd modules should respect this option. Or is this Pink Sardine stuff a whole different animal? And for the snd-hda-intel kernel module, is it possible to discern between devices when assigning indexes? As in, the snd-usb-audio module for instance has vid and pid options to discern between different USB audio and MIDI devices based on their vendor and product ID's. This is really handy as it allows you to assign fixed index numbers to these devices. The model and id options are not suited for this, they only allow you to actually set the model and/or id. Could very well this is not possible at all but I just want to be sure. Talking about USB, going lower than 64 frames/period floods dmesg with the following messages: [ 1223.745771] retire_capture_urb: 2362 callbacks suppressed [ 1223.759483] xhci_hcd 0000:66:00.4: WARN Event TRB for slot 1 ep 5 with no TDs queued? Is there anything I could do about that or is this the very limit this system can handle? No problem anyway since I barely run lower than 128 frames/period normally and even at 64 this system is pretty stable with bigger projects. But I just like to know how low this notebook can go. It's an AMD Ryzen 7 system so USB controllers are from AMD (USB ID's are 1d6b:0002/0003) Thanks in advance! Jeremy

[LAU] What software do I need to produce podcasts?

by Kevin Zembower

Hello, all, I've signed up for an Introduction to Audio Production course at my local community college. I mainly want to learn how to record audio in the field, and edit it into something like radio news segments or podcasts (for those too young to have heard of 'radio'). When I was playing around with this 5-10 years ago, the go-to software was Audacity, which I used and liked a lot. However, I understand that Audacity has gone through some upheavals. I'm on a Ubuntu 22.04 desktop, and I experimented at one time with PipeWire, but I can't remember what audio tools are on my system currently. Do I need a Digital Autio Workstation (DAW)? Which one, in the FOSS world, would you recommend? What audio tools (jack? pipewire?) do I also need? I'm sure that the college will have professional tools, in a lab, for us to use, but I'd like to see if I can duplicate all the assignments using FOSS tools. Thanks for any advice or guidance for me. -Kevin

[LAU] [ANN] Qtractor 0.9.39 - A Winter'24 Release batch #3

by Rui Nuno Capela

Hi there, twice again! Now making up the QStuff* third batch of the New Year... Qtractor 0.9.39 (winter'24) is out! Maybe, just maybe--no promises here whatsoever--this could be very well be the last before _the unthinkable_ 🐱? Change-log: - Added build checks on whether to use old or newer style of LV2 include headers. - Introducing new Transport/Step/Backward and Forward menu actions, to move the play-head backward and forward, in bar/beat/fraction (snap-per-beat) steps, respectively. - Introducing View/Options.../Display/Custom/Style sheet (*.qss) application themeing option. - Improved MIDI clip editor centering to current mouse pointer position in main timeline (tracks-view); on both horizontal and vertical axes. - LV2 Plug-in Control Input Port-change request extension feature support added. - Fixed an old one-off plug-in parameter change command aliasing (undo/redo). - Updated copyright headers into the New Year (2024). 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] Unable to start jack in real-time mode

by Arve Barsnes

Hello, I'm "suddenly" (after a couple months of disuse) unable to start jack in real-time mode, making ardour unable to take advantage of it. I've had more or less the same setup for more than 10 years, so I've really forgotten if there is anything else than the below that I could investigate. Tue Jan 23 20:21:51 2024: Starting jack server... Tue Jan 23 20:21:51 2024: JACK server starting in realtime mode with priority 10 Tue Jan 23 20:21:51 2024: self-connect-mode is "Don't restrict self connect requests" Tue Jan 23 20:21:51 2024: Acquired audio card Audio2 Tue Jan 23 20:21:51 2024: creating alsa driver ... hw:MobilePre|hw:MobilePre|128|3|48000|0|0|nomon|swmeter|-|32bit Tue Jan 23 20:21:51 2024: configuring for 48000Hz, period = 128 frames (2.7 ms), buffer = 3 periods Tue Jan 23 20:21:51 2024: ALSA: final selected sample format for capture: 16bit little-endian Tue Jan 23 20:21:51 2024: ALSA: use 3 periods for capture Tue Jan 23 20:21:51 2024: ALSA: final selected sample format for playback: 16bit little-endian Tue Jan 23 20:21:51 2024: ALSA: use 3 periods for playback Tue Jan 23 20:21:51 2024: ERROR: Cannot use real-time scheduling (RR/10) (1: Operation not permitted) Tue Jan 23 20:21:51 2024: ERROR: AcquireSelfRealTime error # ls -l /dev/rtc0 crw-rw---- 1 root audio 253, 0 Jan 10 20:00 /dev/rtc0 # grep audio /etc/security/limits.conf @audio - rtprio 99 @audio - memlock unlimited My user is a member of the audio group. This is a pure ALSA system, so there is no pulseaudio that could be the culprit. pipewire is installed, but have not been running at any time, although there might be something there? As far as I've figured, when it last worked I was on a 6.4.x kernel, I've been through a 6.5.x and have now had this problem on a few different 6.6.x kernels. From what I can gather, I've not changed anything that I can see. All help welcome. Regards, Arve

[LAU] jack_lsp for jackd1?

by Peter P.

It seems that the jack_lsp tool, which lists jack ports/connections on the command line, is only available as part of the jackd2 package on Debian. Is this intentional? For Debian oldstable it exists as part of the jackd1 package... thanks for any help! P
