Hi all! I'm looking for a way to run sfz files on a raspberry pi 4. I need to run several sfz files simultaneously (on different midi channels, one midi input and rudimentary mixing is sufficient. The pi has a fresh debian bookworm install... What are my options? Thanks in advance! -- Atte http://a773.dk/latestyoutube

using nvidia hdmi output with jack (through zita or alsa_out)

by Athanasios Silis

Hi all, I use jack as client (so with -dnet backend) and I'd like to route some streams to the hdmi output which is connected to a AV amplifier. $ aplay --list-devices | grep -vi subdev **** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC1150 Analog [ALC1150 Analog] card 0: PCH [HDA Intel PCH], device 1: ALC1150 Digital [ALC1150 Digital] card 1: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0] card 1: NVidia [HDA NVidia], device 7: HDMI 1 [HDMI 1] card 1: NVidia [HDA NVidia], device 8: HDMI 2 [HDMI 2] card 1: NVidia [HDA NVidia], device 9: HDMI 3 [HDMI 3] card 1: NVidia [HDA NVidia], device 10: HDMI 4 [HDMI 4] card 1: NVidia [HDA NVidia], device 11: HDMI 5 [HDMI 5] card 1: NVidia [HDA NVidia], device 12: HDMI 6 [HDMI 6] and $ aplay -L | grep -vE '^ ' default surround21 surround40 surround41 surround50 surround51 surround71 null samplerate speexrate jack oss pulse upmix vdownmix [...skipped all PCH entries...] hdmi:CARD=NVidia,DEV=0 hdmi:CARD=NVidia,DEV=1 hdmi:CARD=NVidia,DEV=2 [...] dsnoop:CARD=NVidia,DEV=3 dsnoop:CARD=NVidia,DEV=7 [...] hw:CARD=NVidia,DEV=3 hw:CARD=NVidia,DEV=7 [...] plughw:CARD=NVidia,DEV=3 plughw:CARD=NVidia,DEV=7 [...] usbstream:CARD=NVidia attempting to start zita-j2a or alsa_out starts up fine but I get no sound afterwards: *$ zita-j2a -j nv_out -c 8 -n2 -p1024 -r 48000 -d hdmi:NVidia,0* I have also tried other devices hdmi:NVidia,x # where x = 0-6 hw:NVidia,y # where y = 3,7,8,9,10,11,12 I also tried desperately some dmix and plughw devices. none produces any sound. Please note that if I don't use jackd, but instead output sound to pulseaudio (where hdmi output is selected as default), sound works fine. Googling about it only helped confuse me further because i am now not even sure if simple PCM output (which is what -I presume- zita outputs) is the "right type of stream". i.e. does pulseaudio convert the stream to some digital DTS/AC3 etc format instead of pcm ? Thank you in advance for your help

Re: jackd suddenly stopped working

by Athanasios Silis

you were absolutely right. I did not know pipewire-jack lacked the backends. So it appears that the latest auto-update reverted my settings - during my initial installation of ubuntu studio 24.04 I had switched from pipewire-jack to jackd+pulseaudio (using "ubuntustudio audio controls") . anyway it is indeed fixed. I wonder if there was any way that I could "see" that the pipewire-jack was selected other than the fact that the backends were missing. Thanks again for the reminder that helps me solve this.

jackd suddenly stopped working

by Athanasios Silis

Hi all, I am using ubuntu studio 24.04 and it looks like jackd2 has stopped working on a jackd client that I am using: I used to start normally the jackd session as $ jackd -dnet -C 4 -P 8 but I've been seeing these messages since last night: jackdmp 1.9.21 [...] [W][02502.216661] default | [ control.c: 67 jackctl_server_create2()] not implemented 0x573493a90ec0 0x573493a91020 0x573493a910f0 [W][02502.216855] default | [ control.c: 154 jackctl_server_get_parameters()] 0x57349bb68d10: not implemented [W][02502.216925] default | [ control.c: 142 jackctl_server_get_drivers_list()] 0x57349bb68d10: not implemented [W][02502.216966] default | [ control.c: 225 jackctl_driver_get_name()] 0x57349bb68cf0: not implemented *Unknown driver "net"* [W][02502.217019] default | [ control.c: 94 jackctl_server_destroy()] 0x57349bb68d10: not implemented I am mostly worried about this "unknown driver net" messages, but perhaps the warnings are also relevant. Indeed something is changed and the backends have vanished: $ jackd --help [...] Available backends: [W][03817.946848] default | [ control.c: 233 jackctl_driver_get_type()] 0x5a35d9340cf0: not implemented [W][03817.946852] default | [ control.c: 225 jackctl_driver_get_name()] 0x5a35d9340cf0: not implemented dummy (slave) [W][03817.946857] default | [ control.c: 165 jackctl_server_get_internals_list()] 0x5a35d9340d10: not implemented Available internals: [W][03817.946863] default | [ control.c: 94 jackctl_server_destroy()] 0x5a35d9340d10: not implemented I found this topic https://linuxmusicians.com/viewtopic.php?t=19590 where reinstalling jack in arch fixed their issue.. I tried the same as $ dpkg -l | grep jackd $ sudo apt install --reinstall jackd jackd2 jackd2-firewire libjack-jackd2-0 libjack-jackd2-dev but the issue persists. I assume some automatic update caused this but I wonder if anyone else has seen this and if you managed to fix it somehow. Thank you in advance for your help

Ratatouille.lv2 v0.9.6 released

by Hermann Meyer

Ratatouille is a Neural Model loader and mixer for Linux/Windows. This release implement a little ramp on Model file switching to avoid pops or clicks. Also provide binaries for older CPU's on windows. Ratatouille allow to load up to two neural model files and mix there output. Those models could be *.nam files <https://tonehunt.org/all> or *.json or .aidax files <https://cloud.aida-x.cc/all>. So you could blend from clean to crunch for example, or, go wild and mix different amp models, or mix a amp with a pedal simulation. Ratatouille using parallel processing to process the second neural model and the second IR-File to reduce the dsp load. The "Delay" control could add a small delay to the second model to overcome phasing issues, or to add some color/reverb to the sound. To round up the sound it allow to load up to two Impulse Response files and mix there output as well. You could try the wildest combinations, or, be conservative and load just your single preferred IR-File. Each neural model may have a different expected Sample Rate, Ratatouille will resample the buffer to match that. Impulse Response Files will be resampled on the fly to match the session Sample Rate.

Release aloop v0.3

by Hermann Meyer

aloop is a audio file looper for Linux using PortAudio as backend (jack, pulse, alsa), libsndfile to load sound files and zita-resampler to resample the files when needed. The GUI is created with libxputty. aloop comes with the following features: * support all file formats supported by libsndfile. * resample files on load to match session Sample Rate * file loading by drag n' drop * included file browser * open file directly in a desktop file browser * open file on command-line * create, sort, save and load playlists * select to loop over a single file or over the play list * move play-head to mouse position in wave view * set loop points for start/end loop * save loop points in play list * save selected loop as wav file * play backwards * volume control * endless looping * break playback (keyboard support space bar) * reset play-head to start position (keyboard support courser left) This release add support for drag and drop indicator inside the playlist. It may as well fix some small bugs, or, maybe introduce new ones. Dependencies * libsndfile1-dev * portaudio19-dev * libcairo2-dev * libx11-dev Project Page: https://github.com/brummer10/aloop Release Page: https://github.com/brummer10/aloop/releases/tag/v0.3

ImpulseLoader.lv2 v0.4 released

by Hermann Meyer

ImpulseLoader is a simple, mono, IR-File loader/convolution LV2 plug for Linux and windows. This release fix issues with arbitrary buffer sizes. IR-Files could be loaded via the integrated File Browser, or, when supported by the host, via drag and drop. A pop up menu provide quick access to all IR Files in the current loaded Path. If the IR-File have more then 1 channel, only the first channel will be used. IR-Files will be resampled on the fly to match the session Sample Rate.
