Hi all, Industrializer generates synthesized percussion sounds using physical modelling. The range of sounds possible include but is not limited to cymbal sounds, metallic noises, bubbly sounds, and chimes. After a sound is rendered, it can be played and then saved to a .WAV file. I think Power Station Industrializer v0.2.7 is matured enough to be released :-) It contained only few minor changes compared to the latest pre-release, but is tested well. You can download it here: https://sourceforge.net/projects/industrializer/files/ 0.2.7 release contains the following main new features (compared with v0.2.6): - Discretization rate selection for both playback and WAV export - Improved accuracy of setting some parameters - Rendering and playback can be interrupted. Playback can be retrigged at any time - Both actuation and sampling nodes are made selectable. This facility allows you to vary somehow the timbre of the sound and even create stereo samples with some phasing effects. Although Industrializes cannot directly deal with stereo samples, you can first render and save a sample, then change the sampling node without touching the other parameters and render another sample, after that use these samples as left and right stereo channels. Regards, Yury.

[LAU] short audio drop out when new jack clients are created and connected

by Peter P.

Hi, I am currently giving linux-show-player a try but the following problem might happen with other software as well. In linux-show-player audio files can be played back from a cue list. Each cue is implemented as a separate jack client. I am having the problem that starting a cue, while another one is already playing, is causing an audible drop out in the audio processing. When running the software under alsa, this does not seem to happen. I suspect that creating and connecting new jack clients causes this to happen. No xruns happen though. I can not reproduce this exactly, although it happens at about 30% of cue starts. Increasing jackd's buffer size does not help so far. How can I go about to debug this further? Thank you! Peter

[LAU] jackd2 resume from suspend hangs

by Peter P.

Dear list, having just switched from jackd1 to jackd2 I notice that jackd hangs when issuing a "systemctl suspend" and resuming from that suspend with a USB Edirol UA-25 card. I am including relevant error messages below. Thank you for any pointers! Peter I run from the shell as follows jackd -v -t2000 -dalsa -r44100 -p512 -n2 -Xseq -D -Chw:UA25 -Phw:UA25 -i2 -o2 and clients can connect and play through it fine. When I issue the suspend and resume, jackd has printed the following: status error: No such device ALSA: channel flush for playback failed (No such device) JackAudioDriver::ProcessAsync: read error, stopping... Jack: JackPosixThread::ThreadHandler : exit When I try to connect with a client (mplayer) to it, mplayer hangs and eventually exits posting Cannot read socket fd = 7 err = Success CheckRes error JackSocketClientChannel read fail Cannot open MPlayer [109458] 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 [JACK] cannot open server Failed to initialize audio driver 'jack' [...] Exiting...

[LAU] Problem with a Vestax VCI-100MKII controller

by Daniel Swärd

Hi all. I'm hoping you can shed some light on a problem I have with a DJ controller (Vestax VCI-100MKII) that's also a soundcard. My problem is that when I connect it, it keeps disconnecting. I've tested this on two laptops, both running Ubuntu 20.04. One a bit older and newer one that only has USB-C, so on the newer one I connect the controller via a USB hub. syslog on the older laptop: Nov 30 14:33:12 wintermute kernel: [ 936.225155] usb 3-2: new full- speed USB device number 14 using xhci_hcd Nov 30 14:33:12 wintermute kernel: [ 936.373108] usb 3-2: New USB device found, idVendor=1aa1, idProduct=0220, bcdDevice= 1.00 Nov 30 14:33:12 wintermute kernel: [ 936.373120] usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Nov 30 14:33:12 wintermute kernel: [ 936.373123] usb 3-2: Product: VCI-100MKII DJ-Controller Nov 30 14:33:12 wintermute kernel: [ 936.373125] usb 3-2: Manufacturer: Vestax Nov 30 14:33:12 wintermute kernel: [ 936.380745] usb 3-2: current rate 48000 is different from the runtime rate 44100 Nov 30 14:33:12 wintermute kernel: [ 936.382717] usb 3-2: current rate 48000 is different from the runtime rate 44100 Nov 30 14:33:12 wintermute kernel: [ 936.386780] usbhid 3-2:1.5: can't add hid device: -71 Nov 30 14:33:12 wintermute kernel: [ 936.386793] usbhid: probe of 3- 2:1.5 failed with error -71 Nov 30 14:33:12 wintermute kernel: [ 936.387200] usb 3-2: USB disconnect, device number 14 Nov 30 14:33:12 wintermute systemd-udevd[12281]: controlC2: /usr/lib/udev/rules.d/78-sound-card.rules:5 Failed to write ATTR{/sys/devices/pci0000:00/0000:00:14.0/usb3/3-2/3- 2:1.0/sound/card2/controlC2/../uevent}, ignoring: No such file or directory syslog on the newer laptop: Nov 30 15:45:00 ono-sendai kernel: [107245.521851] usb 3-8.3: new full- speed USB device number 91 using xhci_hcd Nov 30 15:45:00 ono-sendai kernel: [107245.704167] usb 3-8.3: New USB device found, idVendor=1aa1, idProduct=0220, bcdDevice= 1.00 Nov 30 15:45:00 ono-sendai kernel: [107245.704171] usb 3-8.3: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Nov 30 15:45:00 ono-sendai kernel: [107245.704172] usb 3-8.3: Product: VCI-100MKII DJ-Controller Nov 30 15:45:00 ono-sendai kernel: [107245.704174] usb 3-8.3: Manufacturer: Vestax Nov 30 15:45:00 ono-sendai kernel: [107245.722561] usb 3-8.3: 1:1: cannot set freq 44100 to ep 0x2 Nov 30 15:45:00 ono-sendai kernel: [107245.725923] usb 3-8.3: 2:1: cannot set freq 44100 to ep 0x82 Nov 30 15:45:00 ono-sendai kernel: [107245.732227] usbhid 3-8.3:1.5: can't add hid device: -32 Nov 30 15:45:00 ono-sendai kernel: [107245.732236] usbhid: probe of 3- 8.3:1.5 failed with error -32 Nov 30 15:45:00 ono-sendai mtp-probe: checking bus 3, device 91: "/sys/devices/pci0000:00/0000:00:14.0/usb3/3-8/3-8.3" Nov 30 15:45:00 ono-sendai mtp-probe: bus: 3, device: 91 was not an MTP device Nov 30 15:45:01 ono-sendai kernel: [107245.890782] usb 3-8.3: USB disconnect, device number 91 Nov 30 15:45:01 ono-sendai systemd-udevd[127098]: controlC7: /usr/lib/udev/rules.d/78-sound-card.rules:5 Failed to write ATTR{/sys/devices/pci0000:00/0000:00:14.0/usb3/3-8/3-8.3/3- 8.3:1.0/sound/card7/controlC7/../uevent}, ignoring: No such file or directory Nov 30 15:45:01 ono-sendai systemd-udevd[127098]: controlC7: Process '/usr/sbin/alsactl -E HOME=/run/alsa -E XDG_RUNTIME_DIR=/run/alsa/runtime restore ' failed with exit code 99. >From this it seems that the common problem in the output is the "can't add hid device".
