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] 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?

[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] 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] 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".
