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.

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? So, here I stand, I can do no other root(a)worik.org 021-1680650, (03) 4821804 Aotearoa (New Zealand)

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

mioctl: open-source iConnectivity mioXL/mioXM control software

by Panu Matilainen

Hi there, This is the initial announcement of mioctl project, bringing iConnectivity X-series (mioXL, mioXM) configuration to Linux and other platforms: https://codeberg.org/pmatilai/mioctl Whereas the the previous generation interfaces from iConnectivity was well-documented and for which an open-source GUI application already exists [1], the X-series control protocol is completely different and undocumented as of this writing, so this project is reverse-engineered by analyzing RTP traffic between Auracle and a mioXL. It is early days in the project but what it can do right now is - List, load and save (including rename) presets - List, add and remove routes - List device ports by their names - List active remaps and filters - List connected usb hosted devices - View device information (model, serial, firmware version) - View network configuration For many missing functionalities it's merely a matter of finding the time to to implement, USB host reservation looks more complicated but should get there eventually.

update of libzita-resampler

by Fons Adriaensen

Hello all, Release 1.8.0 of the zita-resampler library is now available at <http://kokkinizita.linuxaudio.org/linuxaudio/downloads> * Both the Resampler and VResampler classes can now be compiled to use SSE2 intrinsics. This at least doubles the speed, and is enabled in the supplied Makefile. * Some new documented test programs, also showing how to use the two classes. * Some (minor) bugfixes. This should be a drop-in replacement for 1.6.2, which will remain available for some time in case there are any problems. Enjoy, and best wishes for the next solar orbit ! -- FA

Greetings ! https://www.youtube.com/watch?v=blAUTXw9tiY An excerpt from a long moody guitar improvisation with a drone sequence in VCV Rack. Very simple throughout but maybe a peaceful listen, maybe a little reflective. I hope all LAU folk are enjoying a safe and mellow holiday season ! All blessings upon you all. :) Best regards, dp
