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

JACK and Sound OpenFirmware?

by Mario Lang

Hi. With kernel 5.7, my system finally switched over to snd_sof_pci for the intenal card. I can use mpv and alike via alsa directly, but when I try to start JACK I always get the following message: ALSA: cannot set period size to 1024 frames for playback Adding the verbose flag to JACK doesn't make it any more informativ regarding this problem. With the old hda driver, JACK was perfectly working with a buffer size of 1024 (and less). Does anyone know what I can do to make JACK work with the internal card? Or at least how to debug what is actually preventing it from working? I am using a Lenovo X1 Carbon 7th Gen. -- CYa

Need MIDI keyboard for Zoom Class

by Ivan K

I will be teaching a music course via Zoom this semester and have a large number of audio examples from web pages that I will be playing from the FireFox browser. In addition, I have a MIDI piano keyboard controller and a MIDI input on my M-Audio 2496 soundcard, and I would like to occasionally play at this keyboard for the class with a piano timbre. What are the easy options to set this up? I need to easily go back forth between playing audio from Firefox (which I assume uses PulseAudio) and the synthesizer that this MIDI keyboard will be triggering. Thank you, as always, for your replies.

spectmorph-0.5.1

by Stefan Westerfeld

spectmorph-0.5.2 has been released. The two new main features (synchronizing morphing with the song tempo and positional play) are explained here: https://youtu.be/6E4HClXdV_Y If you haven't watched our video tutorial for the instrument editor added in 0.5.0, you can do so here: https://youtu.be/JlugWYPDp84 Overview of Changes in spectmorph-0.5.2: ---------------------------------------- * Support bpm/beat synchronization for LFO - new presets using beat sync LFO: Mars / Saturn * Add WavSource custom position playback mode * New Instruments: Sven Ah / Ih / Oh (another male human voice) * Store data in XDG directories on Linux: - move ~/.spectmorph directory to $XDG_DATA_HOME/spectmorph - move ~/SpectMorph directory to $XDG_DOCUMENTS_DIR/SpectMorph - create $XDG_DOCUMENTS_DIR/SpectMorph directory when needed (on write) - backward compatibility: use ~/SpectMorph if it already exists * Bump number of control inputs from 2 to 4 * Implemented midi CC control for smjack (General Purpose Controller 1..4) * Fix crashes caused by dangling MorphOperator pointers * Fix loading floating point wav files * Minor fixes and cleanups What is SpectMorph? ------------------- SpectMorph is a free software project which allows to analyze samples of musical instruments, and to combine them (morphing). It can be used to construct hybrid sounds, for instance a sound between a trumpet and a flute; or smooth transitions, for instance a sound that starts as a trumpet and then gradually changes to a flute. SpectMorph ships with many ready-to-use instruments which can be combined using morphing. SpectMorph is implemented in C++ and licensed under the GNU LGPL version 3 Integrating SpectMorph into your Work ------------------------------------- SpectMorph is currently available for Linux, Windows and macOS users. Here is a quick overview of how you can make music using SpectMorph. - VST Plugin, especially for proprietary solutions that don't support LV2. (Available on Linux and 64-bit Windows/macOS) - LV2 Plugin, for any sequencer that supports it. - JACK Client. Links: ------ Website: http://www.spectmorph.org Download: http://www.spectmorph.org/downloads There are many audio demos on the website, which demonstrate morphing between instruments. -- Stefan Westerfeld, http://space.twc.de/~stefan

Noise generation plugin recommendations?

by Nikhil Nair

Hi, I'm looking for Ecasound-compatible plugins (e.g. LADSPA or non-GUI LV2) that do various types of noise generation. I've found ones which generate white or pink noise, but I'd like something that goes beyond that: e.g. S&H (Sample & Hold) noise with variable parameters, or even other noise-like sound effects such as rattling sounds and the like. Could anyone give me any recommendations, or point me in the right direction? I'm very new to the Linux audio plugins world, so I'm probably missing an obvious approach re how to go about looking for such things. Thanks, and best wishes, Nikhil.

[LAA] Mamba - Virtual Midi keyboard for Jack Audio Connection Kit release 1.5

by Hermann Meyer

Hi Mamba release v1.5 is out Mamba is a Virtual MIDI keyboard with some extended, unique features. So it could load/play and save MIDI files, it visualize the played files on the keyboard, were it use a unique color for each channel. you could visualize a single channel, or all together at once. It could record your playing and play it back as endless loop. You could record a loop for each channel while the other channels still play. Note, that the loops don't be synced. So this is not for composing classic music, but to create Psychedelic Trance floors. Truly you could save your work as MIDI file and rework it in the DAW of your choice. It will record as well all incoming MIDI messages, so you could use it as well to record your external MIDI controller. // <https://de.wikipedia.org/wiki/Psytrance#Psychedelic_Trance_und_Psychedelic_…> Mamba also includes support by fluidsynth, you could load a soundfont and directly play along. It include controls for the fluidsynth reverb and chorus, and a selector to select a instrument/patch for each channel. Mamba will keep it's settings, so once a soundfont is loaded, on the next start you could just play along with the keyboard. You could load a new soundfont at any time. To use it as a plain MIDI keyboard again, you just need to exit fluidsynth via the menu and connect Mamba with the synth of your choice. Mamba is released under the BSD Zero Clause License license The GUI is build on libxputty - A damn tiny abstraction Layer to create X11 window/widgets with cairo surfaces https://github.com/brummer10/libxputty To build Mamba from source, the following dependencies must be meat. * libfluidsynth-dev * libc6-dev * libsmf-dev * libcairo2-dev * libx11-dev * liblo-dev * libsigc++-2.0-dev * libjack-(jackd2)-dev So, here is the project page: https://github.com/brummer10/Mamba and here you'll find the last release: https://github.com/brummer10/Mamba/releases/tag/v1.5 regards hermann
