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.

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.

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?

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

[Music] The queen's fugue

by Jeanette C.

Hey hey, this is a three (or four?) part fugue, which I wrote for synthesizers: https://youtu.be/cIF0JocnaDA OGG version: https://www.dropbox.com/s/2kz8sb873rwsl3a/queens_fugue.ogg It is a proper expansion of the "fughetta" inside "The queen is dead": https://youtu.be/otTwVsenZ0I This time I did not use the samples supplied by Loopop for his "Mega contest", but my own hardware synthesizers. The main voice is the Waldorf Microwave Xt, a hommage to the Waldorf M (wavetable synthesizer) sound used in the original piece. The rest is all analogue, exploring both east and west coast synthesis. Again, there is a lot of automation inside the DAW to make the piece come alive. The fourth voice is introduced towards the second half of the piece and is actually a variation on the leading motif shifted somewhat in time. I think this is called closed voicing, though I may be mistaken. :) I hope you enjoy it, whichever techniques or instruments are involved. Best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c They say, break away - I'm missing out on the fun and games <3 (Britney Spears)

Current Developments in Linux Audio ?

by nik＠parkellipsen.de

Hi, I've basically been using the same configuration (Arch/ALSA/Jack2) for years now and it's stable and everything, but I feel like I've been living under a rock when it comes to Linux Audio developments, so I thought I'd reach out and ask if there's any current developments that I should follow or toy around with ... Best, Niklas

Pipewire, jack-midi, alsa-midi, rendering, freewheeling etc.

by Lorenzo Sutton

As there are interesting discussions about pipewire. I'll go with a somewhat open question. I'm wondering how will 'MIDI' work and especially if an how will alsa-midi applications be able to happily and collaboratively :-) work with jack-midi ones (currently provided by a2j), potentially with some improvement? Would it facilitate the vision, which I tried to discuss sometimes on this list, about being able to interconnect 'any' midi application on Linux _and_ facilitate the faster-than-real-time generation (rendering) of a digital file/stream of what the user 'hears'? :-) It seems that now pipewire does support freewheeling [1], and (maybe) that could be promising?

Someone hhtold me that I need to use virtual instruments for this instrument. Is it neccessary to install a daw in order to install the virtual instruments? Again I am new so anyone that can explain to me how to just Hear the instrument would be great.
