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.

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?

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

A Bandcamp Album

by Will Godfrey

First off, this is not my link but from the Sound On Sound website. However I think it's appropriate as all the tracks are offered free of charge, but if you do buy, all the proceeds go to the Nordoff Robbins Music Therapy Charity As the only Linux representative, I have one track on there. https://sosforumalbum.bandcamp.com/album/the-3rd-sos-forum-album?from=fanpu… -- Will J Godfrey https://willgodfrey.bandcamp.com/ http://yoshimi.github.io Say you have a poem and I have a tune.

Pulseaudio not starting correctly

by Kevin Zembower

Hello, all, I'm having problems with pulseaudio on my Ubuntu 18.04 system, and I think I've narrowed it down to pulseaudio not starting correctly on system reboots. After I reboot my system, I have no input or output devices shown in the sound control panel, and can't hear anything. I can see pulseaudio running, however: $ ps aux | grep pulse gdm 1832 0.0 0.0 1121148 16396 ? Ssl 14:31 0:00 /usr/bin/pulseaudio --daemonize=no $ I can't kill it: $ pulseaudio --kill E: [pulseaudio] main.c: Failed to kill daemon: No such process $ ps aux | grep pulse gdm 1832 0.0 0.0 1121148 16396 ? Ssl 14:31 0:00 /usr/bin/pulseaudio --daemonize=no $ sudo pulseaudio --kill E: [pulseaudio] core-util.c: Home directory not accessible: Permission denied E: [pulseaudio] main.c: Failed to kill daemon: No such file or directory $ I get these messages in /var/log/syslog when I reboot: Sep 27 14:26:30 kevin-desktop org.gnome.Shell.desktop[2108]: ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused Sep 27 14:26:30 kevin-desktop org.gnome.Shell.desktop[2108]: ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused Sep 27 14:26:31 kevin-desktop systemd[1703]: pulseaudio.service: Main process exited, code=killed, status=9/KILL Sep 27 14:26:31 kevin-desktop systemd[1703]: pulseaudio.service: Failed with result 'signal'. Sep 27 14:26:32 kevin-desktop systemd[1703]: pulseaudio.service: Service hold-off time over, scheduling restart. Sep 27 14:26:32 kevin-desktop systemd[1703]: pulseaudio.service: Scheduled restart job, restart counter is at 1. Sep 27 14:26:32 kevin-desktop pulseaudio[4004]: W: [pulseaudio] pid.c: Stale PID file, overwriting. However, if I manually start it, I get two copies. I also get all my input and output devices back in the sound control panel. $ pulseaudio --start $ ps aux | grep pulse gdm 1832 0.0 0.0 1121148 16396 ? Ssl 14:31 0:00 /usr/bin/pulseaudio --daemonize=no kevin 3901 2.7 0.0 1457716 16752 ? S<l 15:30 0:00 pulseaudio --start $ And, sound works again, although with some oddities. I can hear the 'pock' when I adjust the volume with the sound control panel, but not with the volume control in the upper right of my desktop. And, the sound control panel Test Speakers don't work, they don't even change visually from 'Test' to 'Stop' like they used to. Any ideas on how to fix this? I've really thrashed the sound system on my workstation, trying to play MIDI sounds through Zoom and other tasks. I've added a lot of sound software, like Cadence, but then thought I removed it all because it wasn't working. I reinstalled pulse-base and alsa, but this didn't work. Thanks for any suggestions or advice. -Kevin

Problem with input/output of the RME Fireface 802 sound card in Ubuntu Studio 20.04 with Jack

by Sebastian Roth

Hello everyone, I am new to this list and also new to Linux. But need Linux to play a virtual acoustic scene for studies with hearing aid users. First, about my setup. I have an RME Fireface 802 sound card that should drive 12 speakers in a speaker circuit. I use Ubuntu Studio 20.04 LTS as operating system and realize the routing via JACK. The Fireface is connected to the computer via USB and runs in ClassCompliant mode, because RME does not provide drivers for Linux. According to RME the ClassCompliant mode should allow in- and output of all channels also with Linux. The soundcard is recognized and I can also use 8 output channels for playback. But I need all 12 output channels including the two headphone outputs. JACK recognizes 22 channels or shows them in the graphical user interface. But the outputs 1 and 2 of the Fireface do not provide playback and no input is recognized. Does anyone have experience with the Fireface 802 in Linux or had a similar problem with an RME soundcard and can help me? Thanks for any feedback! Best regards, Sebastian

[semi-OT] acoustic Instrument question

by Jeanette C.

Hey hey, I'm looking for the name to an instrument. I had a feeling I was looking for a whirly tube (or corrugaphone), but apparently not. I'm looking for the sound in this song: https://www.youtube.com/watch?v=m-jYpFa3Ppk audible between 22-27 seconds. It sounds like a whispering diggeridoo or jaw harp. I thought a corrugated tube could produce this sound when whilred, but all demos I heard of this were much higher and much more pronounced in clear pitch. I'd be very grateful if someone could give me a clue or pointer of how to continue the search at least.

[music] Real love

by Jeanette C.

Hey hey, my latest track "real love" is inspired by Simon Collins' solo debut (All of who you are" and is probably an indie/electro pop ballad: https://youtu.be/xkDbP3DHL_U Direct OGG download: https://www.dropbox.com/s/cv0ipr2o1f7fx5d/real_love.ogg It was said that this might be my best production yet, even with me spoiling the song by singing. :) On the Linux side I used LinuxSampler with several free and commercial libraries and the usual production and recording software. Special credit should go to the TAP chorus, which is beautiful! Lyrics follow below. Best wishes, Jeanette *** Lyrics for "Real love" *** [Verse] Many a time - far at sea - you are my lifeline With just the smile in your voice. When events bare me down until I'm supine, I feel your call and I have no choice But to shoulder the weight of the world like a cloud... Thus in fade I rejoice With my feet on the ground and my heart reaching out... - Patiently listening to the lonely, Solitude melts in your spell. With wide open arms you never knowingly Coax me like pearl from a shell. The turmoil you cause, you will sooth with a laugh Towards the storm... Then you summon the light and the blue black above is torn... [PreChorus] Hell is on fire Heaven's burning bright. 'Cause now I aspire To ask if you requite [Chorus] My love (all my love) To live outside a dream on safer ground In your love (all your love) To face our days And make our ways Hand in open hand... [Verse] Compassion alone shall bestow your noble birthright, And thus give credence to you. My princess, hold court with the timid and the forthright! Joy will provide all that is due. And together we serve with the creatures of earth Where we stay. And in kisses we share what a passion is worth Day to day. [Prechorus] [Chorus] [Instrumental] [Chorus] *** End of lyrics *** -- * 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 Don't, don't let me be the last to know Don't hold back, just let it go <3 (Britney Spears)

live with keyboard

by Gerhard Wolfstieg

Hello dear readers, I wish to find the best way to play live on a MIDI keyboard with softsynths and plugins in my linux notebook (avlinux or debian – or another if someone knows a better one for this purpose) with a good USB audio interface (komplete audio 6, which is running very well with jack1 (possibly changing to jack2)) Mostly I have to be able to switch between preconfigured sets of sounds quickest and easy. The topic is boundless. Therefore I ask you for some orientation. Grüße, Gerhard
