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

Release(?): A web based multi-track video player with volume mixer

by Laborejo Software Suite

Ladies and Gentlemen, this is some form of release. Example first: https://laborejo.org/multichannelplayer/ Have you ever tried to convince your friends and family to install a Linux system just so they can replicate your modular setup to listen to a pre-production where they are supposed to play the saxophone solo? Me neither. But I don't think it would work. Instead: This web software with the catchy name Multichannel_Web_Video_Audio_Player_With_Volume_Mixer is a tool for the boss (you) of ensembles and bands to distribute pre-productions for practice. But nothing keeps you from using it for real music with, as some kind of novelty player. The user can adjust the volume levels of individual instruments and follow along a visual presentation (notation, conductor video etc.). This includes optional tracks, such as metronome clicks, spoken instructions or alternative versions of tracks. Because it relies on simple video files there is no limit to quality and flexibility. Works in every browser. No downloads. No obscure technology is involved. This can be used by the 60+ generation in your choir. The provided Git/README (see link below) gives more ideas and examples why this tool could be beneficial to you. The README also helps to setup your own player and offers a workflow to produce videos, which is quite complicated to be honest. This is not a "proper" release because there is nothing to package. You just copy files to your web server. License is AGPL 3 or later. https://git.laborejo.org/lss/Multichannel_Web_Video_Audio_Player_With_Volum… Yours, Nils Laborejo Software Suite https://www.laborejo.org

can jackd or ardour be forced to use interleaved mode?

by Chris Caudle

Does anyone know if jackd (or the Ardour ALSA backend) can be forced to use interleaved mode? I am trying to work around a problem where a driver only supports interleaved access, but apparently jackd and Ardour try to open in non-interleaved mode. In parallel I am helping someone else check if there is some function missing that should inform applications that only interleaved mode is supported, and someone else is going to look at adding non-interleaved mode, but in the mean time I would like to find a work around if possible. -- Chris Caudle

Minimalist telephone interview setup

by Alf Haakon Pietruszka Lund

Dear list! I just spent a lot of time finding a good setup for telephone interviews. In case someone else is interested for making podcasts or live shows of some sorts, I thought I'd share the setup: # Hardware Laptop, smartphone, USB interface, iRig 2, microphone, headphones. XLR cable for the mic, 2 Jack - Jack 1/4" TS cables, USB cable. I'm switching between an Edirol UA-25ex and a Focusrite Scarlett 2i4. Proper connection of the phone to the setup was a headache and I spent quite some time testing a range of adapters. Most of them require an electret mic to function, which does not go well with my setup. Thanks to https://m.youtube.com/watch?v=wl6YuVu_v_g for pointing me to the iRig. # Connections Mic > USB 1 USB out 1 > iRig instrument input iRig amp out > USB 2 iRig < > telephone iRig set to FX To cancel echo from my own voice the Input / Monitor selector on the USB needs to be set almost fully counter-clockwise (almost input only). # Software Kubuntu Studio 20.04, Ardour 6.6, Studio Controls 2.1.64, Carla 2.3.0, Ubuntu studio backports PPA. # Software connections 1. Set Ardour to handle monitoring 2. Set Ardour Master to send L/R to System playback 2 3. Set up a mono foldback bus in Ardour for mix minus (everything except the caller). Foldback sends to System Playback 1 4. Use Carla > Patchbay to disconnect System playback from pulse_out Using a cheap Shure PG58 mic this setup is close to noiseless, even in my bedroom home office :-) Regards, Alf

List of FOSS Sampled Instrument Libraries for musicians - Hand selected and curated

by Laborejo Software Suite

Hello LAUs, Here is a list I am working on at the moment that I wanted to share with you. I feel like I've written this already in 2012, but some stuff is worth repeating :) https://hilbricht.net/foss-sampled-instruments.html "This is a hand selected and curated list of sampled music instrument libraries for software samplers that musicians can use without worrying, but which are also free and open source. Through strict requirements and thorough research we hope that this list can be trusted." (Guest appearances by Aeolus and setBFree :)) It is work in progress, but already useful, I hope. Yours, Nils

Re: [LAU] List of FOSS Sampled Instrument Libraries for musicians - Hand selected and curated

by Laborejo Software Suite

Hi Paul. thanks for the answer. The following is not meant as "told you so!". But I also want to show, that I care about this subject and made my homework. > sorry, that reply may have sounded a bit grumpy. it's just a bit irritating > sometimes to see well-intentioned efforts that seem to miss so many of the > resources they need to cover in order to give people a full picture. And sometimes a well meaning reply is also wrong: That Aeolus and setBfree are sample-less software synthesizers was not only hinted at through " Guest appearances by Aeolus and setBFree :) " but it also mentioned three times on the website itself. Once under "All software synthesizers" and then in each individual description. The samples from pianobook.co.uk all do not fulfill my requirements. See also their terms and conditions: https://www.pianobook.co.uk/terms-conditions/ Quote: " You may not sell sample(s), or give away any sample(s) for use by any other person(s)." And to anticipate one possible reply: My list is not a matter of what is fair and moral and possibly enough to make music. It has a 100% clear, law to the letter, no exceptions approach. I also wrote: "The strict constraints mean that this list will never be very large. Creating sampled instruments is a time-consuming and expensive task and is usually undertaken with the intention of making money from the result, thus not distributing the instrument as free and open source. This is by no means condemnable, but in this case it is simply not our topic. " And finally, from your .sf2 image I can tell at a first glance several well-known illegal rips, instances where the authors falsely claimed "public domain" and cases where the license simply do not meet my requirements, the requirements I prominently put in their own chapter. For example Florestan is well know copyright infringement, SC55 is already clear that these are just Roland samples, G-Town is not as free as people like to think, they are probably worth an entry on my "Other list" (that is linked on the page). Some of the .sf2 are synthesizer sounds, which I clearly declared "out of scope", even if they were CC0 sf2. And maybe they are just bad sounds. As I wrote: "They either have to be of decent quality, or at least be the only ones of their kind." For example balafon1.sf2, which I even created an .sfz version from in 2012. However, I would not recommend that to anyone because I dislike the sound. So, it is possible that a few of these .sf2 are indeed good fits for my list. And in this case I welcome any suggestion, as written on the page. However, I require a source that I can review. With the risk to sound grumpy as well: This time my efforts were already ahead. The "full picture" is sadly not as full as it should be. Not many people have the time, money and skills to produce samples, and that shows. People are desperate and want every sample-lib to be free and good. But most of the time they aren't, but yet another EMU Proteus rip, or something like this. I hope this example of the research-and-elimination process shows why I think I am the right person to create that list.

Transient Detection

by Brandon Hale

Hello all, I am looking for a program that can chop an audio file by its transients. Are there any good tools for doing that? I really would like a command line program ideally, as I want to split up a whole folder of drum breaks into individual transients. Thanks so much for any help you can offer, Brandon Hale
