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

[RFC] A “poor man’s”, yet professional level studio setup

by Francesco Napoleoni

Hi everyone Following my question about JACK and tempo transmission over a network, I felt the time is right for me to share some ideas about possible setup(s) of a studio mainly based on free software. The key idea is that such a studio is to be distributed among many hosts connected together with a fast local network. While the infrastructure should run primarily on FLOSS software, we should not shun proprietary tools, allowing a certain grade of interoperability between different systems (OS and applications). I don’t really know if I’m telling nonsense, but these ideas stem from my own experience over the years: the main use case for me is to make music for videos, being assisted in score and parts preparation, as well as “quick” mockup creation. Since money has always been tight for me, but I am a musician with enough curiosity and a certain experience with computers, I have been fiddling with Linux and music software for many years. What I’m trying to demonstrate is that the effort of integrating FLOSS and proprietary s/w with the great possibilities of modern and inexpensive h/w could give a professional great flexibility and relative ease of use, while keeping “low” costs and minimizing licensing and forced obsolescence woes. Basically, what I am trying to achieve is a network mainly made of Ethernet cables (while minimising audio cables), with the following nodes: * a master (or maybe better, a “conductor” ;-) ) machine controlling and transmitting the transport information, ideally a tablet or a minipc with a touchscreen showing the “big clock” and the “big buttons” (transport controls) * another machine (the router) with audio h/w and a DAW, receiving audio data from the network. The same machine could also host a notation software, perhaps * optionally, a machine showing a synced video * N >= 1 hosts running synths, virtual instruments, rocket launchers, microwave ovens getting the lunch done while I’m thinking of these things... ;-) On the FLOSS side, I think there are many of the right tools to implement my idea, I’m using them since many years. Here’s a incomplete list of them: 1) JACK (obviously ;-) ) 2) Cadence/Claudia 3) Carla 4) Qjackctl (gives me the “big clock” and the “big buttons”) 5) Ardour 6) MuseScore 7) Xjadeo While all of these tools do a great job (*really* great), there is still a big plumbing and tuning work to do. Actually this is the hardest part. ##### Personally, being a classical trained musician, I tend to compose using a notation software, with close attention to score neatness: I still prefer my music being played by humans rather than virtual gizmos. But I’m a “poor man”, so my great score is also to be “hashed” into a MIDI file, whose tracks are to be assigned to virtual (grrrr...) instruments, which in turn are to be mixed together, and the whole composition synced to a video. Since I cannot afford buying an expensive Mac nor can I pay for a plethora of licensed software, the challenge is to achieve similar results with alternative means. With this post I hope to start a constructive discussion about the potential of FLOSS music software and practical uses of it, instead of or in conjunction with other kinds of software, in professional environment. ciao Francesco Napoleoni

ssr and alternatives

by Brandon Hale

Hey everyone, Have you ever had any luck with soundscape renderer (ssr)? I have been having issues opening audio files with it, and am working with the developers on github right now to see what fixes that may be possible. Are there any good alternatives for rendering ambisonic and wavefield synthesis audio files? Thank you for any help you may be able to offer, Brandon Hale

[music] Rebecca auf dem Trekka

by Jeanette C.

Hey hey, I'd like to share my latest song: https://youtu.be/hc4brgfSGzg Direct OGG download: https://www.dropbox.com/s/lmwx4bkp39wye6h/rebecca_auf_dem_trekka.ogg A bit of electro fun, don't mind the German lyrics (or samples). This song features my friend Beccy "Rebecca auf dem Trekka" Schaefer, as well as F.W. Yilmaz. >From the Linux side as well as the usual Midish sequencer and Nama for the whole production, this song uses Csound for the vocoder sound, using my VC-110 vocoder UDO. The song is a bit of a pastiche of late 90s dance group Music Instructor, if anyone remembers them, with loats of monophonic goodness. Best wishes and have a nice Sunday, 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 You should never try to change me I can be nobody else And I like the way I am <3 (Britney Spears)

Help with jack-volume please

by drew Roberts

I am deep down a rabbit hole trying to help someone with something that I think should be simple. I may be about to solve it in a convoluted way. I need to be able to use jack-volume: https://github.com/voidseg/jack-volume to mute or unmute or raise or lower the volume on command (eventually from a script, probably python.) Has anyone ever used jack-volume before? Can anyone explain how it should work? Test to see if they can get it to work? Iiuc, it uses OSC to communicate from the (python) client to the jack-volume (server). I have never really used OSC either. Does the protocol contain acks that I can look for with wireshark? What else should I ask? all the best, drew -- Enjoy the *Paradise Island Cam* playing *Bahamian Or Nuttin* - https://www.paradiseislandcam.com/

[music] Arctic 80

by Jeanette C.

Hey hey, this is my latest song: https://youtu.be/ypm4h8gD0s4 and for OGG download: https://www.dropbox.com/s/4o9red2nzjl3rex/arctic_80.ogg The song was written as part of a challenge or competition by the DJs for Climate Action (https://djs4ca.com) to use their sample pack, which was created from sample of the Green Peace sound library. The sample pack contains pure field recordings and loops and oneshots made from these. The competition is still running till the end of February. Talking to a friend just before beginning the song, we talked about the genre of slaphouse, so I tried to encorporate something from slaphouse into this track. On the Linux side I used a lot of LinuxSampler, some Csound to create my riser - based on samples - and Yoshimi the the rhythmic main pad. Though the rhythm was created in my DAW, by automating the volume with an LFO. Enjoy, feedback would be welcome!

A huge thanks to those working on FLOSS

by Will Godfrey

This is just a shout out to acknowledge the fact that there are a lot people out there who, in spite of worries about home, family and jobs, in these especially difficult times, *still* manage to significantly advance the software we all rely on. As one of the 'Idle Poor' (retired), I don't lose sight of the fact that this is a considerable effort on their part, for which there are few thanks. -- Will J Godfrey http://www.musically.me.uk http://yoshimi.github.io Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.
