[LAU] 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.

[linux-audio-user] Sub-harmonic generator? (LADSPA or VST)

by Tim Howard

Hello, Does anyone know of a good plugin that will generate subharmonics? I would like to put a little more low frequency "oomph" into my bass track. Preferrable LADSPA, but VST would work, too. Thanks for any help! -TimH

[LAU] Alternative FluidSynth GUI?

by Dan Capp

Research tells me that QSynth seems to be the only currently available/usable GUI for FluidSynth, but I get big xruns whenever I try and use it. FluidSynth itself doesn't cause me problems (I know because I'm able to use the FluidSynth-DSSI plugin fine in Rosegarden etc). The problem is that I want to use FluidSynth with Ardour3, but Ardour3 doesn't support DSSI plugins yet. So the only solution I have is to find a standalone interface for FluidSynth and then to link up using Jack. I looked at the old GUI 'FluidGUI' but it seems to be so old that it won't properly install on recent versions of Ubuntu. So does anyone know of: 1) A GUI for FluidSynth other than QSynth and FluidGUI?... or 2) An application other than the above 2 which would allow me to load soundfonts? Thanks in advance. - Dan

[LAU] Sound Devices USBPre2, UAC2 status

by shal＠free.fr

Hi, Some old posts exist about the UAC2 support for the Sound Devices USBPre2 but some problem remains. The current status is that this sound card is supported as a USB 1.1 card in high-speed mode. But this card is not seen as a Usb Audio Class 2 on Linux. On Mac OS X this card is recognized as UAC2. My principal problem is that the "device descriptor" provided by the card is always a USB1.1 class There is two modes of boot for the card (pressing the "1" button, the card is in full speed mode, without pressing in UAC2 mode) There is only one difference between these two modes in the lsusb -v : the "bInterval" go to 4 from 1. This is already view by Clemens on: http://lists.linuxaudio.org/pipermail/linux-audio-user/2011-October/081275.… In this another post, we can seen: Bernardo Barros wrote: > Ok, I reconnected without pressing "1". > > Bus 002 Device 002: ID 0926:0202 > Device Descriptor: > bNumConfigurations 2 Strange, I have never 2 on bNumConfigurations ! Somebody can test it on its card ? This is perhaps my problem, my card only provides one "Configuration Descriptor". The second one is certainly the UAC2 "Configuration Descriptor". The lsusb without 1 pressed : http://pastebin.com/8yjjASv7 The lsusb with 1 pressed : http://pastebin.com/pGFdjR4K The usbmon trace of the insertion of the usbpre2 (without "1") : http://pastebin.com/pySC4Age This sound card is great, it is very disappointing to not be able to used it with all functionnalities. I search help in order to debug this problem. I am devlopper, I can test kernel patches without problem. Thank for any idea (or patch). Olivier

Re: [LAU] An appeal to famous artists?

by Aurélien Leblond

> My question/answer: "How much are you willing to do to make it happen?" Well I'm not exactly sure anymore to be honest, I didn't think my message would start such a rant! But after reading all the answered, two things seem to stand out: 1. A lot of the FOSS music software are not for the general public. I wouldn't agree myself (I mean, Ardour, Hydrogen or Yoshimi are as straight forward as a music software can be)... And for that, nothing much I/we can do but participate to the code (which I do when I can), make donations (which I do every year), provide feedback, provide bug reports, etc, etc, etc... And obvisouly use the software and produce some tunes! Which I do too: http://soundcloud.com/a-violent-whisper (Although now I realise that nowhere I say that it's completely recorded/produced with only FOSS softwares!) 2. More interrestingly, the "appeal to famous artists" didn't seem to be well received... What seems to come out though is that although the FOSS community seems to be good to produce software, we don't seem to be good at advertising it :) - Ardour has...49 followers on facebook... Nothing on the wall... - Hydrogen...94...and one entry on the wall... - Couldn't find a # tag for any of these on Twitter... I know I know, we are not advertisers, we are developers! But what if a small group of us (and yeah, including me :)) would do that? How do we go about that? We have loads of website/tools to share code and software (sourceforge, svn, git, etc..), but none to organise ourself into a community to create some kind of organised campagn of advertisement on social networks (or other tools)! What I have in mind is what was done by ThisOneIsOnUs... what they did for their production is exacty what we do every day for FOSS software... Any ideas? > -Mike Mazarick > > PS - sorry for the top posting, but I thought it better in this instance > > >> -----Original Message----- >> From: Aurélien Leblond [mailto:blablack@gmail.com] >> Sent: Monday, August 01, 2011 11:07 AM >> To: linux-audio-user(a)lists.linuxaudio.org >> Subject: [LAU] An appeal to famous artists? >> >> I'm writing this post because of a few experiences I had over the >> years into world of amateur music production (but I'm sure it does >> applies to every artistic domains). >> >> I'm an amateur musician and a Linux enthusiast, and even though I work >> as a developer, my professional activity doesn't directly have >> anything to do with both these >> domains (although in the case of Linux this is quite a shame, but >> that's another subject).

[LAU] Wav loop points

by Louigi Verona

*Wrote this some time ago to the list, never got a reply. Now looking through the archives, I don't see this mail at all. I did attach a file, so maybe it was filtered. This is why I am duplicating this.* Hey fellas! I notice that no Linux samplers seem to support wav file loop points. All Windows DAWs that I have used support the format and there are a lot of samples out there with perfect loop points which is very useful. I have no idea whether this is part of the spec or not but these looppoints have been used for more than 15 years, that's for sure, since some of these sample collections have been around during tracking days. I did find something on loops here: http://www.sonicspot.com/guide/wavefiles.html But I think you, devs, know better than me anyway. I think it would be great if LMMS, samplers like Petri-Foo would support this, as this adds a lot of functionality. Many sample collections provide perfect loops and it is tiresome to have to try to remake it by hand each time, while in some software it is simply impossible at all. What do you think? ps: I can provide you with a sample example with loop points

[LAU] Raspberry Pi and real-time, low-latency audio

by Jeremy Jongepier

List, I've created a Wiki page with my findings of using real-time, low-latency audio on the RPi: http://wiki.linuxaudio.org/wiki/raspberrypi It's not complete and the RPi needs some more hacking to squeeze out the last bits of processing power that can be dedicated to things like samplers, synths, effects and guitar amp emulators. Thought I'd share the link, saw some questions regarding the RPi pass by the last few months. To show off what the RPi is capable of: http://www.youtube.com/watch?v=u6XKaRe_MEA&webm=1 (if you still use Flash remove '&webm=1') Regards, Jeremy

[LAU] Some new Bach

by Julien Claassen

Hello everyone! So I had a holiday in paradise. Meaning: I was surrounded by a very good friend, loads of vintage equipment and Ardour3. And I am grateful for all three. So I used a few minutes to record another piece of Bach. It's the B Minor prelude (once again) played on an ARP Pro Soloist (trumpet) and an ARP Oddysey. Unfortunately I had to spread my arms to the left and right playing the piece. So the performance is not as good, as you might wish. Still it was an experience I loved and so I'm sharing, hoping that a few gear nerds might get something out of it. http://juliencoder.de/bach/BWV869A-Prelude_in_B_Minor-Synth_Version.ogg And for the ogg-less (poor bastards :-) ) http://juliencoder.de/bach/BWV869A-Prelude_in_B_Minor-Synth_Version.mp3 Processing consists of some high and lowpass filtering, using the GLAME filters, the TAP stereo echo of the Oddy and the CAPS Plate reverb 2x2 for teh Pro Soloist. Any feedback is welcome. I hope you can enjoy it. Warmly yours Julien ---------------------------------------- http://juliencoder.de/nama/music.html
