Devs needed for opensource virtual analog softsynth idea

by Sascha Schneider

Hi folks, inspired by a plan of a german onlinemag called amazona.de I came up with the idea that a virtual analogue opensource softsynth nativly running on Linux would be really nice. (a nice filterbank too, but thats another thing) Amazona planned a complete synth based on userpolls (only in german, sorry): http://www.amazona.de/index.php?page=26&file=2&article_id=3191 which is now realized as vst: (only german, too) http://www.amazona.de/index.php?page=26&file=2&article_id=3202 I know that Zynaddsubfx/yoshimi has a really strong soundengine and I asked myself, if it would be possible to take this engine or the DSSI-API and build a polyphonic softsynth with a nice UI like the new calf plugins or guitarix, a bit like the loomer aspect, with some discoDSP, a bit from the Tyrell or the Roland Gaia SH-01 with midilearn, ...... The problem I have are my programming skills, that are not good enough to code this kind of software by myself. Are there some LAD's willing to join/take/realise this idea?? If there is interest I could translate the ideas of amazona.de and we all could share our visions for a new kind of controllable virtual analogue softsynth. kind regards, saschas

kokkinizita

by Fons Adriaensen

Hello all, As posted before, kokkinizita.net went offline last week as the result of some stupid but apparently uncorrectable issues with my hosting service, hosteurope.de. They are flatly refusing to put the site back online or allow me to create a new one. The kokkinizita.net domain will appear again (I still own the domain name), but this could take some time. Meanwhile the site has been recreated at <http://kokkinizita.linuxaudio.org>. You won't be able to access it until linuxaudio.org's DNS will be updated to include this url, which will happen some time friday. In the meantime, if you need something urgently, just add the line kokkinizita.linuxaudio.org 198.82.152.114 to your /etc/hosts, but don't forget to remove it later. Many thanks to Robin Gareus, Ico Bukvic and Virginia Tech for providing this solution, and also to all people who suggested alternative hosting. For email, please use the from: address of this message, not the gmail one I posted earlier (I'll still check it, but not as frequently as I do now). Ciao, -- FA

Petri-Foo - have your say!

by James Morris

Hi, I've forked the Specimen sampler to create Petri-Foo[1]. The main goal of Petri-Foo was to make the ADSRs and LFOs independent from the items they modulate (ie amplitude/pitch/etc). This has been achieved and is quite nice to play with switching modulation sources on the go as a sequences plays and the output is recorded. I'm currently overhauling the sample-'editor'. So far I've ported the deprecated GDK drawing code to Cairo, and prettified the display of play start/stop and loop start/stop points and areas. What I want to do next is explained here Sample editor zoom [2] Your ideas would be welcome in how it should work. I'll try and implement it. If you're interested subscribe to the Petri-Foo-Devel list[3]. Please note though, it's not ready for general usage by inexperienced users who don't know how to download and compile software from git repo's nor for users who aren't expecting things to be broken. Thanks, James. [1] http://petri-foo.sourceforge.net/ [2] http://sourceforge.net/mailarchive/message.php?msg_id=27069524 [3] https://lists.sourceforge.net/lists/listinfo/petri-foo-devel

Allocating 96 but reading 16 (multple times)

by Jens M Andreasen

The other day I tried somthing unusual. I use 96 frame buffers and so I allocate two of those for each of in and out, and then read/write (blocking) 96 frames at a time - makes sense, yes? Well no, it turns out that - without doing any processing - looping over read/writing only 16 frames at a time is more robust. How come? The same effect can be observed with 64 frames and 16 appears to be the optimal value in the loop. /j

Advice sought on project hosting and version control

by drew Roberts

I am working on a rewrite (complete along with a rename) of my old soundwall application. I hope for this to be a jack app at some point soon. I hope to make an initial release this weekend. I am seeking advice on project hosting sites. I am also seeking input on version control. Anyone using git and Gitorious for this? (I have no experience with git really but would be willing to learn it for the purposes of this project if it makes sense.) all the best and thanks in advance, drew -- http://freemusicpush.blogspot.com/

confusion over specimen svn and specimen in AUR

by James Morris

I forked Specimen into Petri-Foo. Trouble is, I don't recall which version! I have a Specimen SVN from the Arch User Repository (AUR) Specimen SVN from zhevny.com And of course, Petri-Foo which doesn't seem to bear exactness to either of these (that is the parts of Petri-Foo which I haven't yet altered). This makes giving patches back kinda difficult. The version of Specimen I have installed system wide (who knows where it is from?) has spin buttons in the sample-editor for editing the sample play/loop positions explicitly. The version of Specimen that I forked Petri-Foo from did not (have the spin buttons) so I copied them from (??? the specimen-build sub-dir obtained via the AUR ??? ru sure?? ??). The version of Specimen - r89 - from zhevny.com doesn't have the spin buttons - unless it's in a "secret" branch which isn't default (i don't have a clue how to 'browse' these things). Consequently I have various diffs which maybe you can make sense of. By some magic manipulation, you'll find either a) a new feature providing explicit sample play/loop position editing via spin buttons - or - b) a fix for the existing explicit sample play/loop position editing via spin buttons which prevents the loop start/stop positions from being incremented/decremented past the play start/stop positions. Hope it helps someone. If anyone can shed any light on the confusion I'd be grateful, thanks. James. -- _ : http://jwm-art.net/ -audio/image/text/code/
