[linux-audio-dev] ScoreChaser -- a new music notation editor

by Michelle Donalies

I recently began work on a new music notation editor called ScoreChaser. A prototype release can be found at sourceforge.net/projects/scorechaser. Its intent is to be a program in the vein of Rosegarden (and indeed, it borrows quite heavily from RG, at least in these early versions), but with groupable tracks, tablature support, and (eventually) multiple simultaneous time signatures. It's currently just an initial release with very limited functionality, but it does demonstrate the groupable tracks and the beginnings of tablature support.

[linux-audio-dev] Sample Rate Converter Comparison

by Erik de Castro Lopo

Hi all, SecretRabbitCode was recently included in a test of a number of commercially available sample rate converters and while it wasn't the best, it certainly didn't disgrace itself either. The results are here: http://src.infinitewave.ca/ This test gives me yet more incentive to continue my work on coming up with a new improved algorithm.

Fwd: [linux-audio-dev] Sound processing objects architecture, is it possible?

No you don't. A LV2 VST loader would be a single shared object, so the OS would only load one instance of it. > Then, it is quite absurde from the user point of view to open a plugin > which lets you open other plugins... it's just illogical! It doesn't look like that to the user, they will just see a list of plugins, some of which will be VST and some will not be. Have you tried the DSSI VST reflector? It would work the same as that. > Don't misunderstand me, LV2 is great, I think that it's the best > processing architecture out there, but it's designed with a 1:1 > relationship in mind (one plugin = one effect).

The terminology is confused, not least in the spec documents, but a single .lv2 "plugin" can host multiple effects with different ports and so on. - Steve

[linux-audio-dev] Back in the land of the connected

by Steve Harris

Just a quick heads-up. As some of you may know, I recently left my old job and the University of Southampton. But, I forgot to fill in the paperwork to keep my old accounts, machines etc. Consequently my @ecs.soton.ac.uk and @plugin.org.uk addresses stopped working, and the server that was running plugin.org.uk went offline. I now have my email accounts back. I'm still fishing through the backlog, so if you sent anything and I haven't replied, give it a week or so then try again. Some stuff will have been lost. Plugin.org.uk is back online at a new server, but judging by my inbox some things aren't working right. I'll look at it over the next day or so. - Steve

[linux-audio-dev] Little advertisment ;P

by kind king knight

I am an electronic musician (even an computer musician). I am specializen in any kind of electronic music from techno to glitch .Here are some of my releases: www.ccmixter.org/media/people/game_core I am also a regular participator of soundevotion (www.sdcompo.com)tracking competition (as crosfire) I mainly use trackers (renoise,fasttracker, sakale), but have experience in modular synthesis (reaktor, buzz, arts builder), midi/audio/vst sequencers (cubase, logic), and other (rebirth, reason, and many others). The point is that if you have developed an music application (linux, or windows), and need demo songs, or a simple testing, then I am probably interested:). I know that most of open source audio developers are also musicians, and they do the demo songs, and bug testing, and other things by themselves, but there not always is time. Anyway I am here to help you! :D

Ok, Apparently forum addicts have decided to hijack this thread though, the original question was : do you want LA* _lists_ (LIST is the keyword here, can't stress it enough) to be moved to linuxaudio.org. I have noting against the idea of a forum, the people interested in this are free to build and maintain one and eventually discuss it with Ico.

[linux-audio-dev] LAD/LAU/LAA/Consortium/...

by Predrag Viceic

Hi, Sorry for crossposting, which is intentional. See below ;) I personally think that this multiplication of LA lists is not a good thing. The idea, proposed by Ivica, which politely suggests the migration of all those lists to an unique one seems very good to me. I would even suggest the usage of a forum (à la php-forum) for information sharing. Those forums would allow multiple topics (LAD, LAA, LAU, Ardour, Rosegarden, MuSE, Jack, ... ) and in the same time facilitate the research, the tracking of topics and the most important thing, would allow the linux newcomers to see all the work done in those lists. I hope that I'm not irritating anyone by suggesting the above, but we are all conscious of the fact that linux audio is still a niche "market" so having an unique point of access to the posts would really be awesome.
