[linux-audio-user] [ANN] DSSI 0.9.1 release

by Sean Bolton

Announcing the DSSI Soft Synth Interface version 0.9.1 release: http://dssi.sourceforge.net/ DSSI is an audio plugin API for software instruments and effects, based on LADSPA, the ALSA sequencer event types, and OSC (Open Sound Control) communications. This release does _not_ contain any changes to the DSSI API itself, which has been stable now since the 0.4 release fifteen months ago (with minor additions at 0.9). Instead, it contains numerous clarifications to the specification and documentation, and the included reference host and example programs have become significantly more robust. Specific changes in 0.9.1 include: - The distribution now has a full autoconf/automake/libtool build system. - FluidSynth-DSSI has been moved into its own package, and no longer depends upon the FluidSynth source. - The reference host, jack-dssi-host, now supports plugins with audio inputs, as well as LADSPA-only plugins (with or without custom DSSI GUIs.) Available hosts and plugins --------------------------- More exciting than the changes in this release, is the recent growth in DSSI implementations. Items marked with '*' are new since the DSSI 0.9 release. Available hosts are: - jack-dssi-host, included in the DSSI distribution - the Rosegarden 4 sequencer * Om, a modular synthesizer * ghostess, a lightweight GTK+ host * dssi~, a Pure Data external Efforts are underway to add DSSI hosting to: - the MusE sequencer * Csound5 * GNU Classpath Available plugins include: - the simple synths and sampler in the DSSI distribution - FluidSynth-DSSI, a soundfont-playing plugin - Xsynth-DSSI, an analog-style synth - dssi-vst, a wrapper plugin enabling the use of many Windows VST plugins - hexter, a Yamaha DX7 modeling plugin * ll-scope, an oscilliscope plugin * Sineshaper, a waveshaping soft synth * dssi_convolve, a DSSI wrapper around libconvolve * xy-controller-dssi, a GUI controller plugin which translates mouse input into X-Y control outputs * WhySynth, which offers a number of synthesis methods The Future ---------- In the year and a half since its initial introduction, DSSI has met a number of challenges to its adoption: the continued (perpetual?) forthcomingness of GMPI, apprehension about adopting a standard with 'Disposable' in its name, some "wait and see if takes off" attitude, and numerous gripes that it won't do this or can't do that. Even so, the creative potential available through DSSI today is great. In part due to this success, there has been a noticable commitment voiced in recent discussions on the DSSI email list to keeping any future enhancements backward-compatible with the existing DSSI API. In the author's opinion, this indicates DSSI will continue to be a stable API, at least until such time as a '2.0' version is considered. With regard to possible future enhancements, interest has been highest in two areas: providing plugins with transport position and tempo information, and allowing plugins to send MIDI data. If you're interested in helping shape these or other developments, please join us on the DSSI discussion list.

[linux-audio-user] Fwd: ALSA problem: No such device ??

by J Wang

I'm trying to get ALSA 1.0.9b up on a VIA Epia with an onboard VIA 8233 soundcard. I know the hardware is there because dmesg says: ----- Via 686a/8233/8235 audio driver 1.9.1-ac3 ac97_codec: AC97 Audio codec, id: VIA97 (Unknown) via82cxxx: board #1 at 0xDC00, IRQ 10 Enabled Via MIDI ----- These messages come from via82cxxx_audio.c (I'm using the 2.4.26 kernel). Furthermore, I can "cat foo.au > /dev/audio" and hear sound, and even mpg123 "foo.mp3" works - so I know the hardware is OK. I ran snddevices and so the /dev nodes are there. But when I try to load the module with "modprobe snd-via82xx" it loads many modules but ends with: ----- insmod: init_module: snd-via82xx: No such device modprobe: failed to load module snd-via82xx ----- lsmod says: ----- root@june 22# lsmod Module Size Used by Tainted: P snd-ac97-codec 56832 0 snd-mpu401-uart 2848 0 snd-rawmidi 12484 0 [snd-mpu401-uart] snd-seq-device 3560 0 [snd-rawmidi] snd-pcm 52012 0 [snd-ac97-codec] snd-timer 13192 0 [snd-pcm] snd 29360 0 [snd-ac97-codec snd-mpu401-uart snd-rawmidi snd-seq-device snd-pcm snd-timer] snd-page-alloc 4392 0 [snd-rawmidi snd-seq-device snd-pcm snd-timer snd] ----- I'm perplexed! I've gone through the alsa.org pages several times, especially http://alsa-project.org/alsa-doc/doc-php/template.php?module=via82xx but I'm still stuck. If anyone has any suggestions, I'd be really happy to hear them! Thanks, Jim tc4312(a)yahoo.com > __________________________________ > Yahoo!

[linux-audio-user] gwhere for FLAC

by Andrew Gaydenko

Hi! The aim is very simple: I have plenty of (tagged) FLAC files and would like to archive them on CDs/DVDs. I have googled for some kind of "removable media catalog manager" and have found the gwhere (www.gwhere.org). It's nice. Now I'm looking for something like "gwhere with FLAC support". I mean a capability to scan-disc/seacrh-catalog using FLAC tags too. Does anybody know something useful for this aim? Thanks in advance! Andrew

[linux-audio-user] Short movie with music

by norv

Hi all, Here's a link to a short movie I made called "Daisy Hill". I did the music as well. http://www.longforest.com/index.php?set_albumName=Daisy&option=com_gallery&… I shot the movie on my digi still camera in movie mode and edited it in Cinelerra on debian-amd64 sid. I used Hydrogen for the drums, Ensoniq ASR10 sampler for bass and trumpet, and guitars thru ASR10 as pre-amp. Recorded in Ardour. Movie sound mix in Cinelerra. The web movie is 2:18, 8.2MB, Windows Media compatible I didn't spend too much time on the music as the audience was impatient. I transferred the 320x240 10fps web clip to PAL 720x576 48kHz stereo and burned it to DVD with a menu etc. The quality is quite good considering the original format. Cheers, Norv

Yes, that was exactly the problem. I put 127.0.0.1 lounger.tydrwg.org into /etc/hosts and it all works perfectly. Now to spend some time scaring the cat with my Rick Wakemen impressions on Whysynth.

[linux-audio-user] software playing in swing rhythm

by mh

Hi, I am new to this list, but absolutly not new to midi. I have a demundi installation on my computer and I like to make some arrangements for choirs. With windows there are two programms which can play midis in swing rhythm (as far as I know): Finale ( $ ) and anvilstudio (free/shareware). I used the later, but unfortunately itwas/is buggy and I lost often files after hours of work :-(. On the other hand it was the software which without its bugs would fullfill my needs quite good. So now I am with linux and looking around ( I began nearly one year ago ! ) for software fullfilling my needs. And there are two diffrent problems which havew to be resolved. 1) playing in swing rhythm while composing without the need to note swing 2) a sofisticated midi player for exercises and rehearsal To 1) What software does the trick now? I have heard that rosegarden4 (newest cvs?) has some swing support. If so, does someone know how it is used, what it does? Whats about brahms or muse_score? As there are no debian packages out there and as I have never compiled a single package I would like to know whether or not one of these programms would fullfill my needs? Which other software can you recommand? To 2) There are many midi players out there which do more or less all the same. Having one of them, you can throw away the rest. But there seems to be no application which really deals with the possibilities of midis for rehearsal purposes. And sequenzers will never be focused on playing. Therefore I am looking for a project in development which aims to a player only application, but a soffisticated one? I have my ideas quite clear and I know how much one could learn with an application like the one proposed and searched by me. Should I better ask in the developement section? Greetings from Germany michaa
