[LAD] Stabilising self-oscillating filters?

by Gordon JC Pearce

Something I've been wondering about recently is this - if you implement a digital filter, how do you maintain stability when it's pushed into self-oscillation? Most "real" synths seem to put out a slightly clipped sinewave when in self-oscillation. Might it be as simple as an atan() clipper in the feedback loop? Gordon

[LAD] [ANN] a2jmidid - first release (resend)

by Nedko Arnaudov

I'm resending this mail (something is very wrong somewhere). Sorry if anybody got a duplicate. a2jmidid is daemon for exposing legacy ALSA sequencer applications in JACK MIDI system. It is based on jack-alsamidi-0.5 (jackd alsa seq midi backend) by Dmitry Baikov. The main purpose is to ease usage of legacy, not JACK-ified apps, in JACK MIDI enabled systems. It is tested, and works, here, with current SVN jack. ATM it may or may not work with other variants. Planned features/improvements: * One JACK client per ALSA sequencer client * Improved build system (autotools) and support (better handling) for other JACK variants (older MIDI API variants, jackdmp) * More control on what ports to bridge (currently bridging is fixed to non-hardware ports). * Real daemonization with log file, init.d script, etc. If someone wants to contribute please, contact me, or send patches, or request inclusion (Gna! a2jmidid project). As usual, packagers are more than welcome too. Homepage with screenshots: http://home.gna.org/a2jmidid/ Tarball download: http://download.gna.org/a2jmidid/ -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

[LAD] New version of nekobee

by Gordon JC Pearce

Hi folks I've just released a new tarball of nekobee, my TB-303 plugin for DSSI. Changes between 0.1.5 and 0.1.6 are: * the configure script doesn't look for gtk1.x any more (thanks Juuso Alasuutari) * the release times of the envelopes are tweaked to eliminate an unattractive bloppy noise on note off with certain keyboard controllers * the volume has been reduced to around 1/5 of previous versions (in line with other DSSIs), and an atan() waveshaper has been added to give it a bit of crunch and rein in the excesses of the resonant filter * the filter parameters have been tweaked to more closely reflect the sound of the "18dB/oct" filter in the 303. Try it out, have fun, and let me know if you run into any problems. Or in fact, let me know if you *don't* run into any problems ;-) Gordon

[LAD] [PATCH] lash: robustify alsa-sequencer event reception

by Karsten Wiese

Hi, trying lash-0.5.3 here, weired things happened: I set up a simple project with only 1 lash_synth, the lash_synth was connected to an alsa-sequencer keyboard port and to jack. After saving, closing and restarting that lash-project, the alsa-sequencer connection wasn't restored, until I launched an innocent "aconnect -il" in an other terminal. Funny, no? Reason is I think, that after polling for alsa-seq events, always only 1 event was red via snd_seq_event_input(). Attached patch cures & simplifies things by avoiding the poll() call and using pthread_cancel() to stop the thread. Karsten

[LAD] Embedded linux board

by Florian Schmidt

Hi, i'm kinda sorta in a way planning to build my own effects box. And i'm looking around for embedded boards + cpu's + fpu's which would have the required performance to be able to run some "simple" effects like FreeVerb, some compressor etc (of course with low latency of 16 frames/perdiod or something).. Any hints/suggestions? Regards, Flo P.S.: I was looking at this baby: http://www.glomationinc.com/product_9302E.html For 65$ (ca. 50 euros) it looks lie a bargain, but it seems its FPU is supported by gcc only with a patch. And i'm also not sure how much processing power this MaverickCrunch has [FLOP numbers are hard to find].. -- Palimm Palimm! http://tapas.affenbande.org

[LAD] Re: Embedded linux board

by Ben Loftis

The Epia 5000 soundcard works at low latencies, but the sound quality is not very good. The M-series has "decent" onboard sound. I think it has less to do with the digital side than the analog... the M-series has more "oomph". I'd try the 600 MHz fanless version. It should be plenty of horsepower to do stomp box processing. It's been out a long time; everything should work right out of the box with any recent distro. Tell us how it goes, Florian! -Ben Loftis
