[LAU] tschack ... early version of smp enabled jack1

by torbenh

hi... since i dont want to let jack1 codebase die in a feature freeze, i added some features. - smp aware - clickless connections these changes are too radical to be included in mainline jack1. so it gets a new name. its approaching beta status now. dunno... maybe someone is motivated to test it. http://hochstrom.endofinternet.org/trac/tschack/wiki -- torben Hohn

[LAU] New TerminatorX release 3.83pre for testing

by gerald mwangi

Hi guys, I'm proud to announce Terminator 3.83pre for testing (http://www.set-germany.org/TerminatorX/terminatorX-3.83pre.tar.gz). Changes: support for rubberband, filehandling exclusively through sndfile, some bugs fixed and i hope none introduced :) Rubberband is used for timestretching the samples. Each turntable has now an extra 'tempo' knob to stretch/shrink the sample without change of pitch. Furthermore a tempo sync option was introduced to sync clients tempo to that of the master: Select a master -> Select one or more clients -> Press play (load some samples before ) and turn the master tempo knob and note the automatic change of the tempo of the clients. Note that the tempo is actually just the stretch factor of the entire sample since the samples aren't analized for their transients (that's the next feature!). To simplify the code, i decided to rely totaly on sndfile (http://www.mega-nerd.com/libsndfile/). That means only the formats understood by sndfile are supported. I tried to contact Alexander König, but he hasn't answered. Maybe we should pull up a sourceforge project? Looking foreward to answers, ideas and complaints. Yours, Gerald

Re: [LAU] mx44 softsynth - help!?

Is there a useful man page with the new version, I > wonder? Gwenhwyfaer, do you know the function of all the different controls? Almost. In each of the operators, you have a checkbox next to the envelope controls, a set of 8 radio buttons, a pair of checkboxes in the top right hand corner, and a checkbox immediately below that pair. Respectively, these are "waveshaper" (if checked, the wave is sent through some kind of "resonant" waveshaping), "harmonic" (selects one of the first 8 harmonics to add to the fundamental sine wave*), "complex" (I think - don't quote me - the harmonic modulates the fundamental instead of being added to it) and "lowpass" (clobber the higher harmonics produced by the operator), and "magic" (some kind of subtle detuning / phase manipulation effect - try it and see). * Of course, I say "sine wave" - the operators don't use pure sine waves; they use an extremely cheap to compute in MMX, but very rough and audibly square-ish, approximation.

[LAU] lashstudio release 3

by Marius Stoica

Hi, for those interested, there's a reworked version of lashstudio module with a new build of muse (v1.0.1) that solves an incompatibility with the 2.6.30 kernel from the main iso of 431. in other words, this release is for the "real" puppy 431 (based on sfs 4), not for the retro variants like release 2 was. some changes: besides new version of muse, there's celt support for netjack (also, since release 2, jack is build against freebob and ffado for firewire keyboard support), proper patchage icon on the menu and added some missing ladsapa. Lashstudio is a quick and dirty, lash centered, setup of applications for audio and midi. It is packed as an sfs module for puppy linux. download: http://sourceforge.net/projects/lashstudio/ website: http://lashstudio.sourceforge.net/ have fun! marius

[LAU] korg k-series controllers

by David Santamauro

Hi all, Along the lines of the axiom discussion, I was wondering if there was a way to control the korg k61 (k-series keyboard controller)? It is recognized and functions nicely but I unfortunately haven't found a way to actually control it, i.e., reassign knobs and sliders etc. and most importantly, change the transmit channel. I've tried installing the "editor" under wine but that doesn't seem to cooperate all that well as it doesn't recognize the k61 at all. I'd like to find a pure linux solution as wine is a good crutch but isn't an end solution, I fear. If anyone has experience with this particular controller, I'd be grateful. thanks David PS I hate to keep spamming this list with question after question, but I feel I'm almost there... almost ... and the closer I get, the more I am ready to get back to writing music.

[LAU] [ANN] Qtractor 0.4.5 - A Friskier Demivierge is out!

by Rui Nuno Capela

SCNR ;) mostly yet another bug-fix-regression dot release, nuff said. Qtractor 0.4.5 (friskier demivierge) is out! Change-log: - Changing loop points while playback is rolling, with the play-head any near, was leaving audio clips out-of-sync.</li> - MIDI event list view was missing some selected items with the very same onset time, now fixed.</li> - When failing to detect a SSE enabled build, the CFLAGS variables are now properly restored to their previous sane state, preventing all subsequent dependency tests from false positives (bug# 565860(a)bugs.debian.org).</li> - MIDI clip editor (aka piano-roll) multiple selection has been fixed (again) re. move/paste-snapping consistency.</li> Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: - source tarball: http://downloads.sourceforge.net/qtractor/qtractor-0.4.5.tar.gz - source package (openSUSE 11.2): http://downloads.sourceforge.net/qtractor/qtractor-0.4.5-3.rncbc.suse112.sr… - binary packages (openSUSE 11.2): http://downloads.sourceforge.net/qtractor/qtractor-0.4.5-3.rncbc.suse112.i5… http://downloads.sourceforge.net/qtractor/qtractor-0.4.5-3.rncbc.suse112.x8… - binary packages (Ubuntu 8.04 LTS; no LV2 support): http://downloads.sourceforge.net/qtractor/qtractor_0.4.5-1.rncbc.ubuntu804_… http://downloads.sourceforge.net/qtractor/qtractor_0.4.5-1.rncbc.ubuntu804_… - binary packages (Ubuntu 9.10; UPDATED): http://downloads.sourceforge.net/qtractor/qtractor_0.4.5-1.rncbc.ubuntu910_… http://downloads.sourceforge.net/qtractor/qtractor_0.4.5-1.rncbc.ubuntu910_… - user manual (ever still outdated): http://downloads.sourceforge.net/qtractor/qtractor-0.3.0-user-manual.pdf Weblog (upstream support): http://www.rncbc.org License: Qtractor is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later.

[LAU] New track and related charity compilation album

by Will Light

Last week on the monome.org forums, there was talking about putting together an album with all the proceeds going to relief in Haiti, and a call was put out for anyone who wanted to to contribute a track. I finished this one just in time to get it on the compilation and I'm quite happy with how it turned out. The album itself has some fantastic music and is name-your-own-price with a minimum of $1. If electronic music is particularly something you enjoy, I'd definitely recommend checking it out. My song is the second track on the album, "House from a Home". The album is available from http://einpuls.bandcamp.com/ Thanks, and enjoy :) -will

[LAU] rakarrack-0.4.2 is released

by Josep Andreu

Hi Rakarrack is a richly featured multi-effects processor emulating a guitar effects pedalboard. Effects include compressor, noise gate, graphic equalizer, parametric equalizer, flanger, chorus, echo with reverse playback, musical delay, reverb, digital phaser, analogic phaser, wah-wah, alien-wah, harmonizer, and three flexible distortion modules including sub-octave modulation and dirty octave up. Most of the effects engine is built from modules found in the excellent software synthesizer ZynAddSubFX. Presets and user interface are optimized for guitar, but Rakarrack processes signals in stereo while it does not apply internal band-limiting filtering, and thus is well suited to all musical instruments and vocals. Rakarrack is designed for Linux distributions with Jack Audio Connection Kit. http://rakarrack.sourceforge.net News: AUDIO: - Two new effects have been added: Analog Phaser and Derelict Distortion. - Limiter at the end of the chain. - Four new waveshape types: Crunch, Hard Crunch, Dirty Octave+ and Modulated Square improving all the Distortion effects.. - Four new LFO wave types: Ramp Up, Ramp Down, Zig-Zag, Modulated Square improving Chorus, Flanger, Phaser, Pan, etc. - Sub Octave in Distortion effects. - Reverse Echo. - Compressor support for adjustable knee, switch (Mono/Stereo), improved automatic gain function. - Global Wet/Dry (FX%) - Improvements in Wah-Wah, Tuner and Harmonizer. MIDI: - Up to 104 controllable parameters. - MIDI Learn for each preset, up to 20 effect parameters can be assigned to a single MIDI control message. - jack MIDI GUI: - Scalable Fonts - Background Image. - New Logo and Icons. - Minor things. PRESETS - 15 New Presets. - Improvements on most of the old ones. - Improved consistency between preset volume levels. DOCS: - Help updated. BUGS: - Fixed data problem with Big Endian architectures, now rakarrack runs properly on PowerPC and maybe others. - Fixed important CPU usage bug related to computation of denormal numbers. - Other minor bugs fixed. -- Josep Andreu <holborn(a)telefonica.net>

[LAU] hdsploader and Fedora 12

by Joe Dell'Orfano

Hi all, I am testing fedora 12 on my 64-bit system using Planet CCRMA repositories. Everything boots and runs (even RT kernel) except my multiface II. On Fedora 8, the Multiface generally initialized at the udev phase of bootup. I say "generally" because at times it doesn't initialize, requiring several power off cycles. Interestingly, once the firmware is loaded by FC8, if I then boot into FC12 (I have it set up as a dual boot system in order to maintain my working production system), hdspmixer crashes (although hdspconfig works). It seems that the FC8 firmware remains loaded (perhaps an older version of the alsa firmware). When I am in FC12, hdsploader fails with a "device busy" error. The multiface II is running off of PCIe on IRQ17, which is apparently shared with my Radeon card, also in PCIe port. I cannot reassign this IRQ in BIOS, and I haven't been able to plug into another PCIe port. Any help? Is there some FC12 udev magic I must do? Thanks! -Joe Dell'Orfano
