You're referring to http://www.jrigg.co.uk/linuxaudio/ice1712multi.html? I'm new to the multiple Envy24 cards world, since some weeks I've got a second card, but I also had a time out.

TerminatorX on Gitorious

by Gerald Mwangi

Hi Guys, I'm proud to announce my first project on gitorious: TerminatorX. I took the code from the old project site, and have done some heavy recoding: The entire audio part: -Now tX relies exclusively on JACK, and I intend to keep it so. -New mixer behind the scene: All Turntables are stereo, you can still load mono files and the stream will be copied to the left and right. This is intentional, since it allows to use stereo Plugins on mono files (some sweet LADSPA plugins are only i stereo). -Mono plugins are also usable, their output is simply doubled -Extra stereo outputs per Turntable -Support for Rubberband, tempo of client turntables can be autosynced to the master turntable. - Exclusive use of sndfile -Rewriting of the sequencer part, not all is functional There is lots to do: -profiling, since tX crashes sometimes (actually many times:)) - throw out old C code, where its possible: tX relies on C-style Gtk, which is a pain in the neck for a C ++ programmer like me. - there are many C-extern functions. To hell with them, they are bad coding style. - the gui still displays one channel, also for stereo files. - the sequencer has to be checked, fixed. I actually would like to redesign it, but more later. - the save and load routines have to be checked, since I added some parameters which are not yet saved/loaded All in all tX needs a redesign in 3 integral parts,ordered by priority: -The sequencer (tX_seqpar) is a mess. I even didn't really bother to look that deep into the code. As I understand it, it just records changes of the parameters, then replays them. I think this could be done easier, and in strict C++ style. I need some ideas on how to construct a good model. -The Load and Save routines: I would like to convert all classes to serializable ones!! This is more transparent, and would allow for nice things like network sessions (Imagine tX on multiple PCs running with netjack, and saving the session to one instance on one PC!) -Last but by far not least: The GUI. If you look at the code, you see that Alexander did not make a clear line between the GUI and the engine. I think this is important, for stability reasons. Second, its C-Style Gtk and not portable. So the plan is to open another branch, in order to rework the GUI so that a) It is at least codewise seperated from the engine (e.g extra namespaces). b) It's pure C++ and c) its portable. I think the only choice there is, is to switch to Qt, but I'll leave that open for discussion. So hope you get in and grab the code at http://gitorious.org/terminatorx . Theres no configscript, you have to change the makefile to you needs. Lets revive this wonderfull program. Gerald P.S Sorry for the poor documentation !!

Envy24control uses the same mechanism as your system does (see /etc/asound.state and amixer(1)) to save the state of your ALSA devices between boots. The difference is this mechanism puts the file under your control at ~/.envy24control/profiles.conf and allows you to set eight different profiles: allowing you to save or restore up to eight different "asound.state"-like configurations per card. The different profiles are most useful for storing routings set in "Patchbay/Router" panel, as well as "Hardware Settings" panel clock rate, or external SPDIF/wordclock sync. On cards with switchable spdif/optical ins (Terratec/Terrasoniq), you can persist this extra level of "routing" -- which is useful for "matrix routing" between two digitally-interconnected and sync'd computers. ( I use profiles named: 44dmix-to-1&2&spdif, 48dmix-to-1&2&spdif, spdmix-to-1&2&spdif, 44all-outs-pcm, 48all-outs-pcm, spdif-all-outs-pcm, 96dmix-to-1&2&spdif and 96all-outs-pcm. ). When you have a combination of settings in envy24control that you want to return to, just go to the "Profiles" panel, enter the name of the profile into the first free text field (initially these will be numbered "1" through "8"). After entering a descriptive name, click "Save active profile." To restore a given profile, just click on the "button" area surrounding the text field, or even click within the text field. You'll notice the selected profile "button" indicates activation via coloration. After changing profiles, go to, for example, Patchbay/Router or "Hardware Settings" panels,and note that the previously saved state was restored. Note that significant amounts of setting data gets saved in these files: > ll ~/.envy24control/ -rw-r--r-- 1 npm npm 115253 2010-08-07 23:10 profiles.conf For comparison: > ll /etc/asound.state -rw-r--r--. 1 root root 128079 2010-08-07 18:15 /etc/asound.state (That's for a system with two envy24-based cards installed, thus size is large, causing "save" to produce a brief but noticeable pause in the metering on a slower system or "ondemand" throttled system). Niels http://nielsmayer.com PS: speaking of envy24 anybody know whether this will work in standard alsa/linux: http://www.lionstracs.com/store/msaudio-board-envy24-p-122.html and are those i2s connectors, or ttl-level spdif? i guess if it's i2s you have to get: http://www.lionstracs.com/store/mixer-board-p-210.html (which looks pretty cool, esp w/ the onboard dream-based hardware synth w/ large sample ROM).

mudita24 1.02 -- improved envy24control mixer/router for ice1712-based sound-cards

by Niels Mayer

The "Mudita24" package is a modification of alsa-tools' envy24control: an application controlling the digital mixer, channel gains and other hardware settings for sound cards based on the ice1712 chipset ( http://alsa.cybermirror.org/manuals/icensemble/envy24.pdf ). It also displays a level meter for each input and output channel and maintains peak level indicators. This utility is preferable to alsamixer(1) for those with ice1712-based cards: M-Audio Delta 1010, Delta 1010LT, Delta DiO 2496, Delta 66, Delta 44, Delta 410 and Audiophile 2496. TerraTec EWS 88MT, EWS 88D, EWX 24/96, DMX 6Fire, Phase 88. Hoontech SoundTrack DSP 24, SoundTrack DSP 24 Value, SoundTrack DSP 24 Media 7.1. Event Electronics EZ8. Digigram VX442. Lionstracs, Mediastaton. Terrasoniq TS 88. Partial support for Roland/Edirol DA-2496. Now available, version 1.02: source: http://nielsmayer.com/envy24control/mudita24-1.0.2.tar.gz binary: http://nielsmayer.com/envy24control/mudita24-1.0.2.x86_64.tgz patch: http://nielsmayer.com/envy24control/mudita24-envy24control-0.6-to-1.0.2.pat… 'envy24control' is part of the "alsa-tools" package. For example, under CCRMA's Fedora repos, it's part of alsa-tools-1.0.22-1.1.fc12.ccrma.x86_64. This "mudita24" package updates/replaces the alsa-tools /usr/bin/envy24control application. The default "./configure ; make ; sudo make install" process on the source-code leaves a binary in /usr/local/bin/envy24control and places the man-page in /usr/local/man/man1/envy24control.1 . This means you can still use the standard alsa-tools version in /usr/bin/envy24control .

External MIDI control of the hardware mixer via --midichannel and --midienhanced options unaffected by this change. * For M-Audio Delta series, add display of "Delta IEC958 Input Status" under "Hardware Settings." * Command line options --no_scale_mark, --channel_group_modulus affect layout and presence of dB markings for sliders. --channel_group_modulus allows override of Left/Right grouping of dB labels for multichannel applications. * Control of peak-meter coloring via --lights_color and --bg_color options. Reasonable default colors used when these options are not set. (1.0.1's use of Gtk skin to provide an automatic color choice didn't work out that well on some systems.) * Fixed command-line options --card and --device to allow valid ALSA card and CTL device names ( https://bugzilla.redhat.com/show_bug.cgi?id=602900 ). * Profiles created in ~/.envy24control and not "~/envy24control" ( http://bugtrack.alsa-project.org/alsa-bug/view.php?id=4738 ). Summary of previous updates from envy24control 0.6.0 (GIT HEAD) to "1.0.2": (1) Implemented "Peak Hold" functionality in meters; reimplemented meters to do away with inefficient "faux LED" peak-meter display. (2) Significantly reduced the number of timer interrupts generated by this program by slowing down all updates to 10 per second -- previously meters updated 25x/second! (3) All volumes are represented as decibels, including the 0 to -48dB range of the hardware peak-meters, the 0 -to- -48dB&off attenuation for all inputs to the digital mixer, the 0 -to- -63dB attenuation of the analog DAC, and the +18 -to- -63dB attenuation/amplification of the analog ADC. (4) All gtk "scale" widgets have dB legends; the "PageUp" "PageDown" keys allow rapid movement between the marked levels, and "UpArrow" and "DownArrow" allow fine-adjustment. Niels http://nielsmayer.com PS: Why "mudita24" ? An alternate name to avoid confusion with "envy24control 0.6.0" until changes in this version propagate upstream. See http://en.wikipedia.org/wiki/Envy#In_philosophy "In Buddhism the third of the four divine abidings is mudita, taking joy in the good fortune of another. This virtue is considered the antidote to envy and the opposite of schadenfreude."

announcing envy24control, mudita (*) edition.

by Niels Mayer

Summary of updates from envy24control 0.6.0 (GIT HEAD) to "1.0.0": (0) After a decade, incremented version to 1.0.0 (**) (1) Implemented missing "Peak Hold" functionality in meters and reimplemented meters for increased efficiency and lower X resource usage. (see http://www.linuxaudio.org/mailarchive/lad/2010/7/12/171535 & https://bugzilla.redhat.com/show_bug.cgi?id=602903 ) (2) All volumes are represented as decibels, including the 0 to -48dB range of the hardware peak-meters, the 0 -to- -144dB attenuation for all inputs to the digital mixer, the 0 -to- -63dB attenuation of the analog DAC, and the +18 -to- -63dB attenuation/amplification of the analog ADC. (3) All gtk "scale" widgets have dB legends; the "PageUp" "PageDown" keys allow rapid movement between the marked levels. (4) Got rid of myriad compile warnings and other minor fixes across codebase. Some screenshots: http://nielsmayer.com/envy24control/Screenshot-Envy24Control-AnalogVolume.p… http://nielsmayer.com/envy24control/Screenshot-Envy24Control-MonitorInputs.… http://nielsmayer.com/envy24control/Screenshot-Envy24Control-MonitorPCM.png ------------ To the ALSA project: please consider this patch to alsa-tools' envy24control (**): http://nielsmayer.com/envy24control/envy24control-0.6-to-1.0.patch (patch to 'envy24control' from GIT trunk/head of alsa-tools) http://nielsmayer.com/envy24control/envy24control-1.0.README (summary of changes from 0.6.0 to 1.0.0) ------------ Those wanting to compile directly, or run a 64 bit linux binary I've built: http://nielsmayer.com/envy24control/envy24control-1.0.tar.gz (full directory, just follow README directions to build/install) http://nielsmayer.com/envy24control/envy24control-1.0-fc12-x86_64.tar.gz (x86_64 binary that should work on fedora12 and equivalent OpenSuse release) I'd appreciate any testing results or comments on this "1.0.0" release. In particular, I'd like some assurance that the dB markings on sliders in "Analog Volume" panel are correct (compared to values reported by 'alsamixer'). I'm looking for testing with following devices (as I think my testing covers code for M-Audio Delta 44 & Delta 66, Terratec Dmx6fire & EWX2496) specifically: M-Audio Delta 1010, M-Audio Audiophile 2496, M-Audio Delta 1010LT TerraTec EWS 88MT, TerraTec EWS 88D, TerraTec Phase 88, Hoontech SoundTrack DSP 24 (all variants).

[LAA] [ANN] guitarix-0.11.0 released

by Andreas Degert

On behalf of the guitarix team I'm proud to announce Guitarix Version 0.11 Guitarix is a simple Linux Rock Guitar amplifier and is designed to achieve nice thrash/metal/rock/blues guitar sounds. Guitarix uses the Jack Audio Connection Kit as its audio backend and brings to the jack audio graph a mono amplifier input/output port, and a FX mono input with two (stereo) output ports. Guitarix provides a jack midi input port to connect a midi controller (midi learn) and a (3 channel) jack midi output port, feed by a (scalable) mix of the tuner and a beat-detector. Release 0.11.0 comes with following changes : Users visible changes: - new version of the impulse response parameter editor. You can now graphically define a gain line to be applied to the IR data, e.g. emphasize a part of the early reflections or damping the reverb tail to make it fit to your guitar sound. - the multi-line distortion effect now has 4 frequency bands and is better optimized - fix regression from version 0.10.0: now the default preset file is created again if it doesn't exist (e.g. in new installations). Changes that might be interesting for Developers: We put the Guitarix widgets into a library, with the goal of making them usable independently from Guitarix. You can build it as shared library and there's a c++ (gtkmm) wrapper, a python wrapper and glade support. Check it out and look for examples in those directories, or just build a nice looking display with the glade editor, and of course ask in our Guitarix forum (it's still alpha). As a side note, Guitarix is now in debian (unstable), of course at the moment still the previous version 0.10. have fun _________________________________________________________________________ guitarix is licensed under the GPL. Project page with screenshots: http://guitarix.sourceforge.net/ download: http://sourceforge.net/projects/guitarix/ please report bugs and suggestions in our forum here: http://sourceforge.net/apps/phpbb/guitarix/ ________________________________________________________________________ For capture, guitarix uses the great 'jack_capture' (version >= 0.9.30) written by Kjetil S. Matheussen. If you don't have it installed, you can look here: http://old.notam02.no/arkiv/src/?M=D For extra Impulse Responses, guitarix uses the zita-convolver library, and, for up/down sampling we use zita-resampler, both written by Fons Adriaensen. If you don't have it installed, get it here: http://www.kokkinizita.net/linuxaudio/index.html We use the marvellous faust compiler to build the amp and effects and will say thanks to : Julius Smith http://ccrma.stanford.edu/realsimple/faust/ : Albert Graef http://q-lang.sourceforge.net/examples.html#Faust : Yann Orlary http://faust.grame.fr/ ________________________________________________________________________ For faust users : All used Faust dsp files are included in /guitarix/src/faust, the resulting cc files are in /guitarix/src/faust-generated The tools we use to convert (post-processing and plot) the resulting faust cpp files to the needed include format, stay in the /guitarix/tools directory. ________________________________________________________________________ regards Hermann Meyer, James Warden, Andreas Degert
