No. The left-to-right level-bars imply a left-to-right movement to change the values. And one of the reasons to do the color-thing is space. If I hide the text and only show it when the mouse hovers, I can fit a lot of mixing-nodes on screen. A horizontal (or vertical) bars needs more space to have a comparable resolution. I like the idea of hiding the mouse during value-changing moves. I already have these "sliders" react to the mouse-movement logarithmic. That also helps a lot when both coarse and fine changes should be possible with similar mouse- movement. And somehow I dream of a toolkit where you select a knob/slider/fader and it then reacts to the turn-knob you have on your desk. But given the variety in toolkits, I think this is a dream of the distant future unless that big knob sends out mouse-movement signals... Have fun, Arnold

Fwd: Mouse/knob interaction

by alex stone

So far, nobody's mentioned how to get to the aforesaid knob in the first place, or alternatives to manipulating it. Navigating with the mouse is a poor second to precise locating, and using qwerty actions to set values, be it a knob or slider, is more accurate. So, tab, or an associated action to get to the knob in the first place, and something like ALT+ up/down arrows (as an example) to change the knob value. Then it's irrelevant whether the knob responds to mouse up/down/left/right, or mouse wheel, for users who find those options second best, when a more efficient and precise option already exists. For graduated speed in the case of a spin knob (starting slow and getting faster), the user only needs to keep the actions pressed.

EMutrix v0.1 released

by Camilo Polymeris

Hello EMutrix is a simple, easy-to-use graphical mixer application for EMU 1010 based cards like the E-MU 1212m, E-Mu 1616m and E-MU 1820 models. I am releasing the first source package of EMutrix, version 0.1 at http://emutrix.googlecode.com It is mostly functional, allowing arbitrary routing between the card's multiple inputs, outputs and ALSA, setting clock rate and pads. More features to come in future versions. Try it out if you have an E-Mu card! Any comments welcome. Greetings, Camilo

jMax Phoenix beta 0.6 is out

by Maurizio De Cecco

After many month of development, we are proud to announce the version 0.6 beta of jMax Phoenix. The major highlights for this version are: - A first version of the puredata source compatibility kit, including the build system and a full example of recompiled object library. - A large set of usability bug fixed; all the bugs preventing a smooth work flow have been fixed. - Error handling improvements: most of the bugs and configuration errors now results in error messages, and not unexplained freezes. - A set of examples and tutorials has been recovered from old ISPW archives; they are not updated to include all the major jMax functionalities, but it is better than nothing. Full release notes are available in the release notes section of the projet site. This release has been tested on Ubuntu and Ubuntu Studio 10.04, Debian 5, Fedora 13 and Mandriva Spring 2010; check the installation instruction on the projet site for specific caveats for Debian and Fedora. The Puredata compatibility sub-project has been *very* time consuming; in order to better manage my scarce time resources, we need some user feedback (and possibly help) to be able to evaluate the actual interest of pursuing this development direction. For more information and download and installation instructions go to http://www.jmax-phoenix.org/. For contacting the project team: contact(a)jmax-phoenix.org The jMax Phoenix team

Re: [LAD] Best way to insert DSP module in audio chain in Linux

by Kim Therkelsen

Thank you very much for your advice everyone. As mentioned I have already made the LADSPA plugin and tested it with PulseAudio, so I will take a look at the PulseAudio LADSPA plugin module loader and see if I can add the functionality I need (multichannel audio and detection of when headphones are plugged in). Then I will see how it goes from there. /Kim
