[linux-audio-dev] Project ideas?

by michael tewner

I posted here a bit ago about implementing gibson's MaGiC protocol on linux as a final university project. Anyway, I was looking for other possibilities. The project can be fun and all, but has to have some acedemic value (being able to "publish" is a big plus). Perhaps working on that Juno9 VST? I don't have *too* much programming experience, but I learn fast. Any ideas for a interesting program is greatly appreciated. ...Perhaps, it'll make a good list to post online for people that wanna help out linux audio support but don't know what's needed/wanted. Thanks y'all -mike

One of my pet peeves. Knobs make absolutely no sense in a GUI. There is no easy (or standard) way to control them. Note that there are no knobs in JAMin. The parametric controls aren't even knobs.

Basically, you create a base file in povray, start gimp-perl server and then run the Perl script to create incremental images and convert them to whatever format you need. Some examples are here: http://members.optusnet.com.au/~adamjking/images/knobs/knobs.htm The scripting is a quick and dirty hack, but it work for me. Cheers, Adam

Sorry, you are correct. In JAMin it's center click.

In addition to graphics designer, programmer, tech supporter and occasional gofer. The audio industry is actually quite tiny. I doubt that ANY audio software company has a dedicated usability engineer. I've never seen such a position posted. The industry probably needs a usability standard but I would be very surprised if anybody actually followed the standard we produce. Everybody, by definition, is a usability expert in their own usage habits. But I'm willing to discuss it if anybody wants to bounce ideas around on- or off-list -Ben Loftis

No, I didn't dream it, I wrote it. I may have missed a slider or two but I think I got most of them. Of course I am talking about the latest CVS not 0.8.0.

by vanDongen/Gilcher

IMHO this is much bigger problem in UI design. In ardour it is shift-click in JAMin it is right click, in Rosegarden it is double-click. That the sliders all look different is much less confusing than that the behaviour is all different. Maybe some kind of audio app interface design proposal is in order: linux audio interface design - basic application control keys: LAID BACK Gerard On Tue, 2004-06-08 at 14:22, Chris Cannam wrote: > On Tuesday 08 Jun 2004 7:46 pm, eviltwin69(a)cableone.net wrote: > > Right click on any slider in JAMin and it immediately goes to > > the default position, whether center or zero. > > Ah, now I looked for that feature but didn't find it.
