zynaddsubfx - http://zynaddsubfx.sourceforge.net/

Is an amazing multichannel, realtime 'analogue' synthesiser with fx using an FLTK gui. Does CXX00 range, overclocked, have enuff processing umph to run this? I need to find out!

seq24 - http://www.filter24.org/seq24/

fantastic, slimline GTK MIDI sequencer

specimen - http://gazuga.net/

virtual sampler, GTK based

audacity - http://audacity.sourceforge.net/

Great wave editor

So, the idea is we get these ported to pdaXrom for a neat litle portable music making machine! I presume I'd be able to even get a USB MIDI adapter working with my C3000 (when the pdaXrom port gets finished) for the icing on the cake? I'm pretty sure thought that seq24 and specimen need ALSA, is this a problem?

I'm new to the world of the Zaurus and cross-compilng, so I've got a few questions:

Can I run pdaXrom binaries under X/QT (under Cacko)?

How big of a performance hit is there when running stuff under X/QT as compared to pdaXrom?

Could I get a Debian ARM binaries for these and run them under X/QT or pdaXrom?

iWMMX - Is it only programs that were coded to use MMX that can make use of this or can any multimedia prog be compiled with iwmmx and see performance gains?

Thanks for your help!

UPDATE

Cor- I can't believe its almost 5 years since I asked this question!

I now have zubuntu installed on my Z and milkytracker, which is in the ubuntu repos, works great as does USB MIDI via ALSA and I've even got specimen to run on top of JACK. I had to build specimen from source as the package in the armel jaunty repos didn't work at all for me but the specimen interface is very usable @ 640x480 without modification and I've got our KORG nanopad bus-powered USB MIDI drum pad/controller working great with it

BUT

I've so far been unable to get a clean sound out of specimen, despite much messing with alsamixer settings and jackd (-n , -p, -r) switches. If I play my wavs on the zaurus via moc, mpg123, vlc etc. they sound fine, but I always get a bit of crackle when they get played back via specimen/JACK. The kernel I'm using at the mo doesn't support CPU scaling so maybe if I was running at 600+ Mhz it may become usable?

Once we get JACK/specimen working OK, seq24 should be within reach. These apps combined with sweep and the Z becomes and nice pocket studio!
