Lightbulb Csound - Debian.

Csound. plugins maybe too. speakers. microphones. this I know.
There are a few hello world tracks that I will attempt to run.

OLD MESSAGE:
Spoiler:
I prefixed this K3 because I am going to to test it on there.

IF it runs on that it will run on the others I figured.

building it now, for those of you with a life you probably haven't heard of this app but if realising sounds through mathematical constructs and lo level opcodes is your thing then Csound is the daddy.

Will report what falls out of it.

Also the gui tools are of interest now so they will be given a shot.

Fingers crossed.



Short answer. it works - barely on a 3 - and not too bad on a 5

Going to run a few procedural works through csound on the kindle now. I will attach the outputs here Kindle Studio - World First?

sigh. Gui on "Backburner" then.

perhaps I will hack together the sound support in the interim.

perhaps I will DIY a gui too

Wish list for audio editing. (bare minimum or better)

Feel free to append.

Required support: wmctrl, (debian: Xephyr) an editor (nano), file, an HTML browser? (mozilla is wanted), X, ALSA, ...

Extra bits: alsa-utils , xsox a sound file converter (libsoundfile frontend?) , LMMS(thanks Qlob) a different one... Any ideas? Ardour is a no.

Core: Csound, CSound5Gui, Cecilia, Audacity.

TBC.

Good call. Yeah I too honestly doubt it can.

However this wish list could also form a native port list given the right circumstances.

and in the interim I will look at performance on the 5.

I got Audacity running on the K3 (audio was trashed though, would need love)

Thanks for the feedback. Greatly appreciated.

LMMS is a no for now from armel. as is ams. any other ideas?

wmctrl file alsa-utils nano alsaplayer-gtk audacity alsaplayer-common autotalent rev-plugins wah-plugins csladspa wah-plugins tap-plugins vco-plugins cecilia csound htop csound-doc fonts-liberation qutecsound graphviz libcgraph5 libgvpr1 ttf-liberation

nice to have (but no midi or jack yet):
qjackctl bristol bristol-data composite composite-data

Not helpful: buzztard buzztard-data calf-plugins aqualung

needs root to run currently: alsaplayer-gtk aqualung audacity

TODO: Get jack running. pftt. maybe....

So anyway I crashed on to see if the 5 could be actually used.

It was slow but a servicable on-the-go toolset is beginning to emerge.

Still looking for a better way to manage the overall but in the end audacity may suffice properly configured with some layout love.

Will do some Landscape screenies too. but playback was solid and processing reminded me of 10 years ago, which was fine, I put up with it then

hmm. will have to use http://www.linuxcommand.org/man_pages/alsactl1.html
again like I did on the 3 and see about implementing some midi then.

I may have a friend who can help with that. Also need to get Jack up. He can probably help with that too, so let's just say WIP.

Installed and cruised likely winners going forward for the virtual keys as and when we breathe some life into the sound support. which was surprisingly solid. Kudos Lab126.


EDIT: Erk. That config is a bit stern. ho hum. I'll look into dual configs streaming or something.

Is there any way you could compile that stuff to use the K5's hardware floating point? (It has two (2!) vfp3 co-processors + the NEON SMID).

i realize that might be a challenge, since the system libraries are not compiled hardware float.

Like a hard float cradle for the debian.?

Or maybe just compile a hard float version of the kernel?

I'm open to ideas for better performance and I don't think anyone will complain if I bother to make one. : )

Okay realtime is out with a big interface. Overhead is a killer.

the 3 actually does better from the command line. I will try that next for realtime on the 5. It was a struggle to get anything to render also via qutecsound but meh it was fun.

EDIT: Ooh and a last minute juicy death to keep things fresh. nice : )
