[PD] Pd & a lighting console

[Alexandre Quessy]

Hi,
This all sounds good. Really interesting !

I find that Marc's way to do it with dimmer boards must be the most 
efficient one. But it would take quite a few days to implement. (I 
don't want to cross the street and borrow your dusty stuff : it's for a 
portfolio...) I wish I could use a micro-controller yet, but I am still 
not a assembly programmer !

There is http://semitone.sourceforge.net/diamond/ that could be quite 
interesting in this spirit. A perl script in the semitone software 
utilities at 
http://sourceforge.net/project/showfiles.php?group_id=80137 could allow 
Pd to send messages from the shell. Perhaps we could even pipe the Pd 
sound output to [g]mplayer and then to their perl script dimplayer. 
Would you think it could work ?

As I am currently "only" running on OS X, the USB to DMX solution would 
be ok, even though I would need to hack my kernel. Not too bad. The 
dmxusb external looks all right. I would just need this Open DMX USB 
device. (100$USD)

I think that the quickest way to realize this would be to use a midi 
out. Then, I just need a midi-compatible lighting console. It would 
also be quick, as in CPU-time. This (a compatible console) must be 
possible to find somewhere around. To get things simple, I even thought 
about displaying colors with a simple projector, but then, there 
wouldn't be much fun left...
