midi light show

[Alkex]

Hi,

I have a few small gigs lined up in the future and would like to add some colour to our performance by sequencing rgb light fades to the tracks (differant colours to diff moods etc).

I have allready used a binary system using high powered relays attached to douts that is a good start for flashing bright lights etc,

but I would like to go one step further and "animate" colour changes be applying variable voltages to three 12v ultra bright led clusters(RGB)

I thought the aout_lc module would be a good basis for the project, but I dont need negative volts, so can I bypass the -12v supply?

I would rather avoid having to build two modules just for one extra output, would it be possible say to reduce the resolutions and use a quad amp, and if so which amp would you recommend? oh and a stupid question: would even be possible to multiplex the channels to differant leds, maybe the eye would be to slow to notice the flicker...

If you guys can pinpoint me on the hardware side of getting three 0v to 12v channels out of the box, I can then write a little program with coulour change scenarios to choose from when not receiving midi thus making it a nice decoration to have in the house when not on stage  :)

Thanks in advance for any ideas towards this project

best regards

Alex
