UPDATE (12/12/2016)
PEOPLE, PLEASE STOP BUYING ADDRESSABLE LEDS FROM RANDOM EBAY SELLERS, THERE ARE SOME BAD BOYS SELLING COMMON ANODE RGB LEDS AS ADDRESSABLE! USE THE LINKS IN THE BOM PLEASE.

Hello Wigglers! Let me introduce to you my Prizma. It's a colorful 16 step, 2 channel note sequencer in 6HP with lots of features (variable length, playmodes, quantiser, random triggers and notes, internal clock...). "Quick start guide" is attached.
Passives and transistors are SMD (0603, SOT23, nothing to fear from). 5mm addressable LEDs can be found on eBay, aliexpress for cheap. Current consumption: 70mA +12V (with brightness cranked up it can approach 100mA), 10mA -12V.

I have a few PCBs for sale, as well as ugly, unfinished aluminium panels (there are splashes around small holes, sandpaper can work wonders).
PCB set+programmed CPU: 25€ + shipping
No more ugly panels left, new ones will arrive in the middle of june.
Fully built module: 120€ + shipping
payment via PayPal in €, e-mail me for orders (include your MW nickname)

Awesome! I've been working on a similar project!

What are the voltage outputs? 0-5v or +/-5v?

Brave man! : )
Are you using it as a random voltage generator usually?

I'm in for a PCB/Panel

Count me in for PCB/Panel

Thanks!

How are the connections for the shift-reg diodes. I see two different length lines on the PCB-screenprint - but the ones I have has 4 different length legs. So which one is VDD, GND, DataIn, DataOut? (I can probably figure the first two out...)

I'm using diffused LEDs, like these: https://chioszrobots.files.wordpress.com/2014/09/led-5mm-addressable-d iffused-chiosz-robots-8.png
