A four voice wavetable synth/sequencer/visualiser that you can build with only two potentiometers, a few leds, resistors and caps.
Its basically a pocket nightclub -
Its a lot more than that, but in my non musician hands it will only ever sound so good.
So if you would like to contribute to the project, please get the source code and build something cool

Excellent idea! 8) Yet, for the real night club experience you need visuals as well. 
I'd say at least a few RGB LEDs controlled by a color organ circuit, either directly using the audio signal generated by the Arduino or more conventionally using microphones to pick-up the sound.
Hi,
I have lots of ideas to develop this, for example, a rotary encoder as a slip mat for scratching - or just for fun a small mirror ball if I can find one.
Why not build one and see what you come up with for yours.

Just finished building one... What an amazing little device for so few components.
Have you finished the refactored code yet?
Hi,
It is great for something so simple, once the code has been tidied up a bit there would be a good case for including it in the Arduino samples it knocks the socks off blinking an LED or playing a tune with the tone library and is a pretty simple circuit to build with huge potential for people to build on.
If your using the original illutron code, PM me your email address and I will send you the IllutronB code I used for the video, it allows you to change the pitch of the one channel and control the speed of the sequence, it also drives the four LEDs and is based on the first cut at refactoring and optimizing the library.
I need to have another run through the library there are still one or two floating point calculations that I want to replace with integer maths but these will be minor changes, the basic structure and interface to the code is likely to stay more or less the same.
I have sent the library to quite a few people now so hope to see some cool projects posted and if anyone can make some demo sequences or drum tracks I am happy to include them in the examples with library.

Hi,
As I get asked for this and some of the other RCArduino projects on a daily basis, I have uploaded the zipped project folders to google drive.
