Soundbox project and Alternative party

I've been building a digital instrument that has been inspired by the Luna Mod which was presented in the Make magazine some while ago. It is a two-voice software synthesizer implemented on an Atmel ATmega88, an eight-bit microcontroller. It plays a short loop of sounds which are programmable by selecting suitable pitch and amount of arpeggio and pressing a programming button.

I will present this device for the first time at Alternative party 2011 which starts in less than 24 hours. It's a festival for many sorts of digital art, especially demos (as in demoscene, not short versions of games) and there have been many electronics enthusiasts – such as KOELSE - Association of Experimental Electronics and Helsinki Hacklab – in the last years. I'm confident this project will fit right in there.

I'll write more about this project soon, at least something about the electronics and software design in this device and about how the control panel was made.

The source files and an electronics design drawing made in Fritzing are available at a GitHub repository.
