RD3 – Groovebox now available!

We released RD3 – a groovebox app for Android-powered mobile devices. It combines a 303-style virtual analog synthesizer and a drum machine with selectable drum kits from legendary drum computers. With the integrated step sequencer you can recreate the sound of early electronic dance music and program your own grooves on the go.

RD3 is available for 3,49 € in the Android Market.
A demo version of RD3 is also available in the Android Market.

A short video on youtube shows the basic operations of the app.
