mikrosonic has launched version 2.0 of RD4 – Groovebox, a music creation app for Android devices that combines two virtual analog synthesizers, a beat section with drum kits from classic drum machines and free assignable audio effects.

The new version comes with a new synth called Analog modeled after legendary monophonic synths of the ’70s. The new synth has a piano roll and the user can also record notes in real-time with the virtual keyboard. The app supports low audio latency on specific Android devices.

The app has now a 4 channel mixer and the user can choose individually for each channel between the Analog, the Bassline and the drum machine.
