RD4 - Groovebox: Make music with synthesizers, drum machines and effects!

Turn your phone or tablet into a musical instrument! RD4 - Groovebox is a music making app with virtual analog synthesizers, drum machines and effects.

Compose and arrange your music in real-time. Choose instruments individually for the 4 channels. Record live or set notes with the dedicated sequencer or piano roll of each instrument.

"This is no desktop app crammed onto a touchscreen. It seems the interface has been designed around your fingertips." Peter Kirn from CDM (createdigitalmusic.com)

This multi-touch enabled app makes it simple to invent unique loops and musical phrases. Manipulate the sound of the synthesizers by tweaking the oscillators, resonant filters and audio envelopes. Add audio effects like reverb, distortion, phaser, filter and delay to your sounds.

Appropriate both for experienced musicians and beginners.

Loops you've created and exported with RD4 can also be automatically integrated into mikrosonic's audio mixer app SPC - Music Sketchpad.
