Groovebox Free (IAPs) Made for iPhone, iPad

This free entry–level app from Novation is great for fledgling recording artists, as it offers a relatively easy–to–use interface and hundreds of patterns and sounds for putting down your next beat. The app has two Novation–designed synthesizers, a drum machine, a mixer, a note sequencer, and key and scale modes, with plenty more samples available as in–app purchases if you should ever need them.
