Novation (with its recently rebranded sub-brand Ampify) has released new iOS app (iPhone and iPad) – Groovebox. It is a sample based drum machine and two synths (bass synth and poly synth). After playing for some time with the app I found it pretty nice. And it really reminds me first versions of Korg Gadget – few easy to control devices with nice sequencer.
Right from the first version Groovebox supports IAA, Audiobus, Ableton Link and Ableton Export).
The app is free with IAPs to unlock all the parameters of synths and drum machine.
