C.ARP is a totally different keyboard. Inspired by old keyboards, omnichords and tape effects, it lets you play chords and melodies as well. Its design makes everything easier for a musician who just wants to play on mobile. Just hold on a button and then swipe or tap on the right section. But if you prefer, you can access chords and notes directly on the notes grid. Pitch them, harmonize, use mod wheel and apply real-time audio effects too. Rhythm section follows you every chord you choose: pick up the style you prefer, adjust BPMs, mute other instrument, change different midi settings, change drums and play them with drum pads. Do arpeggios with different sounds and rhythmic fractions, create different sound environments with delay, reverb and rotation. The design has also been updated for iPads, so you can enjoy the buttons and sections rearranged for the screen size. Record your voice or everything else as a sample, adjust its length, reverse or loop it, make chords and melodies with it and explore other cool features on this 4th version. There's also a tutorial inside! And finally: we added bluetooth out. It means you can connect your iPhone to your Mac and send midi notes right in your preferred DAW. Just follow the guide inside. Thanks to everyone who helped me: Giacomo, Virginia, Mattia, Andrea, Giulia, Cristiano, and the others. Thanks to the masters Suriani, Frankie and Calcutta. For every question or suggestion don't hesitate to write to me
