Play instruments on your iPhone, on screen or with a MIDI keyboard
Musaic has nine instrument families with 49 sounds: piano, bass, drums, synth, strings, guitar, harmonica, brass and mallets. You play them on the screen or on a USB or Bluetooth MIDI keyboard, and every recording lands on a new layer while the song plays back. The keyboard can show only the notes of your song's key, so every note fits. The instruments are free.

You need: Nothing extra. A MIDI keyboard is optional; USB and Bluetooth MIDI both work.
