I second the Volcas -- I bought a Volca Modular[0] this month and am enjoying it greatly, though if "music" is what you're after you probably want the Volca Keys[1] which is cheaper and less weird and has MIDI input. I also recommend the Keystep 37[2] from Arturia as a MIDI controller -- super interesting sequencer and arpeggiator plus decent quality mini-keyboard and some assignable knobs -- but must point out that it's only "bus powered" on a computer, your iPad or smartphone probably won't power it without an additional power bank.
