The SidTracker 64 is a complete chiptune production package for iPad. It features a new emulation of the SID soundchip found in the commodore 64, a sequencer, instrument editor including advanced wavetable editing and MIDI input with assignable controls for any control surface. Here's a list of features from the developer's website:

Tracker & Live Looping
Create chiptune music with the same creative tools as back in the days, but with the benefit of a modern user interface. Record live or step edit. Loop and create songs on the fly. Unlimited possibilites.

Midi & Connectivity
Play live and record using your midi keyboard and edit the sounds with assignable controls for any control surface. Instant gratification. Audiobus 2 and in-app audio supported for full integration with other iPad app

Synthesis
Many tricks were invented to fully exploit the possibilities of the SID ship, which has made it quite a bit different compared to what you might be used to. From basic subtractive analog synthesis to wavetables and filter tables controllable down to 1/240th of a second for micro sculpting that you probably haven't experienced before.

SID power
No samples, no bullshit. This is the original SID-chip replicated to perfection. You can even export to play back on a real Commodore 64, should you feel the need for it. Do you make music for C64 demos? This works for you.
