MultitrackStudio for iPad app for iPhone and iPad

MultitrackStudio turns your iPad into a digital multitrack music recording studio. You can record, edit and mix audio and MIDI tracks. Both "one man band" recording, adding tracks one at a time, and live multitrack recording are supported.

Both audio and MIDI tracks can be edited. MIDI editing features include pianoroll, drum, score and pattern editors. Tempo and time signature can change throughout the song.

MultitrackStudio for iPad comes with many high quality audio effects including a guitar amp simulator. MIDI instruments include GM-compatible MultitrackStudio Instruments, SoundFont Player and Matrix Sampler. External (hardware) synths can be used as well.

AUv3 audio effects, instruments and MIDI effects are supported, so 3rd party apps can integrate into MultitrackStudio.

The straightforward user-interface has been designed with tape-based recording in mind. Its easy to use yet powerful.
