Native Instruments have announced 2 new additions to the Maschine line of software/hardware drum machines. First up is Maschine Micro, which offers the same software and sample library as the original Maschine, but includes a smaller, more portable controller and a lower price ($399).
Additionally, they've released their first iPhone/iPad app called iMaschine. iMaschine is focused on mobile beat-making, allowing you to program rhythms, add samples via the phone's mic, and export your projects to the full Maschine software to finish up. iMaschine features a small sample library (100MB) and goes for $4.99.
