Summary: The Motif range ups its game with 128MB of pre‑installed sample RAM and double the sample ROM of previous models, then takes a quantum leap with the option to add 2GB of Flash RAM for permanent onboard sample storage. Even if you haven't been drawn to the Motif before, this feature alone could change your mind. Existing Motif owners will be sorely, sorely tempted to trade up to the XF.
Pros: Option for 2GB of Flash RAM, currently the largest capacity available in a keyboard., 128MB sample RAM pre‑installed., More than double the wave ROM of the Motif XS., 128 more user Voices and Performances than the XS.
Cons: The shortened keys and uncomfortably feather‑light action of the FSX synth‑style keyboard risk emasculating a professional instrument such as this.
