Notes:

¹ Keyboard Mechanisms: FW = fully-weighted hammer-action / SW = semi-weighted / SY = synth action.

² GD = German D, JC7 = Japanese C7, TS = Triple Strike.

³ KSR = “Kurzweil String Resonance”.

* These pianos are an optimized version of the Forte® Grand pianos, derived from the same quality content but using less samples.

** Cannot load K2 Series KB3 or Triple Mode Programs. Edited ROM sample headers as well as some DSP algorithms and tools cannot be converted. Please see owner’s manuals for details.

*** Half-damper pedal sold separately.
