Korg Grandstage specs
The Grandstage is Korg's stage piano, combining the SGX-2 acoustic piano engine with EP-1 electric pianos, the CX-3 and VOX organ engines and HD-1 PCM in one instrument. It uses the same RH3 hammer action as Korg's upper-end home pianos and loads about 19 GB of preloaded PCM (roughly 32 GB linear). The panel is deliberately direct - 500 sounds, 64 favourites, a Dynamics knob, Smooth Sound Transition and a hardware three-band EQ.
