2. Keyboard Action

What keyboard action does the VPC1 use?

The VPC1 utilises the 'RM3 Grand II' keyboard action.

What are the main features of the VPC1's 'RM3 Grand II' keyboard action?

The 'RM3 Grand II' keyboard action features long keys, made entirely from wood, moisture absorbent Ivory Touch key surfaces, grade-weighted hammers, bass key counterweights, realistic 'seesaw' movement' with staggered balance pins, triple-sensor key detection, and let-off simulation.

What are the differences between the 'RM3 Grand' and 'RM3 Grand II' keyboard actions?

The 'RM3 Grand II' keyboard action is largely the same as the original 'RM3 Grand' keyboard action, however the new version features triple sensor key detection for improved repetition and responsiveness. In addition, the 'RM3 Grand II' keyboard action utilises an improved key frame construction.

Why doesn't the VPC1 use Kawai's latest 'Grand Feel' (GF) keyboard action?

The 'Grand Feel' (GF) keyboard action is currently reserved for Kawai's flagship 'Concert Artist' digital piano instruments. Moreover, it would not be possible to include the 'Grand Feel' action in the VPC1 without a considerable increase to the chassis size. Therefore, we decided to utilise an enhanced version of the MP10's 'RM3 Grand' action, which is widely considered the most realistic keyboard action available in a slab-type/portable instrument.

Are the keys really made out of wood?

Yes, all 88 black and white keys are crafted from wood.

What are the benefits of a 3-sensor keyboard action over a 2-sensor keyboard action?

The VPC1's 3-sensor action allows improved responsiveness, especially when playing the same note rapidly. Moreover, triple-sensor key detection allows the same note to be re-triggered without the sound of the previously played note being cut-off, enabling greater expressiveness and control when playing trills. Finally, the third sensor also measures the key-release velocity, allowing the software piano (or hardware tone generator) to produce notes with different tonal characteristics ranging from staccato to legato playing.

Does the VPC1 keyboard action support after-touch?

No, the VPC1 has been developed primarily as a piano controller, and to recreate the touch of an acoustic piano as closely as possible. Therefore after-touch is not supported.
