ROLI Seaboard GRAND

The standard ROLI Seaboard GRAND features 32 fully weighted keys laid out across a unique, undulating silicone surface. While it spans two and a half octaves, the continuous nature of the keywaves allows for much more complex phrasing than a traditional 32-key keyboard. The larger GRAND Stage model expands this to an 88-key equivalent.

The undulating, keywave design allows the soft silicone material to flex in multiple directions, giving the player extensive expressive control over pitch and modulation. By pressing deeper into the key, sliding it left or right, or lifting off slowly, musicians can shape the sound continuously. It essentially removes the barrier between the player and the synthesizer's parameters.

It is generally not recommended for beginners because the squishy, highly sensitive surface requires a completely different muscle memory compared to a traditional piano. Beginners often struggle with unintended pitch bends or volume spikes due to the intense pressure sensitivity. It is much better suited for advanced producers and synthesists looking for nuanced performance capabilities.

Because of the advanced sensors and processing required for multidimensional polyphonic expression (MPE), the keyboard requires a dedicated DC power adapter to function. It cannot be powered solely via the USB connection to a computer like many smaller, basic MIDI controllers. This ensures the sensors receive consistent voltage for accurate tracking.
