Five Dimensions of Touch

Strike (velocity), Press (polyphonic aftertouch), Glide (pitch bend along key), Slide (vertical axis parameter), Lift (release velocity). Combined with MPE-compatible software, these enable violin-like vibrato, saxophone-like breath control, and guitar-like bends from a keyboard format.

MPE: MIDI Polyphonic Expression

MPE treats each note as an independent MIDI channel, enabling per-note expression data. Compatible software includes Bitwig Studio, Ableton Live 11+, Logic Pro, and many modern synths.

Learning Curve

The Seaboard requires real adaptation. Most players need two to four weeks to feel confident. The reward is a genuinely new way of making music.

Who Is It For?

Curious, experimental producers who want to explore new ways of interacting with sound. Particularly for sound designers, ambient music producers, and anyone who finds conventional keyboards creatively limiting.
