It was created to be a better way to control live musical data.

MIDI
allows a musical instrument to be physically split into two separate
parts; the synthesizer which makes the sound, and the
controller, which is what the musician "plays".
Before MIDI and similar technologies, the way an instrument made
its sound dictated what it looked like and how it was manulapted.
But now, we can now focus on, and improve the musical interface, without having to worry about acoustics.
The Sonic Palette's goals:
• Many notes or trigger points and lots of continuous control.
• Physically and mentally easy to play.
• A reasonable
size, and capable of taking abuse.
• Good feel and look, making you
want to play it.
• Allows you
to take center stage, or relax in the studio, and emote.
What the Sonic Palette provides:
• Large range in a small size (seven octaves, no extra space, no strained back).
• Freedom: sit, stand, or move while playing.
• Excellent ergonomics.
• Access to unusual chords and voicings (E17 anyone?).
• One handed reach of over five octaves.
• Expressive control.
Where did this idea come from?I
am a sax player who has always been interested in technology.
Electronics have in the past and will continue to be a powerful tool
for musical expression. Accessing the potential of current
music technology, to me is an interesting problem. Most
electronic music interfaces that include pitches have a piano
keyboard and I am not a piano player. I’ve worked
on the piano keyboard, (and taken lessons) but right away I found it to
be arbitrarily laid out, and ergonomically questionable.
Also, I found my 72 note keyboard to be a cumbersome piece of furniture
that made me to twist around away from by computer when whenever I
wanted to record. Plus, taking it out of the studio was a
chore. I began thinking about making a new interface, an
instrument that was designed from the ground up for use with current
music technology. Something like a traditional instrument, only
freed up
from acoustic restraints. Something precise,
polyphonic, logical, capable of controlling both pitch and amplitude at
the same
time, portable, comfortable, and attractive.
