• Function 1: Pitch Bend
Wave your hand in front of the left sensor. The display shows a cute spinny-thing to
represent Pitch Bend Up and Down. As you move your hand, the display spins and the
pitch bends. When you lock into the fully-bent pitch, either up or down, this symbol
appears: “
0.
” Remove your hand to snap back to the “Neutral”, or “No Bend” position,
indicated with “
f
”.
Turn the DATA FAR knob to display numbers
0 - 12
. With a Macchiato Mini Synth, this sets
the number of semitones the pitch will change at maximum bend. On other devices, this
knob will have no effect or an unpredictable effect. Set to
0
to disable Pitch Bend.
Turn the DATA NEAR knob to display numbers
0 - 127
. This changes the size of the
Neutral Zone in the air, separating the Bend Up and Bend Down zones. On startup, the
zone was set to 127: you will find a large piece of air where the pitch remains unaffected.
Change it to zero and the Neutral Zone diminishes.
