Rotation
Rotation is useful for many effect parameters as it can be held in place and the effect parameter can be
turned on and off easily. Rotation is always clockwise or anti-clockwise. Holding the sensor in different
orientations does make some difference and so it is best to start and finish in the same orientation.
The sensitivity control and bi-directional switch have no effect on rotation.
Choose a distortion effect parameter
Set min depth to minimum (fully anti-clockwise)
Set the max depth to maximum (fully clockwise)
Press the on/off/calibration switch so that the ON LED lights.
Place the sensor on the headstock or body of a guitar
Calibrate horizontal to the ground, moving left to right over a medium angle (45 degrees)
The sensor can now be moved backward and forward and the distortion effect will increase as it is
turned. Hold the sensor at the point where you are happy with the effect level.
When ready, swing back in the other direction to lower or stop the effect
Adjust the maximum depth control to limit the level of distortion, and/or the minimum depth
control to keep the distortion from disappearing completely.
Velocity
Velocity is a little like rotation, but rather than the effect parameter being held, when the sensor stops, the
modulation will return to zero and stop.
There is no angle calibration required for velocity, but the sensitivity control may need to be adjusted.
Move the sensor and note how quickly it needs to be moved to reach full modulation level (127).
The sensitivity control changes how fast the sensor needs to be moved to reach full modulation
level. You will need some trial and error testing, but start with the sensitivity control at 75 (3/4
clockwise). If you don’t get the modulation level needed, either move the sensor faster or increase
the sensitivity control.
Choose a vibrato or tremolo effect parameter
Set the bidirectional switch ON
Press the on/off/calibration switch so that the ON LED lights.
Place the sensor on the headstock or body of a guitar
The sensor can now be moved backwards and forwards and the effect will be heard to modulate and
then cease when the sensor ceases
Try it with the bidirectional switch OFF and the modulation will only occur in one direction.
