EditorX Sensor Input

The Sensor Input section configures a single sensor input of the digitizer.

Analog/Digital

Sensors are either analog or digital. Analog sensors output a single value that is captured by the digitizer using its analog to digital converter, after which a number of algorithms can be applied to process the sensor value and output it as a MIDI message. Digital sensors convert analog value(s) in the sensor itself and output a serial data stream using the I2C protocol that is received by the digitizer, which then can apply a number of algorithms to process the sensor values and output them as MIDI messages.

When selecting Analog, a number of conversion methods will be made available that may be applied in conjunction with processing methods. When selecting Digital, a number of sensor presets can be selected, applicable to the corresponding I-CubeX sensors.

Analog Sensors

For analog sensors the following conversion methods are available:

• Lookup table
• Absolute value
• Time duration
• Frequency
• Absolute value, then frequency

A lookup table takes the sensor value as the index for a table and then outputs the value stored at that index. This method is useful for linearizing the response curve of a sensor, such as the ReachClose, ReachFar and all Touch sensors.

The absolute value method subtracts an offset value of the sensor value and if the result is negative, changes the sign of the value so that the output is always positive.This method is useful for sensors whose value at rest, ie. when the sensor is not stimulated, is not zero but varies around a value, such as the BendMicro/Mini/Short, BioVolt and GForce3D.

The time duration method counts the milliseconds between a peak (or dip) and the following peak (or dip), if no end-peak detection is enabled. If end-peak detection is enabled, the time duration method counts the time between a peak and its end (ie. the time the value drops below the threshold set for peak detection). The range of the time duration is 1 - 16383 ms. The time duration unit can be set separately, and setting it to 1 means the time duration is output in seconds, setting it to 100 means the time duration is output in 10ths of a second. This method has many applications, such as measuring the time between taps on a Touch sensor, the time a hand was held over a ReachClose sensor or the time between two activations of a MoveOn sensor.

The frequency method operates like the time duration method but outputs a frequency instead of a time value. The frequency unit can be set separately, and setting it to 1 means the frequency is output in Hertz (Hz), setting to 60 means the frequency is output as beats per minute (BPM). This method has many applications, such as measuring the BPM of taps on a Touch sensor, or the frequency of breaking a SeeLaser-Red beam pointed at a Flash sensor.

The "absolute value, then frequency" method combines the absolute value method with the frequency method. This method is useful for capturing beats per minute (BPM) when using a BioVolt as a heartbeat sensor.
