inverse
127 becomes 0 and 0 becomes 127. This way you may inverse the curse of a sensor. With an
expression pedal, for example, you’ll be able to inverse its curse.
status
on/off
The status field indicates whether the signal on an analogue input should be converted into a digi-
tal message or not. This field may be set to ON or OFF. If the field is set to OFF, the input is said to
be inactive and no message relating to that input will be generated, even if a signal does physically
enter the device. If the field is switched back to ON, the input is active and its associated message
will be sent each time the signal connected to that input varies in level.
Note:The smaller the number of active inputs is, the less data will be transmitted avoiding proces-
sor computation.

Want to stay in the 7-bit MIDI world...
Those two parameters (digital zoom and offset)
specify how the real range of an analogue input can
be mapped on a 7-bit MIDI value. As a matter of fact,
a sensor does not necessarily have a range equal
to the reference voltage of the Analogue to Digital
Converter. A custom scaled zoom has been imple-
mented on the digital value to take advantage of
the 12-bit resolution of the A/D converter. Then, the
user can select the sensor’s range within the 12 bits
dynamic by specifying a window size and an offset.
The selected range can then be converted into 7 bits
MIDI data without greatly increasing the quantification
step, as shown in the illustration.
The digital zoom & offset parameters may be very
useful to modulate a filter on a certain part of the
amplitude.
