Refer to the illustration and connect a potentiometer to [ain 0] as shown. The gainer I/O Gainer Module accepts up to 4 variable resistors.
Analog inputs 0 through 3 output between the range of 0 to 255.
Analog inputs are set to receive only "bang" messages. The default interval of bang message from the metro object is 100ms (10 times per second), but can be changed as needs require. The shortest message interval is 20ms (50 times per second).
NOTE: The internal sampling rate of an I/O module is about 200Hz, and returns a maximum value when requested from a PC.
