ADDAC303 Muscle Sensing is a module that senses muscle tension with electrodes and produces envelopes and a gate signal. It's perfect as a non-traditional interface for your modular. The envelope and inverted envelope have controls for gain and offset, allowing you to dial in the voltage range. A comparator is included to generate gate signals when the interface detects a voltage over the threshold level set by the control. There are three modes of slewing available. The smoothness switch selects between no slew, soft (which is a short slewing), and hard (which is a more pronounced slewing between voltages).

Get your flex on and control your modular with your rippling biceps. Or, attach it to a bass player or drummer to get a new layer of interaction between band members and modular.
