Mutable Music Things Ears

Ears, a collaboration from Mutable Instruments and Music Thing Modular, is a novel way to get tactile noise and gate outputs into your Eurorack system. It has a contact microphone attached to the panel, which can be scraped, tapped, rubbed, hit, or bumped for a wide variety of output noises and signals. It also has an external input, with 40dB of gain, able to bring anything up to modular level. Following the external input or the noises generated from touching it is an envelope follower, which outputs CV based on the volume of the signal. Pairs great with resonators like Rings and Elements!

Ears being used in tandem with other Mutable Instruments modules Rings, Elements, and Frames to create some clangy bell-style sounds, which are then altered via Elements's resonator section.
