The EFM110 Blackfly is the result of a collaboration between Electro-Faustus Noise Devices and Delptronics. It is essentially a Eurorack version of the original EFM110 Metallic Swarm Generator that provides dual springs that can be hit, flicked, and manipulated in a variety of ways to produce an array of sounds. There’s gain control over the master volume, as well as three outputs: a traditional Audio out, a Rectified out that only emits positive signals, and an Envelope that tracks along with the volume of the input signal.
