The Zeroscope from Intellijel is a two channel oscilloscope with Tuner and frequency meter for Eurorack housings with 1U series. With this smart oscilloscope every modularist can feel like a laboratory technician or scientist, because it graphically displays all kinds of signals in the Eurorack at lightning speed and also offers the possibility of, for example, the frequency of an oscillator or LFOs, the result is displayed either in Hertz or as a note name (E3, C2, d#5...). Very practical and with a touch of retro science fiction look, it even comes for free.
