The Erica Synths Pico Drum2 (Black) is a versatile Drum Module for Eurorack Synthesizers. The 8x different Algorithms or Sounds are a good foundation, each of which can be edited with 2x Parameters and the internal Decay Envelope. The first 2x Parameters can be Modulated with a Control Voltage, and the 8x Sounds can also be called up with CV. Since the Algorithms are over-writable, you can easily save your 8x current Settings and recall them the next time you use them.
