This is a flexible 1-4 sequential switcher with S&H, T&H and ASR modes. The maker presents it as a sequencer aid, but its much more than that, and will distribute a fixed or moving CV + gate to the 4 outs in a number of ways that can be changed in flight. The ASR opens the door to chaotic processes, and outputs the shifting values to all outputs at the same time. It's a lot of fun.
