Toppobrillo Cluster - Black ornamanet Through-zero linear frequency modulation (FM)Cluster is Toppobrillo's take on the workflow of the versatile Buchla 200 series control voltage processor model 257 with some marked improvements and options. Missing is the cool equation, but they kept some arrows and replaced the variables with LEDs :) They've also also added a voltage controlled polarizer (4 quadrant multiplier), an extra processing mixing channel and routing options that make it an extremely flexible and more compact tool for the
