States 3P4T CV source

Building on the State SPDT cv source, this is a 3P4T version of the same concept - a 3-channel eurorack preset module. The three outputs send out CV (0-9V) from the row of trimmer pots selected by the rotary switch. The transition between voltages can be slewed per channel with a range from instant transition to a couple of minutes.

The idea of this module is to be sort of a preset bank for performing with modular synth. The three channels could for instance be set to control envelope decay, filter cutoff and modulation level of a voice in a patch and thus serve as a macro controller for dynamics in a performance.

The pcb and frontpanel were designed in EasyEDA and manufactured by JLCPCB.
