Baby8 VCP Sequencer (proto)

"here is the finished module using a proto PCB. works quite fine!
it basically is a 4017 based step sequencer providing CV out, Trigger out, and Gate out. the tricky part is the voltage control of the possible patterns: an incoming CV gets manually scaled to 0-5V (LEDs will help to do that), and then gets processed by a 8-bit ADC. the parallel out gets converted to grey code and switches the steps/stages of the sequencer on or off. they can be controlled manually too, by using the toggle switches that overwrite the ADC data...
