CV and CLK in

Implement 4 (?) CV in and 1 clock in. With 4 knobs a single MCP3008 ADC might be enough but in the end might need two of them.
Both hardware and software implementation required.

CV and some gates can exceed 10V up to 12V (?), so the MCP3008 is not enough as it has a max input of 7.6V. We have to use another ADC or decrease the voltage though some additional circuits

Yess I think we should first try out adding a simple op amp circuit to map
the eurorack range to MCP range.

Sounds good. We can check also ADCs that take higher voltages so we can avoid making extra circuit
