In principle the MC-202 can be controlled via MCV4 or MCV24. But the MC-202 has one special quality: the external CV input is not connected to the VCO directly and the external gate input is not connected to the ADSR directly. Rather both CV and gate are processed by the MC-202 microcontroller before they reach the VCO and ADSR resp.

This causes delays for both CV and gate, and in addition a quantization for the CV. The external interface (e.g. MCV4 or MCV24) is not the reason for these peculiarities but the signal processing of the MC-202.
