1) Werstatt-01 does not have midi input. So we need to use KB output from Moog Mother 32 , which is connected to 'VCO EXP FM IN' of Werkstatt-01. (You might need to calibrate the pitch first to get accurate notes.)
2) CV out from Doepfer Dark Link USB/MIDI to CV/Gate interface to 'VCA CV IN' as well as 'VCF CV IN' (You need a stackcable patch cable). This connection can give more expressive and dynamic sound control, compared to single CV connection to 'VCF CV IN'.
