??? I think you misunderstood what I meant. I am not suggesting to build a polyphonic modular.

I meant you can use paraphonic / polyphonic synth as an ambient pad (with CV in / VCV Rack etc.). Then, use Eurorack in parallel to create a melody/timbral variations based on the harmony of the ambient pad. Especially, nowadays some synths like P6/OB6 are compatible w/ MIDI MPE, you can modulate the parameters of each voice instead of all voices. It also depends how you are trained too. For me, I prefer to play with a keyboard, instead of using a quantizer/chord generator. Eurorack to me is more about exploring timbre instead of harmony.
