The Mother 32 is mono so it only needs a TS to TS 1/4 cable. So what your saying is in order to get each oscillator from the modular to a an external analog mixer or audio interface each on its own channel is you will need an output module in the end signal chain for each oscillator? Mother 32 to an output module then to channel 1 on external analog mixer. 303 Osc to filter, amp, e.g., lfo, effects then another output module to channel 2 on mixer. Wiard Osc to filter, amp, e.g. , lfo, effects then another output module to channel 3 on mixer? And so on so on?
