Mutable Instruments Yarns in Poly

Hi All,
On the Yarns, there is the 1,2,4 Mono and Poly but what about 3P?
I assume you use 4P for Polyphonic but what if you are controlling only
3 Oscilators? I did some testing in Poly but not fully…i wonder how you
can achieve only 3 with the 4 Setting or any other solutions?..

Thanks

There is a setting called 3+ with 3 voices of polyphony and 1 extra independent mono voice.

Thank You Sir!
