2-OP FM broken in Plaits 1.2

[RobertPabst]

I hope someone would be able to fix, fork or address this issue. The final release of the Plaits 1.2 firmware, which was the ultimate retirement present for all that love Mutable, has a bug in the 2-OP FM mode (Green 3). It works at startup but for no clear reason it turns into a 'single VCO' after playing with it for a while and no FM modulation is heard. I own four Plaits modules (for a good reason) so I keep two of them on the old firmware because of it. My other two run 1.2 and expose the same bug. This mode is one of my favorites for obvious reasons because it's basically a complex VCO.

Thanks for reading!
