Real FM sounds for the Genos2 Tone Generator can probably only be produced by Yamaha at the moment.

True that, Chris.
YEM 2.10 has UVF (XML) tags for FM voices. No secret, the tags correspond to Montage/MODX FM-X voice parameters.
The problem, at the moment, is how the tags are used in a UVF voice structure. All we need is one example of an FM UVF voice file and we should be able to fill in the blanks, so to speak.
However, that leaves the larger issue of actually creating and editing an FM voice in UVF. There are 25 per-op parameters -- well over 200 individual voice parameters in an 8-op FM voice. Creating an FM voice is difficult enough, but doing it in XML text?
Probably the best path moving forward is to edit on Montage/MODX, export, then translate the exported representation into UVF.
That's a lot of work vs. the number of people who will actually create new FM voices for Genos2. Yeah, there are a lot of empty hands out wanting FM voices, but actually creating them...
All the best -- pj
