@BK-Sannerud Yes it's a pretty simple setup compared to other FM synths, but it gives you the ability to FM a multisample set, which is nice.

If you want to go crazy with multiple chained modulators etc, you need to look into scriptnode.

@hisefilo I checked it out, it definitely allows for more detailed shaping, although I have to do all the shaping in the attack phase. Still seems that if I release the key before the note is fully built-up, it stops right there and ruins the effect. I can filter out all note-off events, but then I wonder how to add a choke key. I also worry about the CPU hit, if the note continues playing silently - I shall have to experiment more.

Tl;DR that seems like a step in the right direction, thank you!
