Really great box with a lot of fresh and inspiring sounds as well as plenty of ressources to create new ones. The problem is the documentation: is someone knows how to load Formant sequences in its memory? Also looking for a PC editor/librarian.

what kind of music is it best suited for?

The FS1R is good for any kind of music except
GM! Imagine a DX7 with 16 operators.
You can get thoses thin digital sounds as well as really fat bass and leads. The pads
are very interesting too. I have a lot of synths and I'm used to programation but the FS1R is in its own class: THAT'S A SYNTH, and
its editing is NOT simple.
