I've got the basic one, but that doesnt tell me the nuts and bolts of the synth engines, which is what i want to know about.

I've owned many of the FM synths since the DX7 (DX 7 11, 9, 21, 100, SY 77, TG 33, TX 7, 802, FS1R, DS-8)

So well familiar with FM synthesis and can make heads from toes just by reading.

But I need to sell other gear to buy it and having the full manual will allow me to do this asap.

I know if I have to wait to long I'll loose interest so please hurry up Yamaha.
