I love my TX802. The TX802 is actually 8 2 note polyphonic tone generators that can be combined as 1 16 note TG, 2 8 note TG's or any other combination.
It is not 2 DX7's. It would have to be 32 note polyphonic. It's more like 1 DX7 that can be divided up into parts which could be layered, assigned note ranges and MIDI channels.
TX216..........2 16 note TG's
TX816..........8 16 note TG's
TX802..........8 2 note TG's
I think this makes sense.
