Hi Torsig,

Yes, you've got it right, basically.

TX7 (one DX7): correct

TX81Z (4 operators): wouldn't bother with this one.

TX802 (two DX7s, multitimbral): has newer DAC than the older DX/TX synths, and is a 2 space rackmount unit.

TX216 (no idea): like 2 DX/TX-7s, and is a 3 or 4 space rackmount unit. This is like the TX-816, but with only 2 TF-1's placed in the unit. It can be expanded if you find additional cards (rare).

TX816 (eight DX7s): contains all 8 TF-1 cards already. These units can be had for a song these days ($200-$500 used). Disadvantage: each TF-1 has a separate XLR output, so you'll probably need a separate mini-mixer. This one also has the older DAC's, unlike the 802. The 816 is overkill, unless you're really into FM synths (I used to have one).

The 802 (used price is about $250) or maybe TX-7 is the best choice if you just want a bit of FM in the rack.

Hope this helps,

Christopher
