Thanks for so nicely clearing this up for me.
Can you give me an example of an 8 channel A/D? I'm not entirely sure of the point you're making and I'd like to understand. Adding a second 18i20 is not adding another 8 channel A/D?
An 8 channel AD is a box that can convert 8 line signals (usually presented as 8 XLR sockets or TS jacks) from analogue audio to equivalent digital audio, and pass this latter to the interface. There are several different digital audio transport formats, and ADAT is one of them. Since your interface has ADAT connectivity, you simply connect the AD converter to the interface with the right cable and your interface suddenly will have 8 more line channels - so that you can connect the synths to the AD converter and "see" them via the interface as normal.
Converters come in all costs and quality, the cheapest being - I gather - the Behringer ADA 8200 and the most expensive... well, sky's the limit. At home I use a RME ADI Pro and it works perfectly. At the studio I have Prims and Lucid.
If you need more than 8 additional channels, ADAT is no longer enough. Then you need a multi channel digital interface, such as the Elf's, which allows you to see up to 64 or 128 digital audio streams - each set of 8 produced by different converter boxes. It gets expensive pretty soon.
I understand the 8200 does already a more than decent job, but James knows more about the specifics than I.
