Hi Slammer22,
The Erica Synths - Black 8 Multi is so far the best buffered multiple I have. Being "the best" as in comfortable to use and from a patching point of view. The bad news is that it's sold out :-( I only got one of it and wanted to buy a few more but then I was already too late. I checked this with Erica Synths but it's really sold out :-(
The Black 8 Multi is so logical to use and it has four outputs per input channel, no other modules (with 4 HP width) can do that, as far as I know, in such logical and comfortable way.
Indeed the Doepfer A-180-3 is another good choice.
Other option might be the ACL - Multi II that exists of two parts, a buffered multiple and a passive multiple, 6 HP, so it's comfortable to use while patching.
Good luck in searching for a good buffered multiple and kind regards, Garfield.
