I don’t have a whole lot to say on this one except that, for a small hardware studio, it’s a no-brainer. You get 8 ins and 8 outs and you can make and save your own custom routing configurations and channel settings. I can program settings for a few different set ups in here and, with a turn of a dial, I’m instantly set up with no re-cabling, daisychaining or any of that. Best part, these are extremely cheap these days. I got mine in a pawn shop for $30 and this is about in line with what you can get them for on fleabay these days. If you need connectivity with a modern computer, you’ll probably want to go a different route and there are lot of different options and price ranges (though there is a version of this same kit with USB capability). But if its just a few keyboards, samplers and drum machines you want to have communicate with each other, look no further.
*Tip, if you find that you save a “patch” and it isn’t there when you start it up the next time, you probably need to change the battery. It is of the C2032 variety and it’s a quick and painless fix with no soldering needed. You won’t have to do this often but as old as these are now, it’s very possible that you may need to do it when you get it.*
