[Firebox controller for ableton]

spare a knob for an poor midibox bum?

:P

Let me make another attempt at being helpful and ask: Have you considered sites like Futurlec? Of course their stuff isn't as nice as the ones you're looking at by a long shot, and they can be a little slow on the shipping side. It may or may not be worth the trade-off.

Oh, sorry about bringing up the AIN module. I totally thought I was on the ball there.! :-[

If you look at the AIN page:

...you'll notice it mentions you need two for a full-featured MB64. In other words, two is the most a core can support. Another way to find this out would be to see how many components a project can handle, and figure how many modules that equals. Also, I came out of lurking to answer your question... hooray me. :D
