SL with automap looks very cool. The automap concept seems like it should have been implemented a long time ago, it's a no brainer in retrospect
Let the machines talk and agree on their communications scheme, and let me make music. However, it depends on native support in the host application so that introduces its own share of problems. I guess that soon there will be different controllers by different manufacturers which support automapping...that will be a good time for everybody
Faderfox: cool concept, too expensive for what they are. I'll probably just rip off their layout and build a midibox that incorporates 4 or 5 of those things, for about $100.
