Yamaha DTXpress/DTXplorer/DTXtreme

There are at least a few options for adding inputs through midi 
without buying another module. Roland currently makes something 
called the TMC-6, which, oddly enough, has six inputs. Although it 
is geared toward the latest Roland technology, it is compatible with 
anything that Yamaha puts out. It lists for about $300, but you can 
usually find it closer to $200. It might be overkill to accompany 
the DTXPUII, even though it has only six inputs. Roland used to make 
the PM-16, which, true to its name, had sixteen inputs. I'm not sure 
whether all the inputs were mono, but I think so. At any rate, it's 
still shows up on ebay for under $100, and it's a nice way to expand 
inexpensively. Kat used to make something called the midiKITI, which 
has nine inputs; it fetches $100 or less on ebay. If you see one, 
make sure it's the later Pro version, which has significant 
improvements in velocity curves and layering/crossfading, among 
other things. Rumor has it that Alternate Mode, which now handles 
Kat, is considering manufacturing it again.
