MOTM

And usually a DI box will convert from unbalanced to balanced as  
well, which is why I think someone suggested using it to connect  
balanced signals to the MOTM.  I think the usual use of a basic,  
passive DI box is to convert high impedance, unbalanced signals into  
low impedance, balanced signals.  It is true that some active DIs can  
amplify/attenuate the signal, and many preamps have Hi-Z inputs and  
can function as DI boxes too.  But bringing this back around to MOTM;  
I think the answer to the original question about connecting balanced  
DAW I/O with the MOTM is that it should work fine with unbalanced TS  
(instrument) cables; i.e. just plug the TS cables from the DAW to the  
MOTM and from the MOTM back to the DAW.  Any decent DAW interface  
with balanced line ins/outs should accept a TS plug and the  
unbalanced signal it carries (and in fact have been designed to do so  
since this would be a common thing to do with most keyboards and many  
mixers, etc).  The thing to realize is that obviously you won't have  
a balanced signal, but unbalanced to and from the MOTM (even though  
the connections on the DAW ins/outs are balanced).  This should not  
be a problem unless you have really long cable runs - running through  
a long snake for example, would probably be a bad idea.  But assuming  
your DAW interface is reasonably near your modular rig (say 10 to 20  
feet; shorter is better) I think you should be fine.

My $0.02.  Ok, now someone correct me.  :-)
