Well, I did buy the Babyface Pro, and it looks like it's going to work
well.  I am wondering what to do about the balanced outputs you
mentioned though.

I want to connect one of the balanced XLR outputs to an unbalanced TS
input jack on an Ensoniq DP4 effects processor.  I'm almost sure that
any premade XLR-TS cable I buy will have the ground pin connected, since
that's usually considered good.

I currently already have a lot of XLR-TRS fully balanced cables with me
though.  If I simply disconnect the sleeve connection at the TRS end of
one of them, will that work?  What do I really have to do to connect
this output to a TS jack correctly?
