Right.  Time for a preliminary response to the mail I've received.

About 10 people have replied with interest in some sort of DX7, TX7 patch
exchange.  Responses have also covered the two points made above.  I'll be
really busy and then gone for the next 2-3 weeks, so my promised summary will
appear soon after that.  I'll think about a reasonable format for a parameter
description file, everybody out there give it some thought too.

You know, if those RAMs are so much, it might be economical for you DX7 owners,
for the price of ~8 of them, buy a TX7.  You could do all sorts of marvelous
stuff with the additional tone generator, and you could use $1.50 cassettes
to store voices.
