[net.music.synth] Patches for Yamaha TX7, DX7

ae@whuts.UUCP (EHRLICH) (09/19/85)

There are a fair number of people out there who have DX7s and TX7s.  It
would be great to trade patches between users.  TX7 users could trade
cassettes (that's what the TX7 uses for loading & storage) and DX7 users,
disks (or is it ROMs?).  Crossover could be done by anybody with a DX7 and
a TX7.

Anyone interested can send email to me.  I'll post a summary and a list of
people after, depending on interest.

Dear Mr. Ehrlich;

I hate to bust your bubble, but DX-7 users don't use rom's. They use RAM
cartridges, and those suckers are EXPENSIVE, too much so to be mailing around
at random.

There have been some proposals for a way to code the patches on the net as a
down-loadable file, but so far there is no set standard. Dx-7 patches consist
of 155 parameters whose magnitudes are less than 128.

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.
