Here are two programmes that manipulate DX7/TX7/TF1 bank and voice files.
The programme "bp" enables you to create, add, delete and print banks.
The programme "vp" simply prints a single voice from a file.

  There is nothing included here that will transfer the MIDI data to or
from your synthesizer.  I have no recommendations for what computer and
software combination to buy to do this -- I find it all pretty poor.
If you have the facilities, I encourage you to build something for yourself.

  Included are some single voice patches and some banks.  The voice patches
came from Mike Hawley (via a very circuitous route) sometime in 1985.

  I hope you find this useful.  I claim no copyright on this software, you
can use it for whatever you want.  The patches were given to me free for the
purpose of sharing them.  I hope you share them as well.

  I'm interested in changes or improvments anyone makes.  Perhaps this
software can expand into something bigger.
