A couple of 'startup' questions and general comments --
- Does that iPad recognize that a BT MIDI device is connected??
If so, the MD-BT01 is probably plugged in correctly.? (From your
description, it sounds like this is the case.)
- Set the MIDI channel to CH1.? Do you have a program that can
monitor MIDI traffic?? Can you send/receive notes?? (On a PC, I
use MIDI OX; I'm not sure what/if the equivilent program on an
iPad is.)
- MIDI SysEx doesn't have a channel per se.? Devices send an F0
byte, the Manufacturer ID (either 1 or 3 bytes), and end with an
F7 byte.? In between the Manufacturer ID and the F7 can be a
string of bytes defined by the manufacturer, and may only work
with certain products.? There *may* be other tags such as the
Model ID and Device ID (number) to define compatibility or
direct traffice, but these aren't absolutely required to be a
SysEx message.? Some of the gritty details of SysEx were being
flushed out while DX7 was being released, so it wouldn't
surprise me if it cuts some corners in this respect.
- The biggest potential hurdle is connecting the BT MIDI to
editing software that supports the DX7.? Many older MIDI
editor/librarian programs only work (or work well) with specific
MIDI interfaces.? I doubt that something as comparatively
complex as Bluetooth MIDI was part of the discussion.

The setup video on the yamaha
site doesn't really indicate which plug goes in which socket -
hopefully that is evident from the way the loop of wire is
between them,unless they are marked.
I doubt you should need an app to connect bluetooth - that's
in SETTINGS on the ipad,and Yamaha are referring to something
called PIANO DIARY which I presume is a music app,and to
select the comms device within its settings.
To edit the sound parameters on the DX7 would need some
sort of SYSx dumping software on the IPad and the
instructions Grant just provided.

Looking for some insight and assistance here.? I
picked up a Yamaha wireless bluetooth MD-BT01
Bluetooth Wireless MIDI Interface to use with my
DX7.? My understanding is that the device can/could
be used with an instrument that has midi in and out
sockets.? It connects very easily of course, the IN
to the midi IN and the OUT to the midi out on the
keyboard.? The purpose of this was to see if I could
modify some of the DX7 sounds with my Ipad.? I was
able to download an app which allows the Ipad to
recognize the Bluetooth device, but from there I'm
lost.? Is there a particular midi channel on the
keyboard that I need to use?? Or is this an exercise
in futility in that the DX7 is just too old to be
able to use this technology.....?
Thanks to all for your assistance

thanks a lot, that is great.
But from a first check, the DX21 firmware and
that of the DX100 are
completely different. In the DX100 the rom
starts with code and ends
with the voices, in the DX21 it's the other way
round. Also the DX100
uses only 43 bytes per voice, so no simple
direct comparison between
those two. And that although they use the same
MPU (HD63B03XP in DX21
and HD6303XP in DX27S),only difference is the
speed of the processors.
Okay, now I have a reason to desolder the rom
from my DX27s and read
that out... Unless someone has the firmware of
the DX27s?
Cheers, Florian
