Hi,

I have this adapter, too. It's powered by MIDI, and not every device provides this power (and if so, at the required voltage). Dave Smith's Evolver and Mopho don't, for instance. Does the adapter's LED start blinking when it's plugged in, and your DX is turned on? If not, you're probably SOL.?

Here's some random info about other products using the same "feature".?

Thanks to everyone for the assistance.? The midi adapter actually has markings on it reading on one, IN and the other OUT. ?? I will continue to try your suggestions.? And yes, there is a Yamaha app?
that you can download onto the Ipad which gives some great sounding piano sounds. ? That is what I'm trying to accomplish.? Again, thanks for the help.?

Kind regards,?

David Covino?

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

Hi Michael,

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
