Hi All... On a different topic..... assistance needed.....
|
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
Regards, ?

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
