"In case you've forgotten what you need to do to your DX7 to make it able to receive incoming SYSEX messages, you need to set "memory protect internal" off, and then just send the data from your computer."
no irán por ahí los tiros?
si está ampliado es más complicado:
" If you have a Grey Matter E! card installed, it's slightly more complicated: Press "function", then "operator select" twice to select the "memory" page, push button 31 twice (Memory Protect Internal) and then "off". This disables the memory protect. Then press "function", then "operator select" four times to select the "keyboard control" page, push button 2 (Midi in filters: SYSEX) and then "on". This enables SYSEX data transfer. You are now finally ready to send the data from your computer.
On the DX7II-d, you need to turn memory protection off (Button #14), set the device number on the keyboard to the device number under which the sysex was originaly saved (button #32), and set "MIDI IN" to "normal" (button #29). If you don't do this third step, you get no error message and no hint of what is wrong, but the keyboard just doesn't accept the sysex data. "
