If your DX7 is not responding to parameter changes, make sure that memory protect is turned off. From the manual:

  1. Press the 'Memory Protect' [INTERNAL] button. The display will read 'MEMORY PROTECT INTERNAL ON'.
  2. Press the [-1/NO/OFF] button. The display will read 'MEMORY PROTECT INTERNAL OFF'.
  3. To exit from the Memory Protect mode, press the Memory Select [INTERNAL] button.
    NOTE: The Memory Protect setting will automatically reset to 'ON' every time the keyboard power is turned off and on again.
