FM-1 parameters can be controlled with these sysex (F0 43 10 pp qq vv F7 sysex format)
EDIT : there is a mistake for Global parameters, they are shifted by 2. I will correct that later.
Other site true values DX7 SYSEX

Here is the complete, comprehensive list of all 155 DX7 voice parameters mapped directly to the F0 43 10 pp qq vv F7 SysEx parameter change format.

:bulb: Quick Format Reminder

  • F0 43 1n pp qq vv F7: Change 10 to 1n where n is your MIDI Channel minus 1 (e.g., 10 is Channel 1, 11 is Channel 2).
  • vv (Value): Must always be provided in hexadecimal (e.g., a volume of 99 becomes 63).
  1. Operator Parameters (pp = 00)

The DX7 processes operators from 6 down to 1. To find the exact parameter address (qq), look up the base hex offset for Operator 6 below, then add the specific operator’s hex modifier:

  • Operator 6: Base offset + 00
  • Operator 5: Base offset + 15 (21 decimal)
  • Operator 4: Base offset + 2A (42 decimal)
  • Operator 3: Base offset + 3F (63 decimal)
  • Operator 2: Base offset + 54 (84 decimal)
  • Operator 1: Base offset + 69 (105 decimal)

:joystick: Quick Calculation Examples

  • Targeting Operator 4 Output Level to max (99):
    • Base offset for Output Level is 10 hex.
    • Modifier for Op 4 is 2A hex.
    • qq = 10 + 2A = 3A
    • vv = 99 in hex = 63
    • Result string: F0 43 10 00 3A 63 F7
  • Changing Algorithm to Algorithm 32:
    • pp = 01 (Global parameter)
    • qq = 08 (Algorithm parameter)
    • vv = 31 in hex (Algorithm 32 maps to value 31) = 1F
    • Result string: F0 43 10 01 08 1F F7
