Perhaps its a Dexibell Vivo S7 Pro ?



I like it to have the TP400W action but with all the functionality of the S7 instead of the S9

S7 PRO share same technology of actual S7 with several major improvements:
- Better Keyboard: TP 40 Graded Hammer Action Keyboard
- Professional Outputs : 2-XLR balanced + 2-¼” Jack Unbalanced
- 4 parts - 4 pedal inputs
- 8 independent EFX (2 x each part)
- Cosmetics and wooden side panels from S9
- New Human interface derived from S9
- DC-IN with security lock
- DEXIBELL Continuous Sustain Pedal included

That's why it is still called S7 with the addition of PRO
