If someone at Yamaha is reading this, could you please release a firmware update for the Yamaha Reface CP so that the toy piano setting plays the hidden grand piano sound instead?
To get the hidden piano sound:
1. Turn Reface CP off.
2. Turn piano sound knob so it rests in between any two settings.
3. Turn Reface CP on.
The Reface CP is one of my favorite small keys piano instruments, and I got one specifically for the hidden piano sound, but it’s annoying to have to go through the above steps and I’m not experienced enough to mod the circuitry.
