Feature Request: Extended Sound Pitch Range in MU4

I have problems with Sound become disappearing when the pitch is out of range of the "Sound" I choose(Muse Sound) and it's not out of range of the instrument(Harpsichord).

I want a feature that extends the pitch range of the "Sound" to 0-127 full range.

Note: I post on the wrong topic. I move it to the correct topic right here: https://musescore.org/en/node/338301
