Why do I prefer the sound and interface of scaler 1.8

I’m using scaler 2.3 now, but I prefer the sound and interface of scaler 1.8.
I don’t know if scaler 2.4 can be modified, such as soft piano and felt piano. I won’t use them at all. Finally, I think scale should add a good sweep sound effect to the guitar. A strong piano and a guitar sound like realguitar are enough.
