Model Selector for instruments

[RukoBlood]

Is your feature request related to a problem? Please describe.
I want to change some models, for example, I don't like that square and saw wave looks like lazers, i like the og (keyboard) variant more. Why model manager? Because some people like lazers more.

Describe the solution you'd like
A menu in settings, where you can select model of an instrument

Describe alternatives you've considered
I really don't know... Maybe you have other ideas...

Additional context

1. I really don't like lazers as sqr and saw waves.
2. It may be a stupid idea...

No hate but aren't the lasers in the program were modeled after the ones from Animusic's Stick Figures? And lmao, don't the square and saw synths turn into keyboards when their polyphony is more than either 3 or 4?
