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...
