A preset library for instruments

[0b5vr]

It's probably related to #88 but that is about having 4klang compatibility so let me open a separated issue.

Motivation

The main motivation is to make people create music on sointu without knowing how to design instruments.

Because making an instrument requires knowledge of both basic synth and stack data structure! That's pretty hard for beginners.

Possible solutions

Having a preset library or a feature to load such libraries might be very cool to have.

• Epic: Have a dedicated preset library browser as industry VSTi synth does
• Great: A simple dropdown to select instruments from a library
  • You would probably be able to load a set of instruments from a song file
• Still good: simply having a UI to load/save instruments

It's a famous episode that Yamaha DX7 used to be popular thanks to its expressive presets and ability to load expansion cartridges.

Like, imagine having a "Virgill preset library". That would motivate people to make 4k music.

Current workaround

Copy and paste feature exists; it requires interacting with yaml file though, which is a bit spicy for non-coders.
