As part of the sampler I am developing a menu system that can incorporate different types of menu layouts and functionalities based on the same input controls. 

Menus I want to make:

- Main menu (scrolling menu in video)

- File selector for selecting files from SD card (in video)

- Bank and slot "grid". Want an easy way of selecting sample slots and copying and pasting them. (in video)

- 8 Channel mixer for volume control and effects

- Midi settings menu 

- Sample trimming for editing start and end of sample

- Sample recording menu

I will be uploading code soon once it's in a better place.

Test rig for developing the menu types. I will eventually use an encoder but just have buttons for left, right and click for now.

A couple of menus that I've made. Still very much WIP.
