Add Pads

[Revisto]

Is your feature request related to a problem? Please describe.
We can have a pads section like this as an example:

https://www.onemotion.com/drum-machine/

Describe the solution you'd like
Well we can use view switcher, we already have the feature to play drum parts when they are clicked on. We need to add shortcuts for playing drum parts as well.

Additional context
We can potentially add MIDI keyboard support here as well, it needs investigation though.
