Hi,
First off: Thanks for your program and all the updates - very intuitive and it looks great. 😎
Could you please replace the keyboard scale option by scale x and scale y?
The problem is that if you change from 88 keys to 49, the field of view gets much smaller.
If only the X gets scaled, the keys will become thinner, but the FOV stays the same which makes it easier to see incoming notes.
In my case I use a 37 keys keyboard, and it is very hard for me to play because almost 50% of the notes are not visible.
If you use a 49 keyboard, it's not that much better.
With 88 you have the biggest FOV, but it makes no sense when you don't have so many keys...
