I hope that maybe this helps Sjon. I got this from T-block:
This is what I need to learn, how about you?Here is a routine you can practice every time you get to a keyboard to get you used to playing in all keys. Don't miss a key now, alright? It doesn't matter what key you start at, but I recommend starting at C.
Progression wise, I suggest practicing 7-3-6-2-5-1 the most cuz that is a common progression. Any time you want to modulate to another key, the best way to do it is by playing the 4 chord of your new key with the 5th of your new key in the bass:
Key C

Once you run through this every time you get a chance, you will find it easier to start playing in other keys.
