When trying out the stuff you mentioned i put it an octave down and will be able to jam at a happier harmonic space.
1 octave down is a friendly place to be on a 61 key keyboard if you are playing by yourself and you want to take care of the bass. super cool if you get a bass split, then you can play with just a drummer and a singer and it's almost like you've completed the band. takes some practice but if you throw yourself into a situation where you have to do that, you'll sprout wings! like jumping off a cliff. very fun
