What is your writing process?

That is not clear.

Are you entering bass notes into a score, or are you playing them on a midi keyboard?

I assume you are not playing a real bass. You might want to try it, just because it is fun, and you will get the hang of it.

In music, you have to jam A LOT to write anything worthwhile. If you try and do it "logically", in a vacuum so to speak, it will have no life to it.

Do you ever choose a bass patch on a keyboard and just jam??

It is very fun--and it is the way you learn.
