So where do I go to learn how to play bass on keyboard? I know most of my chords and can play root and fifths no problem, but what notes do you use when moving from chord to chord? As someone said in another post the arranger has no way of knowing what the next chord will be. So are there certain rules to use when going from one chord to another?
Listen to some of your favorite music, and see if you can figure out what the bass player is playing.
If you read music, there's tons of books on bassline construction and transcriptions of bass lines in all sorts of styles.

Transpose to all keys and apply to a bunch of tunes. Sure, it's a lot of work, but that's the great thing about music- there's always something fun and interesting to learn!
