Your third possibility, Alec would be better suited for the beginning player. It takes some familiarizing of CHORD MODIFY, with a lot of trial and errors to come up with what a player wants. CHORD MODIFY does well for people who use pre-sets. It is very good to use when a pre-set has the chord composed as a Major 7th, which can be a real pain in trying to use when playing deep harmonies. You will run into a problem of chord recognition every time. Getting around this is easy by going into GROUP and changing to Chord and CHORD MODIFY TYPE to CEG and click OK. One who is experienced in laying down tracks in COMPOSER will seldom use this or at least, I don't.

Getting back to bass sound - You can go into PART SETTING and change your Bass PITCH POINT. I generally set it to "E" because of the way the keyboard is designed. It will always play the higher F note and it sounds weak. By "E" being the cutoff, when you play an F, it will jump down an octave to the lower F and sound more resonant and fuller. On occasion, (but seldom) in composing a style, I will set it to respond to the higher F. It all depends on the style of music. An electric bass comes through well enough on the higher F. Using acoustic bass is another matter. It gets lost in your chord, with little resonance.

What I have discussed here is for what I have found to work best for a live performance. If you are doing recording work, there will no doubt be times you will want to change your bass pattern or chord to suit your song perfectly.
