I'm in agreement that some of the bass parts get a little 'busy' and may not be what "I" would do or my preferred bass player might do ... The new 'simple' feature is nice to have !

My process is much the same as Noel's. BIAB is the starting point and I'm not there too long. Just long enough to do the chord arrangement, basic instruments etc, then it's off to Real Band for the real work.

Once in RB, I will regenerate a bar, a few notes of a bass track until I get something acceptable for the tune at hand. (NOTE: There IS a bug in this process. If your tune has any tempo changes in it, the regen will also erase a few bars after it (arrggh - Hope this gets fixed soon !)

There are some tunes with 'signature' lines. These and the ones you feel just don't cut it, can always be hand-written in midi, and now with VST, apply Garritan or other for the bass rendering... here's an example of a 'sig' bass line that just HAD to be done in midi... with the Garritan Jazz & Big Band upright bass applied.

Don't fault the tool. It's great at what it does. You need to be creative with how you use it. It's amazing to me that Real Tracks even work !! Imagine what is involved. Any infinate number of chord progressions, tempos etc, and to try to intelligently generate a 'part' out of small phrase samples is just staggering to me !
