Jick Duck, with respect to fills, it may also be possible to assign them to AB, BA, etc. I have not tried this but check it out.

As a generalization, a software based system will be a compromise when compared to the control surface of a keyboard. I have been at this now for about 2 years and am quite use to it even for live performances. Once you are properly setup you will find the software based system just as reliable as any other. That is not to say that you won't have some crashes while you are installing new software, instruments, effects and so on. If you work at it you will prevail - I am certain!!!
