I have BIAB 2018 complete. I have been updating it yearly for what sees like forever. So What does VArranger and one Man Band offer me that I would want to spend more $ on them?
Take a look at this video of Varranger and a Motif XF for a simple explanation. https://www.youtube.com/watch?v=AsEhOo2Jezw
The problem is not the problem...The problem is your attitude to the problem.
