Hi. I just bought the BIAB Ultra Pak 2019 for Mac. I was super excited to try the soloist feature described in the instruction video showing how to "create much better solos" by having the melody track influence the solo. I was hugely disappointed when I discovered this option is not available in the "create soloist" dialogue box of the Mac version. Why? Please, please include this feature in a future update. Being a beginner it took some hours of preparation before I could get to the point where I was ready to attempt that feature, only to find out it was not available.
