I just downloaded Soundpaint from 8dio. It comes with a free 1928 Steinway piano that is really good. I also bought the 1975 soul guitar and the Palindrome Standard Edition. They also have some other packs (some aimed at film and media composers) and are planning many more. It runs fine inside Unify/Windows. Definitely worth checking out. Looks like John will be showing it on the stream today (10/30/21). Seems to be an exciting and powerful new platform!
