Which other softwares do you use to supplement BIAB? In this thread, I suggest we only talk about 'semi-automatic' softwares.
I am thinking of the Ezkeys software, and perhaps EzDrummer, both are made by Toontrack.
Captain Plugins, by Mixed in Key, are also relevant.
I tried the demo of ORB Producer Suite and was also very impressed. Perhaps I will buy it in the near future.
For guitar, in theory, RealGuitar seems to be the most appropriate. However, when I used it, I found it a bit clunky and clumsy.
UJam's guitar Softwares are very good. However, at this time of writing, I understand that you still cannot drag the midi patterns into your DAW and have to play it live.
