You could have it so you just buy the RealDrum feature and it will enable the RealDrum picker for those that just want drums.
Or, another option for the UserTrack feature.
And, users can do all this without having Biab or needing to learn it.
It all works with just those few files in a basic package.
At the moment it will even give you a 30day trial, you could leave it like that so it works with just loops and they can register for free to get the serial to enable loops to keep working after 30days. Or you could include 1or2 RealDrums and 1or2 RealTracks that will work for 30days then after that just the loops will work after free registration ???
The basic free loops version will give every DAW a Chord track and you can have the midi chord tack drag option, this alone is good reason for them to download it. Get the midi notes in that track and that will give them midi chords for virtual instruments to follow in their DAW.
With 48kHz/24bit RT/RDs also this will definitely get it out there.
It's like UJAM
https://www.ujam.com/they give you a 30day trial for their Drums, Guitars and Basses.
They are Real Playing on Real Instrument that will follow a chord track, like BB Chord Output midi track.
