I've tested with some of these styles.

If midi drums aren't there then they are replaced with RealDrums of the same quality. smile

(For those who need an interpretation: BIAB doesn't replace "no signal" with "sound". I. e. no midi drum no RealDrum.)

It appears that these styles are indeed "qad" generated: Take an existing (midi) style, replace some midi instruments with RealInstruments, mute the other/delete their content and save with a different name and characteristics. Don't bother about cleaning up.

For 99 percent of all users it doesn't matter. For 80 percent of the rest it's annoying and only a few might encounter a problem.
