well, if you play guitar, it would stand to reason that when you choose your guitar samples, you're gonna be able to know what sounds reasonable, what sounds stupid. Some just trust whats there thinking nobody will know the difference. Goes for every instrument. Sometimes the solos are overblown, and the user doesnt know it, they think it sounds impressive.

Absolutely matters if you already play an instrument, and/or know music. As I said when you hear a good singer, you know the track is gonna be good, and vica versa

Even in some of the better ones, there are nuances that dont sound right, usually dynamics. When I use EZ drums I could work a whole complete day 24 hours putting in fills that seem authentic. Then when I replay and relisten i find im editing stuff. The Cymbals are always tricky

and Toontrack adverstises that their stuff is for songwriters, "meet your new cowriter" which is simply not true. Nobody is going to write good songs using their songwriting features, lol. You want the thing to write the chord progression, why not let it right the melody too?

My only fear is becoming reliant on it, i have 40-50 songs that were written away from ANYTHING, so I wouldnt be using BIAB to help me write songs. But down the road I dont want to be turning it on and saying ok, lets write a song,,,
