It isn't just BIAB ... the same people seem to disdain audio loops, MIDI, Garage Band, ACID, backing tracks, Karaoke.... anything related to music that isn't being played by a person

Although I HAVE gotten a negative response from SOME creative people about automated music, I have gottem some very positive reactions too. My conclusion is that the deciding factor of whether or not somebody is going to like BIAB is :

POSERS don't like stuff like this. To them, creativity and music (or art or literature bla bla woof woof) are means to an end, and the end is having a certain image.

On the other hand, I've noticed that people who are comfortable with who they are, and who aren't looking to impress anybody, and who just LOVE being totally immersed in the music-making process... these people pretty much always get excited when they are exposed to creative tools like BIAB.

I think its why this forum's participants are so noticeably lacking in pretense and full of sincere helpfulness. (That ain't the case in MOST forums!... but it's characteristic of the personality that is attracted to innovative tools)

So, next time you introduce someone to BIAB and they turn their nose up and then insult you, remember that's what happens when you cast pearls before swine. They trample the pearls underfoot, then turn on the person who cast the pearls.
