Whoahhh?
What the heck am i doing wrong!

I just bounced a song (bounce mixer channels all tracks) and just listened to each track and BANG! I'm getting the bass track from another song of mine?????????
Tried again, same result. WTF hahahahahaha?
All of the other tracks are ok.

Ok here's what i just tried.

TEST 1:
Bounce the bass only, saved this to desktop, then dragged/copied this into the song's bounced folder. Played this, BOOM! It's the bass from another song???

TEST 2:
Bounce the bass only, saved this to desktop, RENAMED the track to "bass part", then dragged/copied this into the song's bounced folder. Played this it WORKED!


Looks like it's allergic to the name "bass" lol! First time this happens.
