Hey Andrew, thanks for the quick reply, and you are right--it is when I press the RADIO button that causes the issue; I can get into "chord settings" just fine. Oh yeah, and I seem to recall from my computer music class (YEARS ago...) that you CAN use commas in between the chords to put one one each beat--so sorry I forgot--I didn't even remember that there was a key command for that. I'm more of a keybord inputter than a mouse clicker myself anyway, so that sure works a LOT better. So now what I did was, for instance, select the beat one, and the type "G7,Gb7" (without the quotes) and then it inputs G7 and Gb7 on beats one and two respectively. Could do the same on beat 3. I'm really heavily relying on BiaB for my last year of jazz music studies degree as a jazz guitar major because a) no one to jam with b) no time to play gigs and c) need to memorize tunes and learn patterns. Thanks a lot, and sorry for looking like a dumbass--next time I get a crash, I will refer to KEYBOARD SHORTCUTS! So looks like I can save my $$$ after all. And when the new BiaB for Mac comes along, I will buy that--where can I apply to become beta tester, if needed? OK, never mind--I will save that question for a different thread. Thank you again!
