Hi Ben, I had a song that was 102 bars long (accidentally inserted several using the insert bars again command) it had 3 different time changes in it. I was frustrated with the fact that I did have 102 bars (too long) so I decided to select all and clear everything.... Now working in the same song, now empty, I try to Insert Bars (32 bars of 2/4 at 300bpm) and they don't show up in the display. I tried to recreate this (I wasn't taking notes): New song: Inserted 32 bars of 2/4 @320 bpm. Put a variety of drums in all over the place. Tried to section the piece into various sections: 1 to 32, 3 to 32 and 32 to 17. (I find this feature hard to use). I played the song a couple times through, pulled the master tempo to 136%, looped playback and then tried to insert more bars. 32 bars of 2/4 @300 bpm, got nothing. Tried the insert more bars again and got nothing. I then selected all the bars and cleared everything 'song is empty'. Again tried to insert more bars and got nothing. Hmm, I am using 10.1.5 (hoping that Jaguar is in my mailbox) with 1A3. Oh yeah with your voice drums. I have never really tested software before, so I hope this stands as an ok bug report.. Later, Gavin.
