To keep things really short, in order to do what you want with the current BeatBuddy capabilities, you are better off making 2 real song parts VERSE (main part 1) and CHORUS (main part 2). Then just make PRE-CHORUS a transition fill for VERSE.
You will use this in a live setting like the following:
- Press BB once to start the beat. Your VERSE main part 1 will play for as long as you wish.
- Press BB pedal and keep holding it. Your PRE-CHORUS transition part will play for as long as you are holding the pedal.
- Release the BB pedal hold. Your CHORUS main part 2 will play for as long as you wish.
- Hold the BB pedal for a little while. You are now back to point 1, and your VERSE main part 1 is now played.
Now adding the BRIDGE into the mix is a just a little bit more difficult, but if you know for sure you are intending to use it sometimes after the chorus only, you can make it into a transition back from CHORUS to VERSE. Having it that way, you can either play BRIDGE for some time while holding the transition between CHORUS back to BRIDGE, or release the hold almost immediately, playing no BRIDGE at all.
If you need to play something like CHORUS - BRIDGE - CHORUS, you can try making your BRIDGE a fill for the CHORUS instead.
The most amazing thing in the BeatBuddy is that even with all its current implementation’s limitations and tricky parts, it still allows for almost complete freedom when controlling your beat! Sometimes you just need to open your mind for solving tasks in a non traditional way, and not just being pigeonholed into standard songs parts division, trying to replicate that structure in the BeatBuddy song.
Simply be creative!
