So, basically, you’re doing it wrong. 1) In Logic, the drums and bass are going to be on separate tracks when you create the song. The normal range for a bass in Logic in E1 though G3, but this would conflict with the normal range for a drum kit, which starts at B0 or C1. 2) What you do is write the two parts in Logic so that they sound the way you want. Keep drums on one track and bass on another. Make sure you are only using drum notes that are in the kit that you will be using the Beat Buddy.3) Then, when you have it the way you want, you are going to select all of the bass notes, and transpose then down to E -2 for the low note, if you are using one of the kit that have bass at 0 through 31, or up to E 3, if you are using a kit with bass at 62 or 63 through 91.
- Next, select both of your tracks and us the Logic command Edit>Bounce and Join> Join. This will get your bass and drums together. 5) Then save the joined Region as midi.
Now in Beat Buddy, what you have in Logic as separate loops, each of those loops will need to be its own “Main Loop”
So, 6) Each Loop in Logic will need to start at the beginning of the track. Just make more tracks and move each of your loops after the first one onto a track of its own.
7) Save each of those loops as a separate midi file.
8) In BB Manager, click the lower plus button

To make a space for each loop.
- add each loop to the song.
Save the song. You should be ready to play.
