Before we get too much further, Satanas, which version of the BeatBuddy Manager (BBM) are you using? If 184.108.40.206, songs with bass will probably not work–for that, you’ll need one of the beta 1.6.x versions of the BBM. I’m going to assume though, that you are using one of the beta versions.
In LPX (I’m using version 10.2.2 so your steps and view may be slightly different)
- double-click the midi bass track (upper part of screen shot)
- in the Piano Roll (bottom portion of screen shot), Select All bass notes (Command A); all of the selected bass notes should change from one color to another (for me, it was Red to Green)
- Select Edit tab (within Piano Roll view); scroll down to Transpose and choose +12 Semitones (second screen shot) I usually do this two times and test within BBM by right-clicking on the midi section I just imported into BBM (I look for unsupported bass notes to give me an idea of whether I’m close or not)
- I will then go back to LPX and tweak the bass midi track by transposing up or down (depending on the key you want to play the song in, it will take some twiddling e.g., on one of my songs, I just added 5 semitones to get it in the key of the original song).
There may be smarter and easier ways to transpose or adjust the bass notes in LPX and I hope that some of these LPX users will chime in with their advice.
Several users find that Reaper works just as well, maybe even easier for them.
