DOP (either version) use Standard 1.1 or Standard Pro 1.1
OPB, OPBk use NP Big E-Piano and Bass
I did two version of the DOP. DOP1 is just the drums from the source midi, remapped for Standard 1.1. DOP2 adds drums cues to the keyboard only sections. This may be a good rehearsal version, or you may just prefer it.
Package includes the 4 .sng files, midi part files, and chords and lyrics pdf.
Source midi is a commercial file, and is not included. Thanks to Sainter5 for making the file available for arranging.
