Hi, Andy. Thank you for the compliments (aww, shucks ).
The v1 file is for DOP, or drums only.
The v2 is for one-press bass (OPB).
I usually try to post the song in the original key for all users.
To accommodate your request to transpose, in my notes to my post with the song, I mentioned that I included a MIDI file that I had transposed to the key of F. All you had to do was copy and paste it over the existing Intro section in the v2 version and voilá, you would have had an OPB in the key of F. You can try it out and see if you like mine or yours better.
Sorry if I didn’t make it clear enough but glad you were able to transpose it on your own.
