What do you use for the bass track? garage band or something like that?

For now the bass plays Bm / E / F# what should be Bm ( 7 ) / Em ( 7 )/ F#7

Good tip , buy GuitarPro, it's about 50 bucks and with that you can write your own bass track and other tracks and it playes it with real sounds, not midi sounds. These can be exported from the program as .wav or .mp3 so you can import these tracks in your recording software wether that is reaper or any other, worked miracles for me.
