Bass note to power chord

Windows/Mac MIDI Machines
1

Hey guys! I play bass gtr in my band (a trio) and i use midi bass to trigger a guitar vst to play a second rhythm guitar when the guitarist does a lead or a solo. I want my vst to basically play a power chor based off the note i’m playing on the bass. I used to easily do that in logic pro with the midi environment but i was forced to swith to Garageband and it doesn’t have that function. I know it’s programmable in the harmonizer function inside midi bass but i have no idea how to write the code. I basically need midi bass to output 3 midi notes from what i’m playing. The root, the fith (+7) and the octave above (+12). Can anybody help me do that?
