Thanks for your response Darryl.
My uncle recommended to my dad that I get Pro Tools (my uncle made a lot of money in the biz).
I've been recording guitar stuff, acoustic and electric, both with a Blue Yeti usb mic. I don't have an external instrument like a keyboard.
My goal is to write long songs for a special lady.
I have a 2015 MacBook Pro OS Sierra version 10.12.6
I've been recording on Garage Band and I've liked it. I haven't used Logic Pro but I've assumed it's an expanded version of Garage Band. ?
