Ok I Cant play the piano. I can figure out a melody kind of but I mainly record guitar and vocal stuff (my own and covers) for fun but I could really do with a simple way of adding some keyboards, organ or synth tones. Perhaps using a keyboard that has one finger chords as an option. I have an ancient Casio CA 10 and have been messing about with that but its rubbish.
What do I need? do I need a Synth, organ or what? Dont want to spend a fortune and will probably buy used. I mainly record in Audacity via an Audio interface.
