How can i make my synth leads polyphonic?
I'm relatively new to garageband, and I've got a midi controller set up to play with the different instruments they have, but I've noticed that unlike the steinway digital instrument, all of the instruments under "synthesizer" will only play one note at a time, that is, monophonically. Is there a way to make my synthesizer in garageband play more than one note at a time? thanks!
