Hey, is there a way to either use two speakers and play two different melodies simultaneously or use one speaker to play two different parts? I'm trying to play a song and I want both bass and melody to play from the boe bot

You can't play two independent tones and you can't use two speakers although you could drive them in parallel with a simple passive filter for each (for low and high tones).
If you really want two independent sound channels, use a Propeller. There's a nice 4-channel synthesizer in the Propeller Object Exchange that does 4-part vocal harmony synthesis (in stereo!)
