Start with this circuit: Power + Split
1.) Mini Sequencer + Oscillator + Filter + Mix
2.) Keyboard + Oscillator + Envelope + Delay +Mix + Speaker
Tune both oscillators (refer to the tuning project.) Oscillators can either be set to "consonant" or "dissonant" intervals. In consonance, the are in harmony. In dissonance, they will sound unresolved.
Create a pattern on the micro sequencer that you like. This will become your backing music.
Adjust the filter until you reach the sound you like.
Set mix level 1 low and mix level 2 higher
Play a few notes on the keyboard. The keyboard is like the "lead singer" and will appear louder than your sequencer because nothing is filtering the sound.
Adjust the envelope and delay - these will change yoru keyboard's sound.
