Having a little trouble creating an entire jam with JUST the PO Modular 400

So I have been trying to create a jam with ONLY the PO Modular 400 and im finding it quite hard to make something outside of the typical bleeps and bloops. The sequencer is a little bit limiting and it's hard to create "sections" to build song structure like AB AB C AB. One route I am trying is to patch the square OSC to the clock in to slow things down and then up the PWM to "freeze" the note...
