Very nice bundle with practical nodes!
Going to built on that in audio-lab, planning to add more musical nodes, like metronome with this simple strategy, sequencer and so on.

Couple of ideas-questions:

• Are params exposed? Seems like composite node doesn't pass them through, right?
• Would you consider making params observable? UI may need to react and reflect changes done to the params. Can be done via events or observables, for reference element-props
