Unfortunately, it will not function the way you envisioned it. However, the Soma Ornament 8 sequencer does exactly what you ask for here, and much more. It controls (with 8 knobs) when and for how long the sensors are triggered, and so on, and frees up your hands for doing other things. The adapter connecting Ornament to Lyra also has sensors, so you can play your own notes anytime on top of the sequence running from the Ornament. It’s a lot of fun and adds another dimension to it.
