Do you think the latency will get very high on a system that uses microphones? Can they be subbed out for the piezo sensors once ready? There's also the issue that with mics you can't control what it reacts to... so if i hit one drum it will trigger other lights most likely, so is it just a matter of switching the sensor? I appreciate you showing me this, looks close to what I want given I can really turn up the brightness.
That looks like a great place to start and could translate easily to my actual use if it just comes down to adding more power + brighter lights.
Thanks you two, before I go and try that, is there any limitations to this method for scaling up? What does the more complicated solution cover that this one wouldn't?
