Thanks so much! I definitely encourage still going for the idea yourself, there are quite a few hurdles we didn’t anticipate from the idea alone. Making each melody of an instrument different in isolation but not sound cacophonous all together took several iterations. And making the merge tiers rewarding also took a couple tries.
Good to know it was crackling for you. We had to try and balance the audio buffer size with the lag it produced - reducing the chance of crackling on some browsers (larger buffer) meant a higher chance of the audio being out of sync. Was definitely hard to get right in all circumstance :/
