Maybe check out [Inaccurate time intervals for a Metronome](https://discourse.processing.org/t/inaccurate-time-intervals-for-a-metronome/2463/10?u=neilcsmith) although using `millis()` instead of `System.nanoTime()`. In general, you can’t rely on your code hitting the exact time required. You need to maintain variables with the target times, and trigger events / schedule the next time when that time gets exceeded.
