Eighth note triplets are cool too, especially for tremolo.
With a bit of math, you can calculate the ms or hz from the tempo and note value if needed since not all time parameters can be set by tap tempo.
If you're lazy like me, there's several online calculators that will do it for you. Google "bpm to ms calculator".
Tap tempo and note values are the best. Effects usually sound better when they are synced up to the tempo of the song. Sounds less chaotic and can sit in the mix a bit better. Sometimes chaotic is a good thing though. :encouragement:
