Was it based on the frequency of the click?

Probably not, eh?

Probably yes, because the frequency of a note doesn't change based on how quickly the next note is played after it.

Guess I misunderstood. The first time you said "frequency of the click" -- I would personally respond with clicks per second.

"Frequency of the note" in your next comment clears it up. It probably was that, you're right.
