delay sync

Hey I was just using the z3ta+2, specifically I was playing with the delay modulator and the sync part of it. What is the difference between say 1d, 1 and 1t sync timings?
 
Thanks 

Thanks. I know dotted whole. But, is a triplet whole just 3 beats in one whole note? Sorry don't really know music theory. 
 
Thanks again

That's odd that it would be 2.66 beats per whole if its called a triplet. Any idea how that number is calculated?
 
Thanks for your help man!

It's not. A triplet means three notes in a space where there would "normally" be two.

Crash course in music theory:
Most current stuff is counted as 4/4, meaning four quarter notes to the measure. Each quarter note represents one beat in that case. Normal math applies, so a note twice as long as a quarter note is a half note and a note half as long as a quarter note is an 8th note. Like I said before, a triplet fits three notes in a space where there would normally be two. So if two eight notes make one quarter note, an eight note triplet does too. You just divide the quarter note into three equal parts. Similarly a quarter note triplet is as long as one half note (two musical beats in a 4/4 measure).

Hope that doesn't leave your brain spinning. These might help:

That one starts with a whole note, then half notes, quarter notes, eights and finally sixteenth (there are more, you could basically keep dividing as much as you want).
A triplet example is in this next image:

That's where I got the number at least.

I'm sure i'm wrong, but now I'm curious how many beats a whole note triplet is too!! :(
 

I see.

I guess what I meant was, in the case of the z3ta+2 delay, a delay would sound every 2.66 beats if 1t was selected as the sync value. Not that you would ever count it like that though.

Alright, enough math. My head hurts. 

Without the explanation, triplet is 2/3 the duration, dotted is 3/2 the duration .
