Triplet groove:

This way, if you skip every fourth step in a sequence it all adds up to a triplet without shortening the pattern or disrupting the mean speed, and you can switch back every even four steps after you changed the groove.

This is how I usually do it in trackers, but I guess it might not be the most convenient way in LSDJ.

Again, it's all math. If your "main" groove is 8 ticks/16th note, a triplet 8th note should be 10 and 2/3 ticks long. One way of achieving this is to use grooves like this:

Regarding the first method, which I still use a lot.

1. PDF is using an initial groove of 3. So making a new groove of 4 won't sound right if you're keeping your groove at 6. You'll need to change it to 8, unless you want double-speed triplets.

2. When you're fixing the groove of the other tracks, make sure that you're making those tracks with the groove of 6 and not the one of 8.

That's precisely what I'd posted above... o_0

I cant send anyone there willingly.

"It's basically just math. LSDJ's default groove is 6/6, which means each step is six ticks long. the first triplet is for a quarter phrase.

quarter phrase = 24 ticks (4 steps @ 6 ticks per step)
counted as 23 ticks (i'm counting 0 as the first tick because it makes the math easier to understand.)

so the four steps start on ticks 0, 6, 12, and 18.

for triplets at this groove, you need each of the three "steps" to last 8 ticks, which would be 0, 8 and 16.

luckily the delay command also counts in ticks

0 C3 ---
1 C3 D02
2 C3 D04
3 -- ---

check that out, its a triplet

that's because we're starting the first step at 0 ticks, the second step at 6 ticks + 2 delay ticks, and the third step at 12 ticks + 4 delay ticks.

for a half phrase triplet, you're fiting 3 steps into 48 ticks. 48/3 = 16 ticks per "step" . needing a note on ticks 0, 16, and 32. so if we put in

0 C3 ---
1 -- ---
2 C3 D04
3 -- ---
4 -- ---
5 C3 D02
6 -- ---
7 -- ---

we have one note on tick 0, one note on tick 12 + 4 delay ticks, and one note on tick 30 + 2 delay ticks.

incase you actually want to do a full phrase triplet it would be 96 ticks / 3 =  32 ticks per "step", steps needed at 0, 32 and 64

so that would just be

1 __ ___

0, 30 + 2, 60 + 4

here's the formula to remember for "on the go" or "experimentation"

(Ticks x Steps) / 3 = triplet length in ticks" thanx to HandHald Heros

could you link  it please?

Found it, thanx!

Oops, edit above, saskrotch explains.
Amazed I didn't think of it myself a long time before... but then, I did not rtfm.
Much simpler than playing with hops.

I seem to remember Saskrotch (I think?) doing a pretty useful triplet tutorial on that other site a few months back. I could totally be talking out of my ass though.

How do you do a "D" command triplet?

D command triplets are less hassle surely?

I watched "The artist formerly known as PDF"'s youtube on how to do a triplet on lsdj.

However, this just shortens that loop and that loop will no longer sync with the rest of the song...

Any way to correct this?

I did change the groove in the other tracks, but now those parts are shorter no longer sound right. The triplets should conform to the measure, not the other way around!

Thank you in advance!
