i realized i hadnt posted this here, and i had come up with some new stuff since i posted it on 8bc
i googled lsdj triplets and only found slorrin's pdf format's hawkfather's tutorial on how to do triplets with the G and H commands. i've been using the D command for triplets, i dunno if this is common knowledge or what, if it is, my bad.
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

here's the formula to remember for "on the go" or "experimentation"
(Ticks x Steps) / 3 = triplet length in ticks
also another thing i realized since posting this, is that you can just use
D00 / ---
D02
D04
D00 / ---
on the entire phrase, put down your notes where you want them, and then get rid of the D commands you aren't using. in each groove, what ever groove it is, the first four steps will be the same for all 16 steps, no matter what length notes you want to use (1/16T, 1/8T, etc.)
now here's where i'm gonna give tips about triplets for other grooves:
this trick will not work for all grooves. the amount of ticks in four steps MUST be divisible by 3. for example:
5/7 will work, because 5+7+5+7= 24.
so the command chain for that would look like this (with a note every 8 ticks)
D00 / --- 5 ticks
D03 5 + 3 ticks = 8, +4 remaining ticks = 12
D04 12 + 4 ticks = 16
D00 /
reversed (7/5)
D00 7 ticks
D01 7 + 1 = 8, + 4 remaining ticks = 12
D04 12 + 4 = 16
D00
(this is all done in my head without a gameboy right now so it might be off, but it should only be off by 1 tick)
something like 3/4 or 4/3 wouldn't work, because 3+4+3+4 is 14 ticks. but if your groove was 3/4/3/5, it would be 15 ticks, making triplets possible on each 5th tick.
D00 3
D02 3+2 = 5, +1 remaining =6
D00 6+4=10
D00 10th tick
because the last step takes up 5 steps, and the first one starts at 0, you only have to place the Delay command on the 5th tick, which is 2 ticks after the second step, because the first step is 3 ticks.
7/8 = 7+8+7+8 = 14+16 = 30 ticks.
D00 7 ticks
D03 7+3 ticks = 10, + 5 remaining ticks = 15
D05 15+5 = 20
D00
just note that you don't have to use any of the D00 commands, it's just put there to make the spacing obvious
i'm not going to go through a bunch of different grooves here. if you can operate a calculator you can figure out whether or not you can use this on a specific groove setting.
