nice video.
i made a table that can be assigned to kick instruments in lsdj to get a sidechain effect.
it involves m commands to drop the volume of all the channels and then bring them back up again.
as long as your kick is a fair bit louder than your other instruments it should work alright.
obviously it doesn't sound nearly as good as sidechaining using a DAW, but i made it when i was only using raw lsdj.
the table goes something like this
CMD
0 M44
1
2
3
4 M55
5
6
7
8 M66
9
A
B
C M77
D
E H0D
F
with the other command table being used to create your kick sound.
and you can obviously change that around to create faster/slower release times and such.
sorry, little bit of a threadjack there... but i thought it was kinda relevant.
