Same sound as 7120|2, 7120|4 but there is fewer notes?
Not quite. If the song is played back, the section beforehand (as you've indicated) is both a kick and a synth hit, while that singular note is just the kick.I can see why there could be confusion, as the synth hit feels like it bleeds into other sections.
These all should be doubles since they are the same sound
This should be a triple.
