The Swiss Army triplet is one of the most useful hybrid rudiments. Three notes per group in triplet feel: flam-R-L (a flam followed by two alternating singles). In 6/8 it lays out as two groups per bar — flam-R-L · flam-R-L — beamed in the standard two-threes pattern. The flam lands on the downbeat and on beat 4 (the second dotted-quarter pulse).
Compare to its neighbors. The flam accent spreads the flam-R-L pattern out over straight 8ths in 4/4; the Swiss Army triplet is the same flam-R-L shape but cast as a triplet pulse, which 6/8 expresses cleanly without tuplet brackets. The flam-tap is flam-R-R (same hand on the tap); the Swiss Army is flam-R-L (alternating tap). That tiny change re-shapes the feel — the alternating tap means hands flow through the rudiment instead of one hand doing all the work.
Why "Swiss Army"? Because it's the multi-tool of hybrid rudiments. Move the second note to a tom and you have a one-handed roll with a snare flam; add bass drum on the flam and you have a fill phrase. Pipe-band tradition through to modern fusion — the same shape, infinite uses.
The renderer notates the grace stroke explicitly using the engine's grace-note plumbing: a tiny lowercase l or r sits ahead of the flammed downbeat, drawn with the canonical flam slash glyph. The main note carries uppercase sticking and an accent.
