Which of the following *realtime* examples executes more efficiently? My 
current project uses *many* of the same type of instrument simultaneously 
(i1/i2), so efficiency will be crucial. And does the answer change if there 
are 8+ of instrument type i1/i2?

1)
instr 1
a1 lfo 1000, 440
gk1 ctrl7 1, 10, 0, 1
outs a1 * gk1, a1 * gk1
endin

instr 2
a1 lfo 1000, 660
outs a1 * gk1, a1 * gk1
endin

i1 0 60
i2 0 60

2)
instr 1
ga1 lfo 1000, 440
endin

instr 2
ga2 lfo 1000, 660
endin

instr 3
k1 ctrl7 1, 10, 0, 1
outs (ga1 + ga2) * k1, (ga1 + ga2) * k1
endin

i1 0 60
i2 0 60
i3 0 60

TIA,
