I recently read that negative instrument numbers will turn off the last playing instance of an instrument. Didn't realise this before so tried it to no avail:

instr 1
    a1 phasor 60
    outs a1, a1
endin

...

i 1 0 10
i -1 1 1

this reports "could not find playing instr 1.000000"

Also I saw an example here that says event_i will handle the negative instrument numbers too. (http://write.flossmanuals.net/csound/b-triggering-instrument-instances/)
Tried the following along with the above instr 1, and rather than turnoff the instrument it created another instance.

instr 2
    event_i "i", p4, 0, p3
endin

...
i 2 0 10 1
i 2 1 1 -1

Is my syntax right etc?

yes, and the chapter in the floss manual is about midi, so the 
instrument instances are called with an indefinite duration.
