the error is that it's not possible to have any k-variable in instr 0 
(the header of your csd file).

there are many possible solutions. as you are using csoundqt: what about 
triggering from the live event panel?

if not, perhaps you can describe what you exactly want to do.

below is one possible solution. you need to have two widgets with 
channels "one" and "two". you could even write a list with lineedit or 
whatever -- all is possible ...

iVal invalue is not possible. if you look into the manual, on the left 
side is either k or S.

0dbfs = 1
ksmps = 32

instr Trigger
kStartInsOne invalue "one"
kStartInsTwo invalue "two"
event_i "i", "One", i(kStartInsOne), 3
event_i "i", "Two", i(kStartInsTwo), 3
endin

instr One
aOut poscil .3, 400
out aOut
endin

instr Two
aOut poscil .3, 500
out aOut
endin



i "Trigger" 0 99999
