I have a serious problem when I use turnoff2 to turn an instrument  
off, which uses soundin or diskin. The first time turnoff2 turns off  
the other instrument (instr 2), I get the error:

PERF ERROR in instr 2: soundin: not initialised

When I go on (instr 2 has turned on again and is stopped by instr 1  
the second time), Csound crashes (Terminal prints this message  
indefinetely, QuteCsound hangs on).
I give a simple example below. Thanks for any information whether this  
is a bug or the setting of the instruments must be changed for these  
cases.

instr 1
ktrig1	 metro	 .5
ktrig2	 metro	 1
if ktrig1 == 1 && ktrig2 == 1 then
printks	"ON%n", 0
event	 "i", 2, 0, 10
elseif ktrig1 == 0 && ktrig2 == 1 then
printks	"OFF%n", 0
turnoff2	2, 0, 0
endif
endin
instr 2
asig	 soundin	"fox.wav"
out	 asig
endin


i 1 0 1.5; turns instr 2 off, but with an initialization error
;i 1 0 4; this crashes csound, when turnoff2 stops instr 2 the second  
time

I did some testing here, and can confirm that it happens on several
recent versions too (5.07, 5.08, 5.09).
If you use anegative p3 for the "on" event, and use the event opcode
with a negative p2 to turn if off, then it will not crash. Perhaps
that can give a clue for someone to find the error in soundin.

Thanks for testing and for the nice trick. This is indeed a way to  
solve the problem for the moment. The only thing I'd like to add: I  
don't think it's a soundin problem, because it's the same with  
diskin2. It seems to be a turnoff2 problem.
