Yes, but you have to define the parameters in your orchestra file first.
EG:

sr = 44100
kr = 44100
ksmps = 1
nchnls = 2

instr 60

ivol = p4 ;this is the volume: multipling the signal
ipan = p5 ; this is the paning: float numbers range between 0-1  

  aleft, aright diskin "60.wav", 1
  aleft = aleft * ivol
  aright = aright * ivol 
  outs aleft*ipan, aright*(1 - ipan)  

endin


+++++++++++++++++++++++++++++++++++++++++++++

	       ;vol	;pan (0.0 to 1.0)
i60 0   2    1 	      1 
i60 3   2    1 	      0
i60 6   2    1 	      .5  
i60 9   2    2 	      .5 
i60 12  2   .5       .5

linear amplitude panning works, but not very well, due to the "hole in
the middle" effect (the signal has less power when it's positioned in
the center). a better solution is constant power panning, using
sinusoidal functions to control the amplitudes.

for example, if asig is your signal, and p5 is the panning value between
0 (left) and 1 (right), i guess something like this should work better:

ipan	=	p5*1.570796327	; pi/2

aleft	=	asig*cos(ipan)
aright	=	asig*sin(ipan)

best,

the code looks all right to me, but you are in a better position to
answer your own question: does it compile (i didn't test it)? does it
do what you want (you know that better than me)? if the answer is yes
to both questions, then in must be all right...

good luck with your csounding, jonas.
