csound = libcsound.Csound()
csound.setOption('-odac')
csound.compileOrc(r'''

sr = 44100   ; Modify to fit your system
ksmps = 64
nchnls = 2
0dbfs = 1

instr 1
  kchan init -1
  kchan = (kchan + metro:k(1)) % nchnls
  if changed:k(kchan) == 1 then
    println "Channel: %d", kchan + 1
  endif
  asig = pinker() * 0.2
  outch kchan + 1, asig
endin

''')
csound.start()
thread = csound.performanceThread()
thread.play()
# Schedule an instance of instr 1 for 10 seconds
thread.scoreEvent(0, "i", [1, 0, 10])
input("Press any key to stop...\n")
thread.stop()
