Deprecated methods in csound 6

These methods do not exist in csound 7 but code can be written which supports the same functionality

spin / spout

setSpinSample and addSpinSample

csound = Csound()
...
# Csound 6 only
csound.addSpinSample(frame, channel, sample)

# Portable version (csound 7 and 6)
spin = csound.spin()
spin[nchnls * frame + channel] = sample

spoutSample

# Csound 6
samp = csound.spoutSample(frame, channel)

# Portable version (csound 7 and 6)
spout = csound.spout()
samp = spout[nchnls * frame + channel]

clearSpin

# Csound 6
csound.clearSpin()

# Portable version
spin = csound.spin()
spin[:] = 0

queryGlobalVariable

In general, for data exchange with csound it is recommended to use channels or tables.

# Csound 6
ptr = csound.queryGlobalVariable('gkcounter')
if ptr is not None:
    # do something with ptr...

# Portable version
value = csound.evalCode('return gkcounter')

# Or better, using the performanceThread with process queue
thread = csound.performanceThread(withProcessQueue=True)
...
value = thread.evalCode('return gkcounter')
