I found csnd6.doubleArray and solved this issue.

Thanks

I continue working in the port of TamTam (a python application)  from csound 5 to csound 6.

Now I found the app used csoundScoreEvent to play notes.

I get a error with the arguments then I have two questions:

1) It's possible use InputMessage to substitute the use of ScoreEvent?

2) If not, how I should define the array at the python side?

  

c.ScoreEvent.__doc__

returns:

'ScoreEvent(Csound self, char type, double const * pFields, long numFields) -> int'

but modifying my example to use it:

from gi.repository import Gtk

import csnd6

import array

orc = """

sr = 44100

kr = 4410

ksmps = 10

nchnls = 1

; Instrument #1.

instr 1

   kamp = 30000

   kcps = 1

   ifn = 1

   ibas = 1

   ; Play the audio sample stored in Table #1.

   a1 loscil kamp, kcps, ifn, ibas

   out a1

endin"""

c = csnd6.Csound()

c.SetOption("-odac")

c.CompileOrc(orc)

c.Start()

c.InputMessage('f 1 0 131072 1 "beats.wav" 0 4 0')

perfThread = csnd6.CsoundPerformanceThread(c)

perfThread.Play()

def clicked_cb(button, c):

    a = array.array('d', [1.0, 0.0, 2.0])

    print a, len(a)

    c.ScoreEvent('i', a, len(a))

win = Gtk.Window()

btn = Gtk.Button('Play')

btn.connect('clicked', clicked_cb, c)

win.add(btn)

win.show_all()

win.connect("destroy", Gtk.main_quit)

Gtk.main()

I get the following error:

Traceback (most recent call last):

  File "button_se.py", line 36, in clicked_cb

    c.ScoreEvent('i', a, len(a))

  File "/usr/lib64/python2.7/site-packages/csnd6.py", line 2180, in ScoreEvent

    return _csnd6.Csound_ScoreEvent(self, *args)

TypeError: in method 'Csound_ScoreEvent', argument 3 of type 'double const *'

Thanks in advance,
