Hi,
Is it possible to adjust the properties of special tracks? Specifically: the filename parameter of the Sound track?
Here's what I'm doing now:
#Add a Sound track sound_track = c4d.CTrack(sound_obj, c4d.DescID(c4d.DescLevel(c4d.CTsound, c4d.CTsound, 0))) sound_obj.InsertTrackSorted(sound_track) #Set the Sound property to the wav file NOT WORKING sound_track[c4d.CID_SOUND_NAME] = "Test.wav" if debug: print "sound_track[c4d.CID_SOUND_NAME] = ", sound_track[c4d.CID_SOUND_NAME] #Tell C4D something has changed c4d.EventAdd()
Unfortunately, it's not working. I get this error:
"IndexError: Invalid key type."
Any ideas would be greatly appreciated.
Thanks,Donovan

Hi, please set the filename via the BaseContainer from GetDataInstance().
bc=sound_obj.GetDataInstance()
bc.SetFilename(c4d.CID_SOUND_NAME, "Test.wav")Cheers, Sebastian

That will add the text location of where the sound file is located to the field.
But C4D doesn't seem to actually load the file this way. There seems to be a missing step needed that tells C4D to load it.Here's a full example:
import c4d from c4d import gui def main() : obj = doc.GetActiveObject() sound_track = c4d.CTrack(obj, c4d.DescID(c4d.DescLevel(c4d.CTsound, c4d.CTsound, 0))) obj.InsertTrackSorted(sound_track) bc = sound_track.GetDataInstance() path = "\\Users\\user\\Desktop\\moviemix.wav" #The path to the .wav file bc.SetFilename(c4d.CID_SOUND_NAME, path) #Set the Sound property to the wav file sound_track.Message(c4d.MSG_UPDATE) c4d.EventAdd() if __name__=='__main__': main()
Any idea how to get C4D to update and load the sound file. Based on the text in the field?

Hello?
I've tried this a bunch of ways. And even though the file is there in the container. It's not being loaded:
import c4d from c4d import gui def main() : obj = doc.GetActiveObject() sound_track = c4d.CTrack(obj, c4d.DescID(c4d.DescLevel(c4d.CTsound, c4d.CTsound, 0))) obj.InsertTrackSorted(sound_track) bc = obj.GetDataInstance() bc.SetFilename(c4d.CID_SOUND_NAME, "C:\\Users\\user\\Desktop\\moviemix.wav") #The file **is** there in the container. But it's not being loaded into C4D! print bc.FindIndex(c4d.CID_SOUND_NAME) #Even trying to **force** an update does nothing! sound_track.Message(c4d.MSG_UPDATE) sound_track.SetData(bc) obj.SetData(bc) c4d.EventAdd() if __name__=='__main__': main()
It works properly in C++ using SetParameter:
BaseObject *sphere = BaseObject::Alloc(Osphere); doc->InsertObject(sphere, NULL, NULL); CTrack *soundtrack = CTrack::Alloc(sphere, DescID(DescLevel(CTsound,CTsound,0L))); sphere->InsertTrackSorted(soundtrack); soundtrack->SetParameter(DescID(DescLevel(CID_SOUND_START, DTYPE_TIME,0L)), doc->GetTime(), DESCFLAGS_SET_0); Filename file = GeGetC4DPath(C4D_PATH_DESKTOP) + "moviemix.wav"; soundtrack->SetParameter(DescLevel(CID_SOUND_NAME),file,DESCFLAGS_SET_0); EventAdd(); return true;
Is this a bug?
Am I doing something wrong?-ScottA

Hy Scott,
I tested your code with the same results that you get. What I find strange, once you attempt to load a wav in this manner, you also can't load the wav "manually" afterwards. Does not work anymore, on the "self" constructed Track ...
Cheers,

Hi
I just figured this out:
instead of:bc = obj.GetDataInstance() bc.SetFilename(c4d.CID_SOUND_NAME, "C:\\Users\\user\\Desktop\\moviemix.wav")
try:
bc = sound_track.GetDataInstance() bc.SetFilename(c4d.CID_SOUND_NAME, "C:\\Users\\user\\Desktop\\moviemix.wav")
for me, this did the trick

I know this is an old thread, but I just happen to be attempting this on a project of mine. I am using this code in a Python node in Xpresso. The creation and removal of the CTrack is working perfectly, but the setting of the file path does not. Anything obviously wrong with this code?
def main() :
global Output1
Output1 = 1
bc = myObj.GetDataInstance() #myObj is a Null in the scene and used as an input port
myTrack = c4d.CTrack(myObj,c4d.DescID(c4d.DescLevel(c4d.CTsound,c4d.CTsound, 0)))
if myTime == 1: #myTime is another input, taking in the current frame so only creates on frame 1
myObj.InsertTrackSorted(myTrack)
bc.SetFilename(c4d.CID_SOUND_NAME, mySoundFile) #mySoundFile is a filename input port
Output1 = 1
c4d.EventAdd()
elif myTime == 0:
for track in myObj.GetCTracks() :
track.Remove()
c4d.EventAdd()
Output1 = 1
return()I am trying to make this a portable rig so that I can link to a file in the user data of the master Null and have that file trickle down into a sound track and a Sound Effector.
