GetSetMediaItemTakeInfo()

void * GetSetMediaItemTakeInfo(MediaItem_Take *tk, const char *parmname, void *setNewValue)

get (or set) different take parameters

• "P_TRACK" : pointer to MediaTrack (read-only)
• "P_ITEM" : pointer to MediaItem (read-only)
• "P_NAME" : char * to take name
• "P_SOURCE" : PCM_source *. Note that if setting this, you should first retrieve the old source, set the new, THEN delete the old.
• "D_STARTOFFS" : double *, start offset in take of item
• "D_VOL" : double *, take volume
• "D_PAN" : double *, take pan
• "D_PANLAW" : double *, take pan law (-1.0=default, 0.5=-6dB, 1.0=+0dB, etc)
• "D_PLAYRATE" : double *, take play rate (1.0=normal, 2.0=doublespeed, etc)
• "D_PITCH" : double *, take pitch adjust (in semitones, 0.0=normal, +12 = one octave up, etc)
• "B_PPITCH", bool *, "preserve pitch when changing rate"
• "I_CHANMODE", int *, channel mode (0=normal, 1=revstereo, 2=downmix, 3=l, 4=r)
• "I_PITCHMODE", int *, pitch shifter mode, -1=proj default, otherwise high word=shifter low word = parameter
• "GUID" : GUID * : 16-byte GUID, can query or update

Parameters

MediaItem_Take *tk,
const char *parmname,
void *setNewValue

Returns

void *

Example

C++

void DoInsRndFileEx(bool RndLen,bool RndOffset,bool UseTimeSel)
{
	if (g_filenames->GetSize()>0)
	{
		int filenameindex=rand() % g_filenames->GetSize();
 
		t_vect_of_Reaper_tracks TheTracks;
		XenGetProjectTracks(TheTracks,true);
		if (TheTracks.size()>0)
		{
		PCM_source *NewPCM=PCM_Source_CreateFromFile(g_filenames->Get(filenameindex));
		MediaItem *NewItem=AddMediaItemToTrack(TheTracks[0]);
		MediaItem_Take *NewTake=AddTakeToMediaItem(NewItem);
		double TimeSelStart=0.0;
		double TimeSelEnd=NewPCM->GetLength();
		GetSet_LoopTimeRange(false,false,&TimeSelStart,&TimeSelEnd,false);
		double ItemPos=TimeSelStart;
		double ItemLen=NewPCM->GetLength();
		double MediaOffset=0.0;
		if (RndOffset) 
		{
			MediaOffset=(NewPCM->GetLength()/RAND_MAX)*rand();
			ItemLen-=MediaOffset;
		}
		if (RndLen) ItemLen=((NewPCM->GetLength()-MediaOffset)/RAND_MAX)*rand();
		if (UseTimeSel) ItemLen=TimeSelEnd-TimeSelStart;
		if (!UseTimeSel) ItemPos=GetCursorPosition();
		GetSetMediaItemTakeInfo(NewTake,"P_SOURCE",NewPCM);		GetSetMediaItemTakeInfo(NewTake,"D_STARTOFFS",&MediaOffset); 
		GetSetMediaItemInfo(NewItem,"D_POSITION",&ItemPos);
		GetSetMediaItemInfo(NewItem,"D_LENGTH",&ItemLen);
		Main_OnCommand(40047,0); // build any missing peaks
		SetEditCurPos(ItemPos+ItemLen,false,false);
		Undo_OnStateChangeEx("Insert random file (Extended)",4,-1);
 
		UpdateTimeline();
		}
	}	
}
