[SOLVED] Why isn't this call to SetMediaTrackInfo_Value setting the Source Channel?

Hi,

Going crazy trying to figure this out.

I am trying to set a track's send source channel as below:

Code:

reaper.SetMediaTrackInfo_Value(sendtck, "I_NCHAN", numchans+2)
reaper.CreateTrackSend(sendtck, rectck)
send=reaper.GetTrackNumSends(sendtck, 0 )
rval = reaper.BR_GetSetTrackSendInfo(sendtck, -1, send, "I_SRCCHAN", true, numchans)

where sendtck and rectck are tracks that I previously obtaind via reper.GetTrack and numchans is, say 4.

No matter what I do, the source channel remains 1/2. The sending track indeed has correct number of channels via the SetMediaTrackInfo_Value call. So basically, everything is working except the source channel just doesn't want to cooperate...

Ideas?

thanks!

In line 3 you get the current number of sends, which you use in line 4 as send index (the send variable), but send index in BR_GetSetTrackSendInfo is zero based (according to doc), so shouldn't it be?

Code:

rval = reaper.BR_GetSetTrackSendInfo(sendtck, -1, send-1, "I_SRCCHAN", true, numchans)

Ok, it was because I wasn't using 0 as the identifier for a track send (versus -1 which is for track receive)

this is how it is working now:

Code:

reaper.SetMediaTrackInfo_Value(sendtck, "I_NCHAN", numchans+2)
reaper.CreateTrackSend(sendtck, rectck)
reaper.SetTrackSendInfo_Value(sendtck, 0, send, "I_SRCCHAN", numchans)
