[Media_api] (portmidi) recieved Sysex msg cutt-off

[Paul Dean]

I have a thread polling the midi input for data.  It set to store Sysex 
messages to a Byte array.   The problem is my Received Sysex messages get 
cut off at byte 76.





void process_midi(PtTimestamp timestamp, LPVOID pParam )

{

      int data = 0;



      if (inputFlag){

            result = Pm_Poll(midi);

            if (result) {

                  if (Pm_Read(midi, &buffer2, 1) == 
pmBufferOverflow){AfxMessageBox((L"Buffer Overflow")); return; }

                  // unless there was overflow, we should have a message now



                  //lets just simpily pop up a message box for each byte 
received.



                  CString temp;

                  data = (buffer2.message & 0xff);       temp.Format(L"%x", 
data);      AfxMessageBox(temp);

                  data = (buffer2.message >> 8 & 0xff);  temp.Format(L"%x", 
data);      AfxMessageBox(temp);

                  data = (buffer2.message >> 16 & 0xff); temp.Format(L"%x", 
data);      AfxMessageBox(temp);

                  data = (buffer2.message >> 24 & 0xff); temp.Format(L"%x", 
data);      AfxMessageBox(temp);

            }

      }

}







I’m sending this…

Everything comes in perfect until I get to Byte 76 and the rest is cutt off. 
   (no more data).

I’ve tried increasing the input device buffer..  no effect..   0 works the 
same as 9999   …

Any Ideas ?
