MPE pitchbend in M4L

The patch is suppose to generate a midi note and this part that I am attaching is suppose to alter the note with pitchbend. Since the notes that I am generating have different sustains I want to bend the pitch individually, which would need MPE. I got this working with Xfer Serum, but it won't work with other synths in Live (Wavetable, Opereator, etc) and Serum2. I don't know whats the problem. I want some help.
