SP16 midi program Change

Hi

I can set a program change, no problem. But i cannot make it to send it automatically. When i program bank select and PC the sound on my synth is changing: Good. i run my sequence. let's say i change my synth patch on my synth, i would thought that when i restart the sequence on the toraiz the program change will be sent again: No. i have to reselect it even if it's still programmed. Toraiz should send the program change upon starting the sequence. i tried to program it on a step, does not work. any ideas?

thanx
