PC (LSB, MSB) to Peak

I’m trying to send Program changes from my Hapax to my Novation Peak to change patches per pattern. The Peak has patches arranged by banks so I assume this can be done. However, when I set PC - for example “PC1, LSB 1, MSB 2”, nothing happens.
The Peak is receiving midi clock and midi start/stop but setting PC has no effect.
Has anybody encountered this or similar?

You have to trigger the pattern to make it send

Yes! It worked! Thanks for the reply!
