difference between P-chain on Pad

[racecube]

I would expect it to be the same if I have a Pad sound on 1 Channel or if I have a Pad sound on 3 channels chained in the global settings (of course Synth sound on all three channels exactly the same), but it isn´t not even in the harmonies. I´ve read through the manual and have no explanation for that behaviour.

Can you confirm that a chain on three channels with the exact same sound is the same as play it on one channel in case of harmonies?

I believe the expected result is just a round robin selection of each note sent, with each consecutive note going to a different output. I don't know if they're treated as monophonic or not, but if that is the case that could explain the difference, since only 3 notes would sound. I'll ask Steve if he can explain that for me.
