Hello one and all

I was checking the behaviour of my Korg nanoPAD2 (which I've been having a lot of 'fun' with all afternoon, now resolved hopefully) and noticed in the MIDI Monitor window that Studio One seems to be continuously sending Note On messages to it, as follows:

Message:
91 00 64

Description:
NoteOn C -2

Ch:
2

Port:
[OUT] FaderPort

I don't think that I've seen this before, but then again my memory is not perfect. Is this normal/usual behaviour? Some kind of 'keep-alive' message perhaps? The Faderport does seem to be working as expected, it's just a little annoying that it fills up the MIDI Monitor window with all these messages. It seems that this is Studio One, rather than the Faderport, that it doing this.

Thanks
