HP 137 MIDI Transmit Channel

[simoncooldude]

Hey guys, wonder if anyone can help?

I recently purchased a JV1010 sound module to accompany my existing HP137 digital piano. Plugged the sound module into the piano and used the piano as the controller, works brilliantly!

Only problem is, I'm not trying to connect the sound module AND the piano to the PC via a USB Midi Interface. However, i need to change the MIDI Transmit channel on the piano... does anyone know how I'd go about that?

Unfortunately I have no manual so that option is out of the window. Thanks for your help
