I recently bought an ADA Tribtube 75 and then just rec'd an ADA MPC  Midi Controller off eBay which I rec'd today.   I connected the MPC to the amp using a 7 pin phantom power midi cable.  Unfortunately, the  display isn't working correctly.  It says ADA then starts blinking but when I step on various number switches it never settles on a number

I made a short 1 minute video of what the display does when powered up.

Any idea what is causing this issue - is it a power supply problem or an MPC issue?

I have not tried a power supply yet....  Can a typical Boss PSA 120 9 volt adapter work or does the MPC have the opposite polarity on it's 9 volt adapters?

Thanks for your help
