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. http://youtu.be/OH55M1tYuuk
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
