Code 25 goes into test mode when connected to Logic


Today I connected my Code 25 to my MacBook Pro to record in Logic Pro X but when I connected it, it went into TEST MODE (which I've never seen before) and I could not record any output from the amp.  I unplugged, and restarted both the computer and the amp - same thing happened.

I had my phone hooked up by Bluetooth to control the settings, but I've done this many times in the past and never had this problem.  Ideas?  Solutions?

The problem as I initially stated it is still a problem; however, I was able to bypass the issue by connecting the headphone jack through an Edirol USB audio interface into my computer and I could record directly from the amp. I do want to say, however, the manual DOES SAY that you can connect from the USB output to a computer. That still does not work. - Hershey Bell 22 Dec 2018 at 12:29 AM

Hi Hershey,

Thank you for your message, do you have any MIDI utilities that they are running on you Mac, or have any Logic Pro X SysEx faders set up, that could be broadcasting a message to the amp.

You could also try to see if there are SysEx messages being sent out.

I don't believe so, but let me try that website and let you know what I found out.
