Ambika--program change causes freeze when MIDI Out cable is connected

When a MIDI out cable is connected and I try to scroll through programs, the unit freezes. When I remove the MIDI out cable, unit goes back to normal.

My MIDI monitor shows the following:

13:48:07.665 From USB Uno MIDI Interface Program 1 65
13:48:07.710 From USB Uno MIDI Interface Control 1 32 0
13:48:07.711 From USB Uno MIDI Interface Program 1 65
13:48:07.756 From USB Uno MIDI Interface Control 1 32 0
13:48:07.756 From USB Uno MIDI Interface Program 1 65
13:48:07.801 From USB Uno MIDI Interface Control 1 32 0
13:48:07.802 From USB Uno MIDI Interface Program 1 65
13:48:07.847 From USB Uno MIDI Interface Control 1 32 0
13:48:07.848 From USB Uno MIDI Interface Program 1 65

13:48:07.984 From USB Uno MIDI Interface Control 1 32 0
13:48:07.985 From USB Uno MIDI Interface Program 1 65
13:48:08.030 From USB Uno MIDI Interface Control 1 32 0
13:48:08.031 From USB Uno MIDI Interface Program 1 65
13:48:08.076 From USB Uno MIDI Interface Control 1 32 0

…and it keeps on going like this ad infinitum until I remove the MIDI out cable.

I tried a couple different MIDI interfaces but that does’t seem to be the problem.

Routing on the computer seems to be correct.

I am new to Ambika so maybe I am overlooking something? I have not changed any MIDI settings on the unit.

I assume you have the MIDI out of Ambika to the MIDI in of your computer, and the MIDI out of your computer to the MIDI in of Ambika.

You shouldn’t do that.

Or if you really need to do it for some reason, change the Ambika MIDI settings so that it filters the program changes messages, or so that it doesn’t echo on the MIDI out everything it receives…

Right I have the MIDI in and out going to my computer. Ok I think I’ve got it. I changed the MIDI output preference to “controller”. Now my DAW receives the knob movements from the Ambika, which is what I wanted. Thanks for your response.
