midi problem

[base99]

hi,
I have strange thing with the ndlr which I don't understand.
Maybe anyone can give me a hint in which direction my problem is located?

problem:
I am using the ndlr with a miditech pianobox (GM-MIDI soundbox) pro via midi port a. the midibox has a big poti to change the different instruments. 
When the ndlr is playing I can't change the instruments with the big poti. I can turn the poti and I see in the display of the pianobox that the instrument
changed but the sound is remaining the same.
when the ndlr is stopped it is the same. the pianobox is blocked in some way.
If I switch the midi cable from the ndlr to endorphines ground control then I can switch the instruments on the pianobox during the play.

I don't understand what can cause this problem?
I have checked the ndlr manual but I don't find anything suitable.

any ideas?

Thanks,

Hi,
This is a strange one. As I've never seen the MIDItech Pianobox, I'm at a loss as to what would be causing it to be stuck on one instrument when receiving MIDI from the NDLR. I took a cursory look at the manual and nothing stands out to me as being the culprit, have you reached out to the company to ask if they know what might cause that issue? If you're seeing that issue it's likely been seen before. I didn't see a company email, but they do have a link to their Facebook page on the site.
Best,
Jesse
