Disabling external control of internal samples

I use my MPC both as a drum machine and as a midi sequencer for my Moog. The problem is, the MPC assigns its internal drum samples to the keys on the Moog, so when I play a note on the Moog I hear a drum noise from the MPC. I know I can turn off the program for a specific track, but is there a way of disabling all external control for the samples store on the MPC, and isolating the pads as the only control for samples?

No.
But maybe the "active track receive channel" setting can help you.

which os?
I think it was possible without workarounds before os2xl

I think that has been discussed before. Turns out to be an XL only issue

yep otherwise you have to turn pad to internal sound OFF in midi mode.

Try setting the Keyboard to another midi-chanel and use the "Active track recive chanel" setting (Mode + Midi/Synch) and select a specified chanel, not "All".
That works well for me, but it's allways a bit thinking wich chanel to select
