Big MPD 32 probleme in Ableton

Hello people,
I have the following problem.
Once I was in Ableton e.g. advices with a bass line, playing a piano that I played once at some point. Even if I create a new project and put down the volume in the bass line plays the piano as soon as I hit a pad.
I hope you can help me. Thank you

No. idea. what. you. mean.

So I think I can not describe accurately enough. But can anyone say how i programmed the MPD 32 newly, so dead and make reinstall ?

As I understand, you just wanna reset your akai to factory settings.
On your AKAI:

Pressing ENTER at step 5 below will erase ALL MPD32 presets and reload the Factory Presets that shipped with the unit!

1. Press [>] - this will open the SAVE screen.
2. Press [>] again - This will open the PRESET NAME screen.
3. Press [>] to move past each letter in the current program's name, until the last character is reached.
4. Press [>] one more time - The FACTORY will be displayed.
5. Press [ENTER] to restore the factory defaults to your MPD32.
