Sample sound different when triggering from GAse5

Hello
inspired by a YT video from Cubase- channel I want to rebuild the shown once. You always learn something new - and sometimes there are peculiarities that require explanation and a solution.
In this case it concerns the GASe5. In the empty kit, a sample is drawn from the Mediabay and a library (a tom sample) on an empty pad. However, when the sample is played, there are noticeable differences in the sound. The sample played from the MB (or from the track) is much more voluminous than when I trigger it from the pad. Here it sounds “flatter”. I can’t really understand that. And it doesn’t affect all samples.
Does anyone know an explanation?

Did you try to match the volumes of both carefully? By far the most crucial thing when comparing sounds.

I will test it - and perhaps i can upload a soundfile if it not works
