From what has been shown off so far, there seems to be no way to tune the samples in the new sample mode. If I'm correct, please consider adding that option. Since sample selection is a shift function on one of the encoders, it would make sense to put key center and tuning (±50 cents) on the other orange knobs as shift functions. Otherwise bass samples (which might not even be C) would be stuck in the middle of the range and out of key.
Of course, maybe you already thought of this and none of the YouTube videos I saw covered it.
