 To conduct the experiments, we use the implementation of the new sampling algorithm in DrumGizmo.
 As a base-line for comparison, we use the previous sample selection algorithm of DrumGizmo.
 We want to evaluate how the sample selection algorithm performs in practice, therefore we use the drum kits of DrumGizmo. In particular, we use the power value distribution of the samples of those kits.
-We do experiments on three different drum kits. See Table \ref{tab:drumkit_data} for some information about the samples of the drum kits and see Figure \ref{fig:power_level_distribution} for a visualization of the power level distribution of the kits.
