The drum has certain similarities to the Hang Drum, but is more clean, less “steel-drummy”, has more harmonics and overtones. We recorded Propanium in a variety of ways including finger, brushes, mallet articulations and tons of effects. The drum follows our “deep-sampling” methodology and the larger patches generally have approx. 10 velocity layers and 6-8 round robin (repetition) pr. layer, however certain patches (ex. overtone patches) have over 35 velocity layers for maximum playability.
