Building Sample-patches of Instruments in drum and synth

Hey everyone,

At the moment I‘m creating samples from old key-Instruments like Piano, e-Pianos, Mellotron etc. When I sample in synth I find the sampled key quickly comes out too squeezed in the high keys or with too much artefacts in the lows compared to the original. Therefore I find sampling every third key inbetween two octaves within the 12s limit appears most natural. Later cut and pitch them on every single key on OP1 or the drum utility.

What’s your approaches in this situation☺️?
