When sampling an instrument for tonal music, use the 'cycle of fifths': F, C, G, D, A, E, B, etc. But, as explained above, this assumes the ability to multi-sample...
See this rather complete article on piano sampling: https://audient.com/tutorial/pianosample/
For the rest (e.g. atonal percussion, concrete or experimental music), there is no rule.
But, in a modular, filters, wavefolders, envelopes and vcas, will be very useful :))
