Soundfonts ideally map each key to an individual sample.
Otherwise (e.g. for size/efficiency/laziness) whole key ranges are
mapped to one sample. Non-root keys will be "interpolated" so to speak.

In case I do still have the opportunity - how should I 'lay out' my samples to key ranges?

Let's say I'm sitting here with a strange rare instrument having one hour studio time.

Probably someone is going to reply "if it sounds good, you are good"
but I'm interested in general advice here - and you just get one try with a Stradivari ;)

Just to detail my (made up) use case:

Let's say the instrument can produce pitches in 3 ocatves, e.g: c2 to c5.
My gut feeling is: sampling just six notes should be good enough?.
I'd then go for the extreme ones c2 and c5, plus maybe c3 g3 c4 and g4.
Or not?

Il also I wonder if my ranges should "favour" downsampling where possible, instead of
having root keys in the middle of a range (as many downsampled keys as upsampled ones)

PS: Polyphone is a great piece of software!

The scenario that you've described is 'sampling in fifths'. If you only had one hour with an instrument, I would recommend you to sample in thirds or per key.

You can sample in many ways:

In octaves - Low quality, most compact
In fifths (C, F# or G) - Medium quality, fairly compact
In thirds (C, Eb, F#, A) - High quality, fairly large
Per key (All keys) - Highest quality, largest

You should select the one that you want.

When you sample acoustic instruments, don't favour downsampling. You would not get the most natural sound, as if you have samples in thirds, putting root keys in the middle will result in interpolation of no more than one semitone, resulting in a better sound. However, for synthetic sounds, downsampling has less of a negative effect on sound quality.

I'd better put the actual root key in the middle of the corresponding range.
Convinced.

Btw I only now re-realize how little I know about filter design, Nyquist frequencies and whatnot
- but that's another story altogether.
