Proper way to sample and use an instrument with ER-301 - 12tet

HI, newbie here.
What’s the best way to sample an instrument and play it chromatically in er-301? How many notes need to be sampled so the 12tet works correctly I’ve tried to sample 48, considering it a multiple but for some reason doesn’t seem to stick to a scale, considering a CV quantised to the scale on the way in.

Thanks

The number of samples shouldn’t matter. There is no wrapping logic. The samples just need to be consecutive on the chromatic scale.

Instead, I would look for the problem elsewhere. For example, this catches a lot of people off guard:
