For the synth sample function, you upload a 6 second sample into the OP-1, a patch is created when the OP-1 boots up using the sample with the speed of the sample adjusted to create different notes.
i don't recall that being a thing w/ the sampler specifically. but i def could be wrong.
maybe u are thinking of the function that you can change synth engines on the fly and it keeps the same parameters that you selected from the previous synth.
i think that is shift T1? i haven't used this in awhile so apologies for my lack of concreteness
you can easily lift up a synth and drop it into the drum sampler.
