Reading this thread I don't think anyone is really saying Myth is a sampler or is trying to be a sampler
Myth however needs to load samples for the Iris Oscillators work. Without a sample there is nothing to resynthesize so there is no Iris
When people like yourself feel the need to play the hero and rant about how Myth is not a sampler all you are doing is mudding the waters
Is MYTH a Sampler? Of course not as it can't record samples. Does myth need samples? Absolutely the answer is yes
Page 13 of the user manual states "Drag and drop your own
samples onto the IRIS"
Then states
"The IRIS is a representation of
a sound source as a loop.
The start and end of the sample
are at the12 o'clock position."
Page 15 then states
"When you drop audio onto the IRIS,
machine learning is used to re-synthesize
The sample in a special way."
And
"MYTH approximates your sample by
finding the optimal combination of four
"
I could go on but you can read the manual for yourself
Myth 100% needs samples, it's what the synth is built upon, it's sample based to say it's not is silly
