AKSampler is not a full SFZ player. It supports only a very limited subset of the SFZ format, as described here:
https://github.com/AudioKit/AudioKit/blob/v4.2/Documentation/PreparingSampleSets.md
from romplayer.

I used Wavepack to convert all wav files to wv. But still no sound. Any specs to tell what kind of samples can be played in ROMPlayer? Thanks.
I move the samples to original samples folder and modifed my .sfz file like original .sfz. It works. So that means the samples has no problem at all. The problem is from the .sfz itself. Why?
This is my original sfz:

It doesn't work. The modified one:

The problem is from the .sfz itself. Why?
Please read my original reply above, where I said "AKSampler is not a full SFZ player" and gave a link to the exact format. That is "why".
Also, note you don't have to convert .wav to .wv. That's just a way to reduce app download size. If you get the ".sfz" format correct, you can use .wav files, or .aif files, etc.
