Maximum sample size Polyend Synth

I’ve read the manual a few times but am I missing something? As we have to edit the samples before transfering to the DWA folder etc, fine… but is there a time or sample size limit to importing samples to the the DWA folder.. et al?

I ask because some samples of drum loops (over 2mb or 8 seconds) dont register in the file, but some vocal loops beyond this do.. :face_without_mouth:

I understand the format, mono etc. I get each folder has a sample limit of 250 odd samples, but if someone could shine a light on the individual sample length in each folder that would really help.
Thank you, much love…
