Sample purge not affecting free memory

I recently started working with longer / bigger sample files on the 301, and while I am aware of the memory limitations, whenever I try to “purge unused samples”, they get removed from the pool but the available memory doesn’t grow back :frowning: I am preparing my 48khz .wav files with Ocenaudio on my m1 macbook either in 24 or 32 bit. Am I doing something wrong? the 301 is running on v.0.7.0

(haven’t checked yet if the same happens with smaller buffers/samples)
