multi-core dsp effect not working on Reference release 16.6

[insession]

I have dBpoweramp Reference R16.6 (Single PC), multi-core dsp effect does not work. Only encodes with one core, I then manually have to check all 12 cores while it encodes, then it uses all 12 cores. Any help? Thanks!

It is likely the DSP effect multi-core CPU Force was introduced after R16

PS do not post your order number to the forum, others could take it over.
