Hello Henni

Not sure if I understand you correctly but let me start by saying I have never ever worked with EMC or similar program.
Do I understand correctly that you want to extract the factory styles from the PA50 so that you can process them with this conversion program ?
If so the solution should not be too difficult because on any Korg PA arranger you can switch off the "factory style protect" ( somewhere in Utilities, page 7 I believe) and then you can save either a bank, or a single style onto SD card or USB, and take it from there.
If your question means different please enlighten me/us !!

best wishes,
John
