@eric-gaertner If you just want to create stems and don't use ACID as a software to make music I would suggest you return ACID by contacting sales support at infoservice@magix.net and get the free, pretty good SpleeterGUI (much better results than Stem Maker) mentioned in the topic that was linked by @PATIENT-X or you buy RipX DeepRemix https://hitnmix.com/remix-software/ which has by far the best, cleanest stem separation I have encountered so far. It is even better than the much more expensive iZotope RX stem separation which is already very good. DeepRemix is an affordable one time purchase, no subscription and works without an online service in the background. But you need a modern NVidia graphics card (it also works without it, but much slower) and a lot of RAM.
