Assuming by samples you mean the constituent parts of each soundpool (not the actual instruments) you have as part of MM, then, unless you have bought the appropriate commercial licence for each individual soundpool you use then, Yes you will! Please read this forum sticky and full details about the different types of Magix licence here.
Hi! Does Magix music maker 22 esd or Music Maker 2022 Plus Edition support third-party synthesizers and VSTs? If not, which one is it and how stably does it work?
The official Magix page for comparing the different editions of Music Maker is here.
MM Premium, and, I believe MM Plus, allows for external VSTs and VSTis; lesser editions do not, without the purchase of the "Additional Tracks and Features" add-on.
