@Machli-Achilles Does it help if you set the BPM of your project to the BPM of the loops before you load them into Music Maker?

I also think you can get much more out of your loops, if you use a sampler VST (you need the VST feature from the in-app-store installed for this to work), for example Big Fish Audio Momentum, which is free. https://www.bigfishaudio.com/momentum.html This VST is made especially to play loop packs with your keyboard. Check out the tutorial videos. It will also adapt loops to your BPM and key of the song.
