They are excellent for elements and particular parts. They are a mix of real / synth based instruments and drum/percussion loops. Good deal, especially when they are on sale. I hope there will be a other release within 2022.
Stefan, I use mainly percussive loops. Some instrumental loops will follow chord changes if they Acidized, some will not (which are not Acidized). A lot of modern and ethnic percussion/drum loops in those packages that are very usable. These will follow tempo and "mutes at the bar" Loops were skipped this year, so I hope we will see 3rd pack sometime soon
The +++ Bandlab Sounds +++ website has more than 15,000 loops available for download. Best of all, they are FREE. However you do need to provide an email address to create an account.
