Yes, all our sample packs are royalty free!
You are free to use the samples, presets etc. in the context of your own, original musical compositions. Your song cannot be a copy of the demo song from the sample pack and if you are using a complete construction kit, you will need to rearrange and add a portion of your own material for the song to be considered original composition. You are free to release and sell your songs containing samples commercially.
You are not allowed to use the sounds in multimedia such as applications, software or any kind of interactive media where sounds would be integral part of the products distributed to general public. This type of use requires a special content license. Releasing, re-selling or re-distributing the samples in isolation (as they are sold) is also not permitted.
