MDrummer comes with a huge library of samples, multisamples, rhythms, drumsets, loops and other resources. These are distributed via the MDrummer packs below.
Please download them manually and put them in some public folder on your computer. MDrummer will let you install them when opened for the first time. If you already have MDrummer factory data installed and want to install an additional pack, just download it and select Menu / Install pack in MDrummer.
If you are upgrading from a version prior to V12, please follow the instructions in the release notes.
