For all of my drum packs I use “GM Mapping” to make everything as cross-compatible as possible. However, nothing is perfect and there are a couple of tweaks you may need to make to get everything working correctly. This is as a result of there being slight variations between the various “GM Mapping” presets across the GGD sample libraries, as well as certain packs having access to different cymbals and numbers of toms. Click your GGD library below, and I will explain how to match your MIDI map to each pack!
