Two high quality drumkits for DrumGizmo


Through a collaboration with Michael Oswald, Libre Music Production are proud to present two high quality open source drumkits
for DrumGizmo.

Michael has written a tool (DGPatchMaker) in the programming language Haskell to create DrumGizmo drum kits from existing sample libraries, and using that, he has created patches for the free SM Mega Reaper Drumkit and the Salamander kit.

For creating DrumGizmo drumkits from existing samples by hand, there is also a blog entry by Michael. The tool is designed to help with utility functions on repetitive tasks (some libraries contain up to 10 000 samples) and does also various checks to keep the patch consistent.

If there are requests for it, the tool can also be open-sourced, though it is currently a (just-working-good-enough) prototype implementation.

Download the SM MegaReapter Kit and the Salamander Kit.

Download the kits for DrumGizmo including instructions (SM Megareapter Kit and Salamander Kit). In the archive you will find a DRUMGIZMO folder, which just has to be copied into the root directory of the downloaded drumkit.

A video demonstrating the first version of the DGPatchMaker editor for DrumDrops drumkits, where the patch creation is done automatically. It is also possible (and for most sample libraries necessary) to do this manually by hand (this was needed for the two kits provided here) as each library has it's own sample structure.

Further free libraries to be envisaged for creation of DrumGizmo patches are the TChackPoum kits, so stay tuned.


The SM MegaReaper Kit link links to a wrong archive (only cymbal samples, stereo, completely different naming scheme). Michaels drumkit file needs older mono sample pack that can be found here

Thank you for reporting this! We have now corrected the link.

I've downloaded these, but for some reason just the kick drum sound comes out. All other instruments are silent. (Drumgizmo works fine with the MuldjordKit.) I think that the directory structure is fine. $ ls SalamanderDrumkit/ DRUMGIZMO/ ALL.sfz hihat.sfz kick.sfz REAMDE Salamander Drumgizmo Patch.odt SalamanderDrumkit_meta.xml OH/ crashesFX.sfz hitom.sfz lotom.sfz ride.sfz Salamander Drumgizmo Patch.pdf snare.sfz $ ls SM\ MegaReaper\ Drumkit/ DRUMGIZMO/ SM MegaReaper Drumgizmo Patch.odt SM MegaReaper Drumkit.RPP SM MegaReaper Drumkit_User Manual.pdf samples/ SM MegaReaper Drumgizmo Patch.pdf SM MegaReaper Drumkit.RPP-bak Any ideas?

Reply from Michael Oswald: Did you route the outputs correctly? Sounds like only output 1 and 2 of drumgizmo are connected, which in the case of the Salamander Kit is only KickL and KickR. The Muldjord kit has the Room microphones on channel 1 and 2, so you get the whole kit, but not the specific samples for the individual drums. At least this would explain, what you experience. As an example on how to do this an Ardour: There is also a LMP article about that:

Thanks for the reply. Indeed, it was a routing problem. I must have done something wrong the first time, as I was sure it was routed correctly, but when I started a new project from scratch and set the routing it all worked. So, I am sorry for the noise and thank you for the help and for the kits. They sound great!
