GhostSmack helps you create velocity-layered drum kits for Koala Sampler. Upload multiple hits of the same drum at different intensities, and GhostSmack will sort them from softest (ghost notes) to loudest and optimize the compound sample for Chopper — giving you expressive, dynamic control over your drums.

Perfect for snares, kicks, hi-hats, or any percussive sound.

This service is free and made for the community. By uploading your sounds you allow ChopMill to consider output files based on your source material to be a part of freely available compilation/packs. No money will be made from your sample.

Sequence/Record: Upload or directly record a single audio file containing multiple notes played in any pitch and sequence. PitchMap will automatically choose its best suited algorithm to recognize your takes. Leave around 3 seconds of silence (the best you can do) at the start and end of your take and between notes.

ZIP File: Upload an archive of single shots. If they have note or MIDI values in their name, PitchMap will take these as the ground truth and build your output files based on that.

Give your instrument a custom name. This will be used in the output filename, making it easy to identify your samples later. Leave blank for an auto-generated name based on your settings.
