DrumGizmo is an open source, multichannel, multilayered, cross-platform drum plugin and stand-alone application. It enables you to compose drums in midi and mix them with a multichannel approach. It is comparable to that of mixing a real drumkit that has been recorded with a multimic setup.
Features include:
Stand-alone, Lv2 and VSTi versions available
Open drumkit file format, allowing the community to create their own drumkits
Drum velocity, allowing for several different hit velocities for each drum
Multichannel output, making it possible to mix it just the way you would a real drumkit
Optional built-in humanizer, analyzing the midi notes, adjusting velocities on-the-fly
Stand-alone midi renderer, generating .wav files, 1 for each channel
Stand-alone midi input, making it possible to use DrumGizmo as a software sampler for an electronic drumkit
