Geonkick is a percussion synthesizer for building drum sounds from oscillators, samples and noise rather than relying entirely on prerecorded drum kits. It gives producers precise control over the transient, pitch movement and body of sounds such as kicks, snares, claps, hi-hats and shakers.
An instrument is generated from its current synthesis settings and retained in a playback buffer until the sound is edited again. This approach makes the software responsive when triggering instruments while allowing extensive experimentation during editing.
Individual percussion sounds can be organised into kits, assigned to MIDI notes and routed to separate outputs for subsequent mixing.
This is free and open source software.
Key Features
- Kits containing up to 16 percussion instruments with configurable MIDI note mappings.
- Three synthesis layers per instrument with an independent layer mixer.
- Three oscillators per layer offering standard waveforms, noise and sample playback.
- Frequency modulation between oscillators for complex transients.
- Amplitude, pitch, noise-density and filter envelopes.
- Low-pass, band-pass and high-pass filtering with resonance control.
- Multiple distortion curves, limiting and other dynamics processing.
- Individual instrument tuning and velocity-sensitive output.
- Configurable multichannel routing for mixing drum-kit components.
- Kit save and load functions, plus SFZ kit export.
- Export of percussion sounds to common audio formats.
- Standalone use and LV2 instrument plugin operation.
