Aevium: Bird-Sound Synth Library for Kontakt by Soundiron

Soundiron built Aevium from a wide range of raw bird recordings, then warped, stretched, glitched and overdrove them into playable instruments. The developer describes the set as a mix of fierce lead synths and atmospheric pads.

The library includes 1,810 stereo 24-bit, 48 kHz WAV samples spread across more than 400 factory presets. Categories cover classic punchy leads, warm pads, dark drones, bubbling atmospherics and other textures, so the library can cover both melodic and ambient parts.

The interface is built around four layers, each with its own Attack, Release, Offset, Pitch and Pan controls. Every layer has an individual filter with 39 filter types, and modulators include LFO, ADSR and Velocity. Targets include volume, pitch, pan, filter frequency and filter resonance.

The central XY Pad defaults to volume control between the four layers, but each axis can be reassigned to other parameters or some FX. You can add tempo-synced rhythmic motion to the pad and limit its range to create new patterns in tone. A morphing engine and randomize function support fast exploration, and custom presets can be saved, shared, imported and exported.
