Key Features
- Complex Oscillators: Asper provides one wavetable oscillator with an extensive collection of 118 wavetables. This oscillator is divided into two layers, each featuring independent controls such as Comb Filter and Detune, allowing for precise sound shaping.
- Versatile Layering: Users can blend the two oscillator layers in various ways and apply phase distortion with five distinct shapes for added creativity.
- Noise Oscillator: In addition to the wavetable layers, Asper includes a noise oscillator to expand your sound palette.
- Humanized Sound: The synth incorporates Round Robin simulation for both the wavetable and noise oscillators, introducing an organic and imperfect quality to the sound, mimicking real-world instruments.
- Comprehensive Feature Set: Asper offers an impressive set of tools, including a two-mode Shaper, Vibrato module, Portamento with adjustable velocity triggering, Ensemble module, Mod section, and a versatile Filter with Parallel and Serial modes.
- User-Friendly Interface: Despite its depth of features, Asper remains easy to navigate, ensuring accessibility and ease of adjustment.
- Abundant Presets: The synth includes a wealth of presets through a simple preset manager, making it an ideal choice for sound designers and musicians.
- Resizable GUI: Customize your workspace with the GUI, which can be resized from 80% to 150% for optimal viewing.
