Synthesizer specially designed for creating and experiments with ambient soundscapes in wide range from noises to melodic instruments and everything in between.

The sound engine of SynthScaper has its own unique sounding differ from any other software synths. You can construct outstanding melodic pads or atonal soundscapes from different kind of built-in or downloaded samples by using all power of multi-layered oscillators, chains of filters and effects, envelope generators and low frequency oscillators. Or you can create your own sound scenes combining oscillators presets from build-in library. Or just use predefined scenes.

Very flexible settings of each module give you a great opportunity for creating unique and colorful sounding from usual instruments or natural samples and adding automated changes and spatial effects for an endless variations. Different ways of assigning screen and MIDI keyboards to the oscillators provide very advanced features to control the sound. The on-screen keyboard is adapted to create special effects and varying the continuous textures and drones.

The Designer tool uses the neural network to generates new presets based on already existing by adding some random variations and checking the result so that the new preset remains similar to the selected pattern.
