SynthScaper is a synthesizer designed for those who want to experiment with creating ambient soundscapes. It allows users to explore a wide range of sounds, from noise to melodic instruments and everything in between.

What sets SynthScaper apart is its unique sound engine. You can use multiple built-in or downloaded samples to create beautiful melodic pads or intriguing atonal soundscapes. This is possible through the use of multi-layered oscillators, chains of filters, and effects. The app also features envelope generators and low frequency oscillators to help shape your sound further. You have the option to create your own sound scenes by combining various oscillator presets from the built-in library or you can simply use predefined scenes.

The flexible settings of each module in SynthScaper offer great opportunities to craft unique and colorful sounds. You can transform standard instruments or natural samples into something truly special by adding automated changes and spatial effects for endless variations. The app allows for advanced control of sound through different ways to assign both screen and MIDI keyboards to the oscillators. The on-screen keyboard is specifically designed to help you create continuous textures and drones while also enabling various special effects.

A standout feature of SynthScaper is the Designer tool, which uses a neural network to generate new presets. It takes existing sounds, adds random variations, and ensures that new presets are similar to the selected pattern. This feature makes it easy to explore new sounds without starting from scratch.

Here are some key features of SynthScaper:

You will find three independent oscillators, each with three layers. Each layer can have up to six voices for a rich sound. There are also six envelope generators and six low frequency oscillators available. Each oscillator includes an arpeggiator and sequencer. Additionally, you can utilize the Designer tool to generate new scenes and presets.

For effects processing, you will have general controls for level, balance, low-pass and high-pass filters for each layer. There are three slots available for filters and effects after each oscillator, along with twenty additional selectable filters and effects. The spatial mixer gives you access to two different sound spaces, allowing for immersive audio experiences.

The screen keyboard comes with features adapted for continuous textures and soundscapes. There are predefined keyboard scales, as well as options for creating custom scales. The keyboard can be used in full screen, double, or split modes, and you have choices for pitch, continuous modify, and velocity settings. SynthScaper supports two virtual and two MIDI keyboards simultaneously, with flexible keyboard assignments to control the oscillators.

You can easily upload samples through Dropbox, web access, or clipboard. The app allows for both auto and manual tuning of samples with a frequency analyzer. You will find a set of predefined and ready-to-use scenes and presets in the built-in sample library, which contains various instruments, synths, and noises. There’s also the ability to pack and share scenes and samples as a single file.

SynthScaper supports loop points and note information in WAV files, making it easy to work with your favorite samples. It is compatible with Inter-App audio, providing transport and BPM controls. Additionally, it supports Audiobus 3 with state saving features and Ableton Link, allowing for start/stop synchronization.

To run SynthScaper smoothly, it is recommended to use at least an iPhone 6, iPad Mini 4, or iPad Air 2 or newer.

Overall, SynthScaper is an incredible audio design tool. It empowers users to dive into unique sonic creations. Whether you're looking to craft ambient soundscapes or experiment with intricate melodic patterns, SynthScaper offers the tools you need to bring your ideas to life.
