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. Key features: - Three independent oscillators. - Three layers for each oscillator. - Six voices for each layer. - Six envelope generators. - Six low frequency oscillators. - Arpeggiator / sequencer for each oscillator. - Designer tool for generate scenes and presets. - General processing of level, balance, LPF, HPF for each layer. - Three slots for filters and effects after each oscillator. - Twenty additional selectable filters and effects. - Spatial mixer with two different sound space. - Screen keyboard adapted for continuous textures and soundscapes. - Predefined set of keyboard scales and custom scales. - Full screen, double and split features for screen keyboard. - Options of screen keyboard for pitch, continuous, modify, velocity. - Supports for two virtual and two MIDI keyboards at the same time. - Flexible assigning keyboards and controls to the oscillators. - Two main effects controls can combine several parameters. - Uploading samples thru Dropbox, Web access, clipboard. - Auto and manual tuning of samples with frequency analyzer. - Set of predefined and ready-to-use scenes and presets. - Built-in library of samples of instruments, synths, noises, etc. - Possibility to pack and share scenes and samples as single file. - Supports loop points and note info in WAV files. - Detailed application description (built-in and PDF file). - Inter-App audio compatible (with transport and BPM controls). - Supports Audiobus 3 with "State Saving" and MIDI features. - Supports Ableton Link with start / stop sync. Requirements: Recommended at least iPhone 6 / iPad Mini 4 / iPad Air 2 and higher.

Tera Pro brings together all major sound synthesis methods on one table. No matter if you want to recreate sounds from analogue legends or explore modern digital sounds with FM, Waveshaping or Wavetable synthesis. More can be added by In-App Purchases of new modules. Add some flavour of physical modelling and modules for additive synthesis. Combine them altogether for new sound experiences far beyond your wildest dreams. Tame this overwhelming amount of possibilities with Tera Pros intelligent user interface showing you only exactly what you need, paired with realtime oscilloscopes and level indicators helping you seeing what’s going on. Connect the modules with a flexible routing method without the visual cluttering of real wire cables needed in conventional modular synthesisers FAQ What does Tera Pro have that Tera Synth doesn't have ? 1) Additional Sound Modules - Spectrum oscillator ( borrowed from the heart of Addictive Synth ) - Wave shaper / folder opens the west coast synthesis - Vocal Morphing filter - KARPLUS (aka WaveGuide ) with new "Swarm" mode ( 3 detuned delays ) 2) Revised engine - Analog Polysynth Voice Modelling with characteristic subtle voice variations of timbre, pitch and temporal behaviour to get you "The" Analog Sound. - 128 vs 32 voices polyphony - Seamless Sound Switching: change presets during play without cutting off the sound. - 8 times unison for really heavy ambients - Envelope generators with Buchla style "end of cycle" trigger for generative music - Stack/Split Sounds - New effect section 3) Redesigned User Interface - Collapsible modules for clear view of modular structure - No more nasty popups for LFOs/Envelope generators - Realtime oscilloscopes added to selected modules 4) New Presets - About 1000 additional presets in there.
