Lush pads, psychedelic synths and atmospheric soundscapes in an easy to use app with a powerful sound engine. SynthScaper LE has three independent sound generators in which you can use various presets from the large built-in library and create unique multi-timbral sound scenes. You can tune the general parameters that define the character of the sound of each generator and place them in a common sound space with the spatial mixer. The spatial mixer simulates two types of reverberating space in which you define the distance and position from the sound generator to the listener, the dimension of the space and amount of reflections. Use the "Random" option to get new ideas for your unique sound scenes. This option generates a new scene from existing presets and sets the generators' parameters to random values. Next you can adjust them to polish your special sound. The screen keyboard in addition to standard use has a special mode that turns it into a continuous area in which you can smoothly change the tone separately for each touch. This is ideal for creating a variety of soundscapes, drones and textures. The screen keyboard also has a simulation of velocity, adjustment of pitch and the rate of modulation, as well as a scale editor with a built-in list of scales. Each sound generator has its own sequencer / arpeggiator, so you can create a common sequence for all generators or separate sequences for each. Many different modes allow you to turn even the simplest sequence into a continuously varying melody changing just by pressing a single note. You can also record a sequence from the keyboard or copy it from other scenes. SynthScaper LE fully supports MIDI keyboards and controllers and can assign external MIDI controls to almost all parameters. You can assign sound generators to different ranges on your MIDI- and on-screen keyboard, and even only to MIDI or only to the screen keyboard. In addition, this app can auto detect the type of MIDI keyboard and automatically use extended controls such as knobs and buttons. For a list of supported MIDI keyboards and assigned controls see the app description. This app can work as standalone and can be used with any audio host or DAW apps that support AUv3 or Inter-App audio connection. SynthScaper LE is completely compatible with the full-featured advanced version SynthScaper and can import scenes packs created in the advanced version.

Evolver is a performance tool for creating multi-layered evolving sequences of sound. At its most basic think of evolver as a 4 lane sequencer which creates automatic accompaniment from notes and chords as you play on your MIDI keyboard, but it can also be used to create elastic evolving soundscapes where audio samples seamlessly merge into one another to create highly complex and original sounds. At the heart of evolver is a sophisticated wave synthesizer and sequencing engine which can create dramatic hard hitting transitions of sounds or merge sounds to create seamless transitions that evolve in time to the beat. It has 4 sequencer lanes which can run independently and mixed together using the real-time controls or over MIDI. When you play a chord on your MIDI keyboard for instance, each of the 4 sequencer lanes will take those MIDI notes and translate them into a musical sequence of sounds which are combined together and synced to create a form of automatic accompaniment. Evolver can load its own multi-layer patches or import them directly from Chameleon. These patches can be layered using the 4 sequencer lanes or split over a virtual keyboard. You can assign key zones, transpose them, assigned MIDI channels and velocity levels, set latch options etc. You can also load in your own one shot samples and lay them end on end to create evolving atmospheres or backing soundscapes. These samples can be looped or be free running with definable start/end and loop points using our non destructive editor. We also included a third sound source which lets you build sounds on the fly by overlaying harmonics to create anything from traditional sine, square, triangle, saw waves to complex detuned oscilators. These can be used in conjunction with multi-samples or one-shot-samples within the same sequencer lane. You can even randomize a complete sequence of harmonic sounds which when pieced together create some very unique and dynamic voices. Each sequencer lane can be up to 64 steps in length, each step has independent timing, pitch, volume, gate, probability, sample source etc. so the scope of what is achievable is vast. Each sequencer lane has its own ADSR, VCF and LFO which operates on all sounds within its lane, as well as being able to change the underlying settings for each sound source. Evolver also includes an ARP function which can be run in one of the default modes or you can define your own fingering patterns to be used to enhance your playing style. Create your own sequences, lay down your MIDI notes in your DAW and have Evolver automatically play along to your chord sequences, automatically locking to the host tempo. Sequencer events can be fixed or transposed allowing you to create percussive and drum backing using a single lane. Key Features: • 4 sequencer lanes • Up to 64 notes per sequence. • Each note can be fixed or transposed. • Timing and note probability. • 3 different sound source types (multi-sample, one-shot samples and harmonic) . • Add your own loops to a sequence. • Built in ARP function. • Import your own samples and mutli-sample patches. • Chameleon Support. • 5 different effect types (reverb, delay, phaser, flanger and chorus). • 8 band EQ. • .Latch Feature to hold chords/notes. • Create independent key zones with transposition and MIDI channels. • Paramter Automation from your DAW. • Control mixing and sequencer enable buttons using MIDI. • Built in Sampler. • Multiple Import options (including an experimental SFZ format). • iTunes and Files App importing of samples into the audio pool. • Files App Drag & Drop Support • Comprehensive Help pages included.
