Classic FX is a complete sound effects processor and a mono-to-stereo enhancer with equalizer, effects and reverb, based on specially designed high-quality processing algorithms and suitable for any kind of audio sources. This application will add brightness and expand the sound space of any musical instruments, synthesizers, drums or voice. Unique and diverse effects with unified control parameters provide convenience and ease of customization, while at the same time plenty of room for individual expression and experimentation. Another unique feature of Classic FX is the Morphing option, based on complex effects matrix transformations, which allows you to control the dynamic transition between any two presets. While this can produce stunning effects, it's a breeze to control - you just need to move a fader or push a button. For more morph experimentation, this app has three LFOs to create more complex waveforms for changing morphs. Each LFO has different ranges, waveforms and can sync to the external BPM. Some of the other features of Classic FX: - Classic FX has 22 unique processing algorithms and 40 different presets. - Two slots in which you can use different effects and smoothly morph between them. - Three band equalizer with high / low shelving filters and middle peaking filter. - Easy to use algorithmic reverb, suitable for any sound source. - Limiter on output prevents any possible clipping. - Envelope follower for dynamic control of each effect. - Sequencer for rhythmic control of each effect. - Three special LFO in series to automate morphing. - Hot buttons to change the active effect slot. - Changing a group of parameters at the same time. - Echo module, Sequencer, and Auto morphing synced with the main BPM source. - The effect algorithm and its parameters can be saved as a preset. - Detailed application description and description of algorithms. - Quick info and description of each algorithm used in presets. Classic FX is a universal application for iOS and macOS. It can work on iPhone and iPad as well as Mac / MacBook with M1 chip (and later). Classic FX works on iPhone and iPad standalone, as an Audio Unit or Inter-App Audio module, and supports Audiobus and Ableton Link. On MacOS, Classic FX can works both as a standalone application and as an Audio unit (AUv3) with DAWs and audio unit hosts like Ableton Live, Logic Pro, GarageBand, MainStage, Cockos Reaper, Plogue Bidule, Hosting AU, and other hosts that support AUv3 plugins. All application features are available on iOS and macOS.

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.
