"QuantiChord" is a MIDI effect that generates chords from incoming notes and quantizes the results to a pre-defined scale. It can be used as a standalone application or as an AUv3 MIDI effect plug-in. The chord is generated by adding up to 8 transposed notes to the original note played. Once the chord is generated, it is quantized to limit it to the selected output scale. The application supports full internal and external MIDI connections for input and output. An internal sound bank is included. The AUv3 MIDI effect plug-in supports multiple instances. A compatible host is required to run the plug-in. The host must support the Audio Unit v3 (AUv3) MIDI effect format. Hosts supporting AUv3 MIDI effect on iOS: Logic Pro, Cubasis, Beatmaker, AUM, Audiobus, NanoStudio, Auria Pro, apeMatrix. Hosts supporting AUv3 MIDI effect on macOS: Logic Pro 10.7 or later. Features: • Standalone application and AUv3 MIDI effect plug-in • 8 transposing sliders from -24 to +24 semi-tones (+/- 2 octaves) • 1 global transposer slider • Scale quantizer • Lockable parameter protection when switching presets • Resizable keyboard • Multitasking support • Stop "Audio Background" automatically after inactivity (15 min, 30 min, 1 h, 2 h, or never) • Sample-accurate timing • Internal sound bank • Receiving MIDI from external MIDI sources • Internal routing of inputs, outputs • Send MIDI to a virtual port usable as MIDI input by other "Core MIDI" compatible apps • Random creation of presets • Presets browser • "Program Change" support • Preset sharing support by "AirDrop", "Mail", "Messages", and other supported services • Native iCloud support • "iCloud Drive" support in the "Files" app on iOS and "Finder" on macOS • Full support of "Windowed Apps" mode on iPad • Undo/Redo Supported MIDI connections: • Virtual "Core MIDI" connections between applications • Any compatible MIDI interface • MIDI over Wi-Fi • MIDI over Bluetooth

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.
