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.

ChordBud 2 is a MIDI chord sequencer for building unique chord progressions in minutes. Under the hood is a powerful music theory engine with over 40 scales. Select the scales to work with and see them laid out top to bottom on one screen, with the chords inside each scale running left to right, compare scales side by side, or borrow chords from one another through modal interchange. By default, every chord inside the current scale and key is presented at once, and the key can be changed anytime. The settings menu also offers chord progressions to work within, showing only the chords that belong to the selected progression. Build as many patterns as needed, each with its own key, scale, and chord progression. Long-press a pattern to copy, paste, or delete it, with full undo/redo backing every edit so experimentation stays risk-free. Patterns can be triggered via MIDI CC messages, enabling automation or a full song mode. Triads are just the starting point — chords can be extended with add/sus/6/7/9/11/13 and more modifiers. Tap any chord on the timeline to open the chord editor and adjust its mode, velocity, octave, inversion, key, or division. Edits apply live while the sequencer plays, so changes are audible immediately. On the timeline, chords can be repositioned by dragging, or resized by dragging their right edge. Pinch to zoom in or out, or zoom in further to work precisely within subdivisions. Standalone, ChordBud 2 includes a built-in piano sampler for instant playback with zero setup, alongside MIDI, virtual MIDI, and Bluetooth MIDI connectivity for hardware and software instruments. An AUv3 plugin version is also available, dropping straight into any DAW to drive instrument tracks from inside a session. Note: ChordBud 2 AUv3 plugin is a MIDI sequencer app. It does not produce sound itself. You need an audio app in order to get sound. Just route ChordBud 2's MIDI Out to your audio app's MIDI in and arm the sequencer.
