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. Please Note: Not all features are currently compatible with Auria.

PolyBud is a multitrack polyrhythmic AUv3 MIDI sequencer. You can add multiple note or MIDI CC tracks to the each pattern. The note tracks has the note, velocity, gate, ratchet, probability and randomisation modes. You can set different step lengths to the each mode which would introduce polyrhythmic variations immediately. Another great feature is the each track can run in a different rate which is great for creating unique polyrhythmic sequences. Also, you can assign different MIDI channels to the each track so that you can control multiple synths within a single PolyBud pattern. The MIDI CC tracks is great for modulating the synth parameters. You can introduce polyrhythmic modulations by setting the different step lengths and different rates to your MIDI CC tracks. Also, you can set a ramp value for smoothing up the CC value changes per step. If you set the ramp value to 0% then you can have the classic sample and hold modulation. PolyBud is a MIDI app and it don't produce any sound of its own. You need to route PolyBud's MIDI out to your audio apps in order to run PolyBud. For the AUv3 plugin, you need an AUv3 host app such as AUM, Cubase, NanoStudio, ZenBeats, BeatMaker, apeMatrix etc.
