BLEASS Sidekick is a combination of a kick drum synth, a step sequencer, and a ducker (aka a sidechain compressor). The result is a plugin that provides a unique way to create exciting rhythmic dynamics within your music. The kick drum synth uses an analogue-style engine inspired by vintage beatboxes, which allows it to create a wide range of classic analogue kick drum tones with ease. This synth can be triggered by the built-in 16-step sequencer or by an external MIDI input; its sound can be mixed with the audio passing through the plugin, be used to trigger the plugin’s ducker stage, or both. Used without the ducker, BLEASS Sidechain makes it easy to add your own kick parts to loops and other percussive parts. Bringing in the ducker causes the input signal to reduce in volume whenever the kick synth is triggered. When used on a drum loop this lets you impose your own creativity on the underlying feel and beat of the loop, ducking-out the loop’s kick sound and pattern so that you can replace them with a sound and pattern that you have crafted. Perhaps BLEASS Sidekick’s best trick, though, is to use the kick synth and sequencer purely as a trigger for the ducker. This lets you create fascinating and detailed dynamic rhythms within any part or track, whether individual instrument or an entire mix. This plugin is AUv3 compatible and offers Multi-Bus output (within AUM) as well as Midi Input. More information and tutorials available on https://www.bleass.com/sidekick

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.
