Choreographs Slate and Ash is a highly creative sound design tool built to capture the essence of motion and pattern. With over 150 modulatable controls, this instrument allows you to manipulate sound with unprecedented flexibility. By connecting sample-based oscillators with a sophisticated architecture of musical devices, Choreographs offers an expansive range of sonic possibilities—from polyphonic synthesizer to drum machine, sampler, and granular processor.
The instrument’s core concept is the exploration of movement and the interaction between composition and performance. Like a choreographed dance, each sound emerges from a collection of waves, signals, and pulses as you shape it in real-time. The powerful sequencers, LFOs, and random modulators give you the ability to craft sounds that are both spontaneous and designed, forming a dynamic bridge between performance and composition.
Key Features:
Modular Sound Design:
Over 150 modulatable controls allow for complex sound manipulation, starting from polyphonic synthesis and evolving into drum machines, samplers, and granular processors. Use LFOs, MIDI CCs, random signals, and step-modulators to inject movement and life into your sounds.Vast Sample Library:
With over 400 sample sources, Choreographs Slate and Ash covers a broad range of tones—from analog synths and modular oscillators to acoustic instruments and noise layers. This expansive library offers rich textures and a wide variety of timbres.Harmonic Sequencing:
Pitch modulation is a central feature, detaching pitch from envelope triggering. This allows for intricate sequences, LFO-driven melodies, and fragmented polyrhythms. The scale quantizer intelligently organizes chaotic pitches into harmonious sequences.Euclidean Sequencer:
The unique Euclidean sequencer generates abstract sequences and evolving polyrhythms based on mathematical symmetry. It produces counterpoints, harmonic progressions, and angular rhythms that offer a fresh perspective on traditional sequencer patterns.
Sample-Based Synthesis and Sampling:
Easily load samples into the engine by dragging them into the three voice slots. Then shape and manipulate them with a vast range of parameters. You can even drop your samples into existing patches to instantly transform them, giving you a quick route to new, unique sounds.Curated Engine States:
The engine features 122 curated states that offer complex, evolving sounds. These states provide everything from reverberating drones to sharp percussion and polyrhythmic textures that push the boundaries of conventional synthesis.
Technical Details:
- Size: 22GB download
- Samples: 8,387 samples
- Presets: 661 engine preset patches
