Astra is a powerful polysynth offering a wide array of oscillator sources including FM, wavetable, granular, analog, and sampler options. Its design supports extensive sound customization, enabling musicians to craft everything from sharp rave stabs to lush, evolving strings. Users can integrate their own samples to create truly unique soundscapes, making Astra suitable for deep sound design and genre-spanning musical exploration.

The synth provides intuitive control over sound shaping through its drag-and-drop macro system, allowing multiple parameters to be adjusted simultaneously for dynamic performance tweaks. The Macro Sequencer introduces rhythmic patterns to these controls, perfect for trance-like motifs or hypnotic effects. Additionally, Astra’s Note Sequencer offers precise programming of pitch, velocity, and gate, empowering creators to build intricate arpeggios, acid lines, or sample-based percussion loops that sync tightly with their compositions.

With a 10-slot Modulation Matrix, Astra enables complex modulation routing to bring sounds to life with sweeping morphs and transformations reminiscent of classic hardware synths. The instrument comes packed with 225 presets to spark creativity, alongside access to thousands more via Splice Sounds, all auditionable directly within the DAW. Included free with Splice Creator Plans and available as a trial, Astra combines depth and ease for musicians seeking expansive sonic possibilities without distraction.
