From rave stabs to radiant strings
Astra’s collection of oscillator sources range from glassy FM and granular glitchiness to classic analog warmth. It crushes lead sounds and sub-shaking basses, and definitely holds its own with evolving arps and transformational FX. You can even use your own samples—for sound design that’s totally yours. Take your tracks to new sonic territory with Astra.
Total control
Personalize any existing Astra preset, or design sounds from scratch. Just drag and drop parameters to the four macros, name them what you want, and adjust multiple parameters in one motion. The Macro Sequencer lets you dial up the vibe, by assigning a step sequence to the macros—for trance-like patterns and hypnotic rhythms.
“Astra’s versatility is so dynamic—with one knob I can transform something from a kick to a synth.”
Make your music move
Astra’s Note Sequencer lets you program rhythmic, in-sync synth sounds that add mind-opening movement to your music. With customizable sequencer lanes for pitch, velocity and gate, you can create squelching acid lines from scratch, turn your samples into percussion loops, or create and recall rich arpeggios locked to the scale of your choice. Your wild polyphonic dreams are Astra’s one assignment.
Creativity not complexity
Astra’s 10-slot Modulation Matrix lets you assign intricate interactions between its different modules—just drag-and-drop parameters to Mod slots. Like a hardware synth, Astra can sweep, morph and transform, to add layers of creativity to your musical creations. Etch your mark on the music you make.
