Start with fire

Every preset in FLEX is mix-ready and built to slot straight into your track. Whether you’re going for cinematic strings or club-ready bass, you’ll find sounds that land hard—no heavy tweaking required.

Sound design, simplified

No synth degree required — FLEX gives you just the controls you need, and none you don’t. Each preset includes custom macros to shape your sound fast, plus filters, envelopes, and effects when you want to go deeper.

Fresh sounds, always

New FLEX Packs drop all the time, with sounds built for drill, trap, EDM, lo-fi, and more. Whether you’re stacking free kits or grabbing premium packs, there’s always something new to play with.

Pick your vibe. There’s a pack for that.

Each FLEX Pack nails a different genre, so it’s easy to lock in the mood you want. Punchy drums, spaced-out pads, bold leads — whatever you’re feeling, there’s something in the store to get it moving. Some are free, some are paid, but all hit hard.
