Each month, SynthCtrl releases an exclusive Monthly Mystery Box, available only to 100 worldwide. Every box includes more than $100 worth of Serum Packs for just $14.90 that is an 85% discount, which is HUGE!!, featuring a curated selection of packs and presets to keep your creativity flowing all month long.

What's included?

• 4 Full Serum Packs from our already big collection with more than 500 presets ready to inspire new tracks.

The box focuses on a different genre every month, from Synthwave and Disco to Neo Soul and Future Bass, delivering a new wave of inspiration with every release. Once the 100 boxes are gone, they won’t return until next year when the 12-month cycle begins again in January. Unlock creativity, surprise, and something truly rare, all in one box.

SEPTEMBER HINT

Think hazy guitars, dreamy synths, bedroom recordings, and melodies that feel like they were made at 2AM. Add warm, imperfect textures, catchy guitar riffs, nostalgic chords, lo-fi production, and those little imperfections that somehow make everything feel more human. 

This month’s sounds are all about late-night creativity, intimate productions, and turning simple ideas into something unforgettable.

Can you guess what’s waiting inside the September Mystery Box?
