## What is KG?

[From '80s Legend to Modern Era: Put the Feel of Authentic Hardware in Your Hands]

"KG-SQUARE" is an analog modeling synthesizer app that packs the aesthetics and intuitive operation of professional hardware into an iPhone-sized format.

While inheriting the simplicity of its predecessor, "FX-SQUARE," this version delivers a massive upgrade to both its sound engine and UI. From thick, punchy synth basses to dreamlike, immersive pads, it features a wide range of high-quality tones ready to elevate modern music production.

◆ Key Features

Highly Immersive Hardware-Style UI: Designed with lifelike 3D knobs and LED indicators, giving you the professional feel and excitement of tweaking real gear.

KAOSS PHYSICS (XY Pad): Simply glide your finger across the right-side pad to dynamically control Cutoff, Resonance, and effects. Create sweeping, space-like tonal shifts in real time as you play.

Two Powerful Effects: Equipped with "REVERB" for deep spatial warmth and "DELAY" to add movement to your echoes. Seamlessly blend them using dedicated knobs.

Polished Sound Presets: Carefully selected, massive sounds unique to analog modeling, including MP Bass, MP Lead, MP PolySynth, and more.

Smooth Playability: Features responsive mini-keys along with screen-edge protection to prevent accidental touches, keeping you focused entirely on your performance.

Perfect as a companion synth for music production, on-the-go sound design, or intuitive finger-play performances. Experience the ultimate analog modeling sound today!
