Everything you need, without digging through confusing menus.

Shape your music

Adjust music EQ and tonal balance with a clear response graph so you can see what you are changing.

M

Polish your vocals

Tune microphone tone, dynamics, reverb, and echo from dedicated screens instead of one crowded panel.

Control every output

Fine-tune Main, Center, Surround, and Subwoofer paths for a more balanced karaoke system.

P

Manage presets safely

Keep SonKuPik official presets and your own local presets together, then preview or upload deliberately.

GET STARTED

From download to tuning in three steps.

1

Install

Download the Windows Setup package and install SonKuPik K500.

2

Connect the K500 by USB. The app reads the processor state before enabling live editing.

3

BUILT CAREFULLY UNDER THE HOOD

Simple for users. Strict with the hardware.

The friendly interface sits on top of a conservative device model: hardware readback is authoritative, preset files are validated, unknown commands stay read-only, and permanent writes use verified transactions.
