- FX — Edit parameters for all 5 FX slots. Each slot remembers its algorithm independently.
- LFO / EG / EF — Full parameter control for all modulation units.
- Mixer — Level and routing parameters for all 5 FX slots.
- VP (Virtual Patch) — 32-patch modulation routing with source, destination, intensity, and polarity.
- VP Curve (Mapper) — Graphical editor for the VP Mapper curve. Click to add points, drag to move, right-click to delete.
- Librarian — Import
.presetfiles, browse loaded presets, and send them to the device. - DSP Usage meter — Real-time DSP load bar in the header. Algorithms that would exceed 101% are dimmed and disabled.
- Send All / Send 1 Tab — Send all edited parameters at once, or only the current tab.
- Chrome (or any Chromium-based browser) with Web MIDI API enabled
- KORG KAOSS PAD V connected via USB MIDI
- Connect your KAOSS PAD V via USB.

3g= Global Channel byte (g = 0-based channel number)- Float encoding: IEEE 754 big-endian split into 7-bit × 5 bytes
- Mapper modes:
00=Remove,01=Move,02=RemoveAll,03=Init,7F=Add
- Removed Google Analytics to improve privacy and eliminate third-party data collection
- Fixed: DSP usage limit check now correctly blocks combinations at exactly 101% (was allowing 101%)
- Initial public release
- Full parameter editing for FX / LFO / EG / EF / Mixer / Virtual Patch
- Virtual Patch Curve (Mapper) GUI
.presetfile import and send (Librarian)- DSP Usage display and algorithm selection restriction
