KORG Kingkorg V3 MIDI CC chart, NRPN and OSC map

The KORG Kingkorg V3 MIDI implementation: 11 CC, 96 SysEx commands, each named, for Claude (MCP), SuperCollider or any OSC app.

Device	KORG Kingkorg V3
Vendor	KORG
OSC prefix	/kingkorg_v3
Source	🎛️ Derived from an Electra One community preset
Revision	per Electra preset
Upstream	electra-preset
Driver file	devices/korg/kingkorg_v3.json

Not tested on the device yet

This driver comes from documentation or community data and has not been checked on real hardware. If you own one, a quick test and a pull request promoting it helps everyone — see CONTRIBUTING.

How do you control it?

Find the MIDI ports, then start the bridge with this driver:

osc-bridge detect        # prints the ready-to-run line for what is plugged in
osc-bridge run --device devices/korg/kingkorg_v3.json --out-port <N> --in-port <M>

Then send OSC to 127.0.0.1:7777, for example:

osc-bridge osc-send /kingkorg_v3/eq_high_gain 31

From Claude or any MCP client, the osc-bridge mcp server exposes this driver as kingkorg_v3: ask “what can the KORG Kingkorg V3 do?” and it reads this map with list_routes. See the MCP guide.

Performance MIDI

Notes, pitch bend and any CC are also available: /kingkorg_v3/note/on <note> <velocity>, /kingkorg_v3/cc/<number> <value>, /kingkorg_v3/pitchbend <0-16383>, /kingkorg_v3/program_change <n>.

Limitations

Imported from an Electra One community preset. The mapping reflects the preset author's editorial choices: parameter naming, ranges, and which params are exposed. Untested on hardware in this repo.

Frequently asked questions

Which MIDI CC controls the filter cutoff on the KORG Kingkorg V3?

CC 74 (0–127), named /kingkorg_v3/brightness in SynthHub's map.

How many parameters of the KORG Kingkorg V3 can be controlled over MIDI?

SynthHub's map of the KORG Kingkorg V3 lists 11 MIDI CC parameters, each with its number, range and a readable name; the full chart is on this page.

Can an AI agent like Claude control the KORG Kingkorg V3?

Yes: SynthHub's hosted MCP server knows the KORG Kingkorg V3's MIDI map, and its browser relay lets the agent send it parameter changes or load a sound, each sound change confirmed by you.
