Maker: Sequential
Version: per Electra preset
Source: Electra One preset
OSC prefix: /prophet_600

Use 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/sequential/prophet_600.electra-community.fw-gligli.json --out-port <N> --in-port <M>

Then send OSC to 127.0.0.1:7777, for example:

osc-bridge osc-send /prophet_600/oscillators/osc_a_freq 63

From Claude or any MCP client, the osc-bridge mcp server exposes this driver as prophet_600: ask “what can the Sequential Prophet 600 do?” and it reads this map with list_routes. See the MCP guide.

Frequently asked questions

Which MIDI CC controls the filter cutoff on the Sequential Prophet 600?

CC 23 (0–127), named /prophet_600/cutoff in SynthHub's map.

How many parameters of the Sequential Prophet 600 can be controlled over MIDI?

SynthHub's map of the Sequential Prophet 600 lists 47 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 Sequential Prophet 600?

Yes: SynthHub's hosted MCP server knows the Sequential Prophet 600's MIDI map, and its browser relay lets the agent send it parameter changes or load a sound, each sound change confirmed by you.
