Access Virus TI Snow: MIDI CC, NRPN and OSC map

The Access Virus TI Snow as named OSC addresses — 90 CC, 1 NRPN, 124 SysEx commands — ready to use from Claude (MCP), SuperCollider, Sonic Pi, TouchDesigner or any OSC app via osc-bridge.

Device	Access Virus TI Snow
Vendor	Access
OSC prefix	/virus_ti_snow
Source	🎛️ Derived from an Electra One community preset
Revision	per Electra preset
Upstream	electra-preset
Driver file	devices/access/virus_ti_snow.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/access/virus_ti_snow.json --out-port <N> --in-port <M>

Then send OSC to 127.0.0.1:7777, for example:

osc-bridge osc-send /virus_ti_snow/shape 63

From Claude or any MCP client, the osc-bridge mcp server exposes this driver as virus_ti_snow: ask “what can the Access Virus TI Snow do?” and it reads this map with list_routes. See the MCP guide.
