SSL's V4.3 update maps System T's controls to any OSC-compliant device, and brings SolidPitch vocal processing and bigger bussing across from its Live consoles.
Solid State Logic is opening up its System T broadcast platform to outside control at IBC 2026, with a V4.3 update built around Open Sound Control. The addition lets third-party mixers and controllers operate System T’s console parameters over standard IP, so an OSC-compliant device can drive the desk without any dedicated SSL hardware in the room.

System T V4.3 features at a glance
- OSC control of System T from any OSC-compliant mixer or controller over standard IP, no dedicated SSL hardware needed
- Mappable parameters including faders, mutes, PFL, AFL and path labels, expandable via Event Manager
- OSC as an input and output in Event Manager, working alongside GPIO, Ember+ and MIDI
- Scene automation fired directly by number for snapshot-style recall
- External mic preamp control across the Net I/O range from the Tempest Control App
- Meter bridge updates: follow active fader bank metering on the S500/S500m, plus the Bus Compressor Effect Meter on the bridge
- Track buses gain per-channel send flexibility, matching stem and aux buses
- Permanent Path Linking with up to 48 permanent link groups
- SolidPitch vocal processing (tuner, doubler and harmoniser) across System T, including the Virtual Tempest Engine
- Showfile capacity up to 500 scenes
- Remote power-off for safe scheduled shutdown
It’s built for ad hoc and distributed setups, where a remote operator often needs only a slice of control. “A remote operator at a venue might just need console monitor functionality or access to select local faders – all that can be controlled via a compact hardware controller for smaller setups,” says SSL Product Manager Berny Carpenter. Faders, mutes, PFL, AFL and path labels are all mappable, and the list can be extended to anything exposed through System T’s Event Manager.
OSC now works as both an input and output in Event Manager, so it can trigger and respond to events alongside GPIO, Ember+ and MIDI, and scenes can be fired directly by number for snapshot-style recall. The update also adds external mic preamp control, letting operators set the gain of any SSL preamp across the Net I/O range from the Tempest Control App over OSC.
V4.3 brings changes beyond the control side, too. The meter bridge gains a follow active fader bank option on the S500 and S500m for metering that tracks whatever’s on the surface, and the Bus Compressor Effect Meter can now go on the meter bridge itself. Track buses pick up the same per-channel send flexibility as stem and aux buses, raising the number of independent sends for larger shows.
Two features carried over from SSL’s Live consoles round it out: Permanent Path Linking, which holds up to 48 permanent link groups between paths, and SolidPitch, an onboard vocal effect covering everything from gentle tuning to a doubler and harmoniser, available right across System T including the Virtual Tempest Engine. Showfile capacity also rises to 500 scenes, and a new remote power-off lets a console shut down safely at the end of a broadcast.
