Essential Information About Blue Cat Connector Software
- Real-time audio and MIDI routing between plug-ins, applications, and even multiple computers, just like with real cables in a studio.
- Minimal latency with precise buffering control, down to 0 samples within the same host.
- Reliable connections even between unsynchronized systems thanks to built-in resampling and drift compensation.
- Professional workflow: transport synchronization, surround and Ambisonics support, MIDI automation, preset management, and resizable interface.
What Blue Cat Connector Is For
Blue Cat Connector is an audio and MIDI streaming plug-in designed to extend your studio beyond the usual limits of a DAW. It allows you to instantly connect tracks, buses, virtual instruments, or effects between different plug-in instances, whether within a single session (advanced internal routing) or between multiple applications on the same machine, or even across multiple networked computers.
It is the ideal tool to build a hybrid studio: use a second computer as an instrument rack, link an audio editor with a DAW, integrate a broadcast engine, or create creative setups that are difficult to achieve otherwise, such as controlled feedback loops with plug-ins.
Main Features
Universal audio and MIDI routing, without constraints
Connector acts like a true virtual patch bay. It can send and receive audio and MIDI, and even handle scenarios where a single instance both sends and receives streams to simplify configurations. It works in most modern production environments thanks to its availability in common plug-in formats on Mac and Windows.
Latency and stability under control
The plug-in offers fine buffering adjustment to optimize the balance between smoothness and latency depending on your use (monitoring, re-recording, software reamping, etc.). Starting with version 1.4, Connector can estimate, compensate, and report connection latency to maintain consistent timing in demanding projects.
Stability has also been improved, especially when the sender is under heavy CPU load, with more precise status reporting on the receiver side.
Sample rate and clock compatibility: "it just works"
For multi-application and multi-machine studios, differences in sample rates and unsynchronized clocks are often a hurdle. Connector includes resampling and drift compensation that enable seamless connections between heterogeneous environments without having to lock everything to the same configuration.
Advanced synchronization and MIDI (version 1.4)
Connector can now transmit signals compatible with MIDI Timecode (MTC) and MIDI Clock to synchronize applications with each other. Clock anticipation management even allows compensation of connection latency for more natural synchronization. MIDI support is extended with SysEx handling, a MIDI Thru option to merge incoming and received events, and sending Bank Select and Program Change messages when changes are made in the interface, useful for keeping an external controller in sync.
Multichannel production: surround and Ambisonics
For immersive projects, Connector can carry up to 32 audio channels, making it suitable for surround and Ambisonics routing, multichannel stems, or bridges between specialized tools.
"Studio" ergonomics by Blue Cat Audio
Designed for daily use, Connector includes a customizable interface (zoom and transparency), a Smooth Bypass for noise-free activation/deactivation, as well as Undo/Redo, a full-featured preset manager, and the ability to copy/paste the plug-in state between instances. CPU optimization is carefully handled: in the absence of signal, processing can automatically stop to save resources.
