Blue Cat Audio releases Network Audio Protocol V2 Free Update

Blue Cat Audio has announced a major update of their network audio/MIDI communication protocol, with the release of Blue Cat's Connector 1.4, Freeceiver 1.2 and PatchWork 2.72.

This free update allows the plug-ins and applications to carry up to 32 audio channels for surround and ambisonics streaming, and now supports System Exclusive MIDI data. It also adds network latency compensation and transport/clock synchronization capabilities to synchronize applications and audio streams together, regardless of the network latency and many other improvements and fixes (full list below).

Connector, the virtual cable plug-in that lets you connect applications together locally or thru the Internet, provides the core features of this new protocol. Freeceiver is a free implementation that can receive audio and MIDI signals sent by Connector anywhere. PatchWork, the virtual patchbay for plug-ins, provides network processing capabilities using this network protocol.

New In Connector 1.4/Freeceiver 1.2

Connector Protocol V2:

• Latency compensation: Connector can now evaluate, compensate and report the latency of the connection.
• Transport synchronization: Connector can now send MIDI Timecode (MTC) and MIDI Clock compatible signals to synchronize applications together.
• Manage synchronization with clock anticipation: the clock signal can compensate the connection latency to synchronize apps with no delay.
• Carry up to 32 audio channels for surround and Ambisonics support.
• MIDI System Exclusive (SysEx) support.
• Plug-in/app Features:
• The plug-in can now receive and transmit SysEx MIDI events.
• MIDI Thru option to merge incoming MIDI events with received events.
• Improved connection stability when sender under high CPU load.
• Improved connection status reporting in receiver.
• Find currently selected preset easily in the menu (folders containing the preset now display a check mark).
• New option to cycle next/previous preset in current bank.
• The plug-in can now send Bank Select and Program Change messages upon changes in the user interface to keep in sync with an external controller.
• Fixed memory leak in receiver when using resampling.
• Mac: Fixed location of text edit boxes changing when closing and re-opening the plug-in GUI in previous release.
• ASIO Driver:
• ASIO Positioning Protocol (A.P.P.) support: the ASIO driver can now control the transport of applications supporting the A.P.P. protocol (Cubase, Nuendo...) when being sent a clock signal.
• ASIO buffer size can now be set from the driver settings window.
• Audio compression and UPnP options can now be set from the driver settings window.

New in Patchwork 2.72:

Network Audio:

• Connector Protocol V2 support for network audio device.
• Application now reports plug-ins latency to the network client when running in network mode.
• Network audio device can now manage up to 32 audio channels.
• Adjust compression settings and activate UpnP for the Connector slave network audio device.
• Fixed application sometimes dropping local MIDI events when using the network audio device.
• New Features:
• Reported latency is now displayed in the status bar (bottom right).
• Route MIDI events from hosted plug-ins back to PatchWork's input with the new MIDI Loopback port.
• New "learn once" mode for MIDI and macro controls.
• Fixes:
• Fixed issue with some older VST2 instrument plug-ins not receiving MIDI events (such NI Kontakt 6) in previous release.
• Fixed VST3 plug-ins sometimes not updating meters when loaded in PatchWork.
• Fixed AAX effect plug-in not loading anymore in Pro Tools 11 and earlier.
• Improved WASAPI driver support for some audio devices in the Windows application.
• Fixed Arturia VST3 plug-ins editor not re-opening properly when closed with the plug-in slot button.
• Fixed Audio Player crashes when using file with less channels than the plug-in.
• Fixed Audio Player not properly syncing its playback position when resampling.
• Fixed generated MIDI clock sync issues when already slaved to another MIDI clock.
• Fixed occasional performance issue when controlling PatchWork parameters via MIDI in the VST/VST3 plug-in.
• Fixed CPU meter display sometimes off by one pixel.
