Blue Cat's PatchWork is a universal plug-ins patchbay that can host up to 64 VST or AU plug-ins into any Digital Audio Workstation (DAW) in one instance.

It is possible to chain effects in series or create up to 8 parallel chains that can be activated independently. This lets you create your favorite effects or instruments configurations within the plug-in, without the need for multiple busses. These configurations can be saved as presets and recalled instantly, or shared with multiple DAWs, using any plug-in format (full list below).

Despite the name, you can forget about wires or cables: configuring plug-ins routing is as simple as adding or removing a row or a column in the rack's matrix.

For each plug-in slot, latency compensation, presets management, undo/redo integration, and individual plug-in bypass are included for optimal operation. The plug-in also stores the position of the window for each plug-in so that the layout is restored with your session or saved with presets.

Also, sub plug-ins can be automated or controlled with external control surfaces using Blue Cat's PatchWork parameters mapping capabilities.

This product is available as an audio plug-in (effect or a virtual instrument) and standalone application, so that it can used alone or inserted on any type of track in your favorite DAW, with up to 8 audio channels.

Input and output level meters are also included to monitor the signal that is dispatched to inserted plug-ins.

Main Features:

  • Configurable VST or Audio Unit plug-ins rack: host up to 64 third party plug-ins or instruments in series or parallel.

  • Available as an effect, virtual instrument or standalone application.

  • Build your own effects chains: up to 8 "pre" and "post" plug-ins slots to chain plug-ins in series.

  • Parallel processing made easy: up to 8 parallel plug-ins chains, with phase flip, solo and gain controls.

  • Host up to 8 virtual instruments in parallel and mix them within the plug-in.
    Global Dry/Wet control ("Mix").

  • Parameters Mapping: map sub plug-ins parameters to automate them or use a control surface.

  • Flexible MIDI routing: connect sub plug-ins together or with the host application.

  • External side chain and multiple outputs support.

This could be a big answer for those who switch between multiple DAWs for clients but want access to complex programming of instruments and effects easily. I use Logic X, Cubase 7.5, Live 9 (all Mac) and Samplitude/Sequoia (PC). I'll get back once I can play with it in my various rigs and see if presets can work well, especially on different OSes.

No vst3 support= massive fail for me. DDMF Metaplugin DOES offer vst3 support. I bought this software (Blue Cat Patchwork) & I feel ripped off as there was no mention anywhere of vst3 support being excluded. Blue Cat's support team haven't offered a solution pointing me towards the vendor I purchased from to get a refund (who will prob blame Blue Cat). It is an absolute short-fall in the program & omitting one of the most popular plug-in formats makes it virtually unusable for me.

Nameless Blue Cat support, "resources are limited", "you should've used demo", "contact vendor for refund".

We are sorry that you feel ripped off. I you had purchased the plug-in from us we could have issued a refund, but we do not have control over the other resellers you may purchase the software from.

Sorry for a nuubi question but I'm a bit confused. I recently saw a post in Pro Tools Expert that claimed the Empirical Labs Dstressor plug-in (RTAS 32) would run in PT 11 inside Patchwork. If that runs, will Auto-Tune_Evo_RTAS also run inside patchwork in PT 11? Thanks! Bill.

26 July 2014 at 6:44pmsyndicat

Yes, it seems you are a bit confused: Blue Cat's patchwork adaptor allows running VST and AU plugin types "as" AAX/AAX64 (PT 10/11) and in other types of hosts / DAWs. It is not a RTAS -> AAX64 adaptor. Means; sou are able to run the VST and/or AU version of Antares AutoTune in Pro Tools 11, but not the RTAS version.

but: The current AutoTune is available as AAX64 too - needs no adaptor to run it in PT 10 and 11 and if you have a AutoTune license afaik you are allowed to download and run each of the plugin variants. If you have an older license you may choose the VST or AU version of your AutoTune version to use it within Patchwork. So it is not clear what's your real problem here ß)

Thanks for replying.

Sorry for an ignorant question but i wonder whether Patchwork can input audio independent of the host DAW? I'd like to use it as a VST in Synfire, a strange program that has no audio input routing. Many thanks...B.

Blue Cat's PatchWork does not have external MIDI or Audio inputs. It is designed to only get the audio and MIDI data from the host application.

ok thanks for the quick reply! B.
