Blue Cat Audio Releases PatchWork 1.5 and MB-7 Mixer 2.4

Blue Cat Audio have updated both PatchWork and MB-7, introducing new features such as VST relocation, Logic X MIDI FX compatibility in PatchWork, as well as fixes and improvements.  

Paris, France, 2014/10/20: Blue Cat Audio ( ) have released an update for Blue Cat's PatchWork and MB-7 Mixer plug-ins, improving compatibility with third party plug-ins and adding new interoperability features.

Both plug-ins can now load more VST and Audio Unit plug-ins (fixing compatibility issues with several plug-ins manufacturers). For improved interoperability between systems, plug-ins' state are now retained even if the plug-ins are missing, and VST plug-ins can be relocated if moved. The new PatchWork 1.5 plug-in also supports MIDI FX Audio Units and can be loaded as a MIDI FX in Logic Pro X to quickly build complex MIDI effects chains (full change list below).
