Blue Cat's Crafters Pack is the ultimate audio toolkit to design your own custom toolbox:
Write your own effects or virtual instruments with Blue Cat's Plug'n Script, create custom MIDI controllers with Blue Cat's Remote Control, and connect everything together with Blue Cat's PatchWork, as a plug-in or standalone application.
With Blue Cat's MB-7 Mixer, create your own multiband processors by applying plug-ins of your choice (including your own!) to distinct frequency bands.
The "Multi" analysis plug-ins series are also included, to help you during the creation process: analyze and match existing gear, or check how your processing chains are impacting the signal.
If you really care about having tools that adapt to your own workflow, or if you are a programmer and want to speed up your development process, check it out: Blue Cat's Crafters Pack will unleash your creativity.
