With Kilohears Toolbox 2 the biggest RE bundle got even bigger. The versatile collection is now expanded with kHs Transient Shaper, adding direct control over the character of both the attack and sustaining sections of the sound in a way that’s simple to understand and tweak

The kHs Toolbox gives you access to 25 super efficient Rack Extensions that will change the way you think about sound design in Reason. These plugins where designed to do away with as much complexity and frustration as possible, making your workflow so much faster and more fun. By saving your valuable time with straight-forward interfaces and easy-to-understand labels you can focus on creativity.

On top of that the kHs Toolbox plugins use the smallest possible rack sizes so you can fit many effects on a smaller screen space.
