ScaleMatrix is a player Rack Extension where you can define and easily recall up to seven separate scale and chord configurations with timing and velocity options for creative composing or as a very useful performance tool. This devices interface encourages user created scales for very quick creative flow, but also comes with an extended version of the TonicMint scale library and plenty of patches, some simple, some advanced so we think the ScaleMatrix is a helpful addition to the Reason Rack whether you need to get ideas out fast or want to take a thoughtful slow road.

Product details
