Peter Dines has released Fixed Filter Bank, a free ensemble for Native Instruments Reaktor.
My version adds one refinement – you can sweep the overall range of the filter up and down to better match your source material and project. Taking a look inside, you can see that there are only two filter modules, but they’re polyphonic, with each voice accounting for one filter band. This makes a neater structure, and one that’s easier to modify.
Front panel controls are tool-tipped and should be self explanatory.
Fixed Filter Bank is a free download at Reaktor Tips.
