Filter Blender puts three of twelve analog-style filter models on a triangle and mixes them by distance. A parked corner is a single filter. A moving dot is a parallel blend, and a drawn path can lock to tempo. The launch price is $39 until 15 November 2026, then $68, sold direct from UB DSP. See the Filter Blender first look for the model list and the comparison with Volcano 3 and FilterShaper 3.
