Frames by Mutable Instruments

But what makes Frames truly unique is the way in which channel/CV levels can be controlled, using a technique inspired by computer animation. Frames allows up to 64 configurations of the 4 level knobs to be stored and recalled throughout the course of its big Frame knob.

By rotating the knob (or sending a CV to the Frame modulation input and adjusting its amount with the attenuverter), the configurations are morphed into one another.
