Mutable Instruments Frames Mixer/Keyframer (18HP)

Full Description

20 Configurations

The Frames Mixer/Keyframer allows up to 20 configurations of the 4 gain knobs to be stored and recalled throughout the course of its big Frame knob. By rotating this knob (or sending a CV to the Frame modulation input and adjusting its amount with the attenuverter), the configurations are morphed into one another.

With a bit of patching and imagination, Frames can also be repurposed as a 4-channel sequencer, a multi-stage envelope generator or a trajectory generator for quadraphonic panning.

Features

An analog mixer…

4-channel voltage-controlled mixer based on the V2164 IC

• 4 DC-coupled signal inputs
• 1 global input, sent to all unconnected inputs, and normalized to a precision voltage reference (+5V or +10V)
• 4 DC-coupled channel outputs
• 1 global mix output, collecting signals from all unpatched outputs, with a -6dB gain

… under digital control

• 12-bit digital control of the gains for the 4 VCAs
• Up to 20 keyframes, each keyframe storing VCA CVs for each channel
• Per-channel easing curve selection: stepped (no interpolation), linear, accelerating, decelerating, sine, bouncy
• Per-channel CV/VCA response selection, from linear to logarithmic

Specifications

• CV input impedance: 100k
• Audio input impedance: 100k (25k for the global input in some configurations due to normalling)
• Fastest modulation rate: 15kHz
