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.
