The 256e CV processor applies piecewise-linear transformations to control voltages using a configurable breakpoint, enabling non-linear CV shaping

Each of the four identical sections of the 256e takes two CV inputs, selects between them (or blends them), and applies a transformation. Without a breakpoint, the function is a linear remap between the 0V and 10V endpoints. With a breakpoint added, the function becomes two-segment piecewise linear, with the breakpoint’s input voltage and output voltage set by dedicated knobs. This allows operations like inversion, multiplication of two CVs, clipping at a threshold, and amplitude-following. Input selection can itself be voltage-controlled, crossfading between two sources.

Examples

Use the 256e to create an exponential-like velocity response: set breakpoint near the high end so soft MIDI velocities produce little CV change while hard velocities compress into a narrow output range.

Assessment

Describe the 256e’s output when both endpoints (0V and 10V) and the breakpoint are used to create a knee at 3V input / 8V output. Draw the transfer curve.
