ramp(f=(a+b)/2)

ramps= a sawtooth at 25 × (a + b) / 2 Hz

A sawtooth LFO at 25 times the average of a and b, in Hz. A positive rate gives a saw rising from −1 to +1, a negative one a falling saw.

Computed in your browser with KINSPIRATION's FUN engine, step by step: this FUN keeps a state, so its output depends on what came before.

WHAT TO KNOW

INPUTS

a and b: two sources sharing the rate.

OUTPUT RANGE

-1..+1, a sawtooth

USE IT FOR

Two controllers that each drive half of the rate.

WATCH OUT

Each input drives half the rate: a 0.2 alone gives 2.5 Hz, a 1 alone 12.5 Hz.

IN THE FACTORY PROGRAMS
