diode(a−b−.5)

diodes= a - b - 0.5, or 0 where that is negative

diode(a-b) shifted down by 0.5: a passes only when it exceeds b by more than 0.5. Only positive results matter: a negative result becomes 0, which limits a bipolar signal to unipolar values.

WHAT TO KNOW

INPUTS

a: the signal; b: the threshold.

OUTPUT RANGE

0..+0.5 for a unipolar a

USE IT FOR

A high threshold: only the top half of a unipolar source (b OFF: from 0.5 up), a wide dead zone.

WATCH OUT

A unipolar a gives at most 0.5, so the destination needs a large depth.

HOW TO ON YOUR K2700 · 2046 Editor Template

The factory does not route diode(a-b-.5) to a sound on its own: set one up on 2046 Editor Template and hear it on the pitch.

  1. In Program mode choose 2046 Editor Template, a plain one-layer program to build on (KEYPAD, 2046, ENTER).

    Program mode with 2046 Editor Template

  2. Press EDIT, then MORE and DSP MOD. On the Pitch row set Source 1 to FUN2 and its Depth to 1200 ct: FUN2's result, −1 to +1, now bends the pitch up to an octave either way.

    The DSP MOD page of 2046 Editor Template, layer 1, the cursor on Depth (1200 ct)

  3. MORE, then LFO+. On the FUN2 row set Input a to MWheel and Input b to OFF.

    The LFO+ page of 2046 Editor Template, layer 1, the cursor on Input b (OFF)

  4. Move to Function and turn the Alpha Wheel to diode(a-b-.5).

    The LFO+ page of 2046 Editor Template, layer 1, the cursor on Function (diode(a-b-.5))

  5. Move the mod wheel: nothing happens in its lower half; from halfway up the pitch rises, to 600 ct at the top, wheel − 0.5.

  6. Press EXIT and answer NO to leave the factory program as it was, or SAVE to keep your version on a USER ID.
