H949 Harmonizer: Pitch Shifter and Time-Reverse Effects Plugin by Eventide Free Download

The MicroPitch mode is built for small pitch changes rather than full harmony intervals. Eventide notes that the hardware used it for double-tracking emulation, and the display's 0.1% pitch resolution makes fine tuning practical.

The Random control adds variable delay in a range of 0 to 25 milliseconds. Eventide says this helps a doubled vocal sound more natural and less identical to the original take.

For doubling, the bundled H949 Dual plugin runs two H949 units in parallel, a setup the hardware was often used for to create doubling effects and stereo widening.

Reverse plays short signal segments back in time-reverse order. Combined with feedback around the reversed, delayed and pitch-changed segments, the developer says a wide range of new textures becomes possible.

Repeat captures incoming audio and can both time-reverse and pitch-change the captured material, which suits stutter and glitch-style effects.

The Flange mode produces the classic comb-filter sweep created when a signal with a varying delay is summed with a constant copy of itself. It is a useful addition for moving, metallic textures on vocals, guitars and synths.
