Type.Drive.
Your keyboard becomes the throttle. Hold a rhythm, climb through the gears, and feel focused work gather momentum.
Download for MacIt feels driven because it is.
Redline reads cadence, not content. Your first keystroke starts the engine. Sustained flow earns higher gears. A pause eases the pedal instead of killing the momentum.
In the Mac app, every combustion pulse, exhaust resonance, shift, and overrun is synthesised live. There are no sampled RPM layers hiding underneath.
Type it. Hear it move.
Start the default cross-plane V8, then type at your natural pace. Your cadence—not the words—drives the needle and native engine sound.
Nothing typed here leaves this page. The demo decodes dense, unshifted operating points from Redline’s native synth with the shipping V8, cabin, Mac-speaker, space, width, and tone defaults.
15 engines.
From the thump of a single cylinder to the clean howl of a V12. Every layout has its own firing order, exhaust geometry, and voice.
Sound you can see.
The inner ring plots one complete engine cycle. Each mark is a real firing event, driven by the same crank angle that creates the sound in your headphones.
Your words stay yours.
Redline needs timing to feel your rhythm. It does not need—and cannot reconstruct—the words beneath your fingers.
Put an engine under your keyboard.
Try every engine for 2,000 words.
