TurboBeast is an engine you play: a drift synth with a gas pedal instead of a keyboard. Every rev is synthesized live from a combustion pulse train -- no samples, no loops. Pick a machine, start the engine, and drive the sound: squeeze the gas, stab the brake, bang through the gears, and slide the rear end until the tires sing. SIX MACHINES - 2ST RACER -- ringing two-stroke bike - SUPERSPORT -- screaming inline-four - CRUISER -- lazy V-twin thump - DRIFT SEDAN -- turbo four built to slide - ROTARY COUPE -- high-strung rotary - V8 MUSCLE -- heavy eight-cylinder rumble REAL DRIVING CONTROLS - ENGINE START, gas pedal with LATCH, brake and steering - Sequential or H-pattern shifting, gears 1-6 with real ratios - Gas + brake together breaks the rear loose: drift, tire squeal, backfire - Rev limiter stutter when you pin it SET THE SCENE - 6 tires x 5 road surfaces x 4 exhausts x 4 stages (highway overpass echo, local street, rural road, warehouse) - SUB layer for chest-deep low end, adjustable brake BITE and FADE PLAY IT LIKE AN INSTRUMENT - MIDI notes pitch the engine, so you can write riffs with it - 12 ready-made MIDI controller maps, pitch bend rides the gas - Works as an AUv3 plugin in GarageBand, Logic Pro, AUM, Cubasis and more - A guided first-launch tour points at the controls that matter FREE VERSION Free to drive: 2ST RACER and DRIFT SEDAN with every control, every tire, road, exhaust and stage. TURBOBEAST PRO -- ONE-TIME PURCHASE, NO SUBSCRIPTION - All six machines - Record, export and share your runs For iPhone, iPad and Mac. One Pro purchase unlocks all three.

Verdict
The clearest difference is in-app purchases: iRetroMuse at none against TurboBeast's 1. TurboBeast's advantage is ads (none vs shown) and device support (4 vs 2). On price and update cadence there is nothing between them.
