BUILT FOR PADS, NOT PLASTIC GUITARS

Every drum gets its own track. Hi-hats show open and closed symbols, the three toms share one lane, and the crash slams across the whole highway.

FOUR DIFFICULTIES

Easy, medium, hard, expert. Chart only the expert part and the easier versions are generated with musical rules: ghost notes go first, hats thin out, fills collapse to their last hit.

REAL SCORING

Perfect / great / good windows, a 4× combo multiplier, overhit penalties, star ratings, full-combo badges and a local leaderboard for every song and difficulty.

PRACTICE MODE

Slow the song to 50%, loop a section with A/B points, seek around, and turn on guide drums to hear the part. Practice never touches your scores.

YOUR KIT, YOUR SOUND

A punchy synthesized drum kit is built in, so there is nothing to download. Any song can ship its own samples per drum, or you can let your FGDP make the noise.

PAD SETUP WIZARD

Hit the pad for kick, snare, toms, hats, ride, crash. Assign several pads to one drum. Saved per device, with presets for the FGDP-30/50 and generic 4×4 controllers.

LATENCY CALIBRATION

A twelve-click test measures how late your hits land and dials in the offset automatically. Hit timing is stamped by the MIDI driver, not by the frame rate.

SCREENS

MAKE A SONG IN FIVE MINUTES

The Studio turns a performance into a chart. No DAW required, but the output is standard MIDI if you want to polish it in one.

Load a drum-less mixmp3, wav, flac, aac, m4a or ogg. Tap the tempo, then hit a pad on the first downbeat to set the offset.

Record a takeCount-in, metronome, and every pad hit captured with velocity while the highway carves your chart behind you.

Quantize1/4 to 1/32, triplets, adjustable strength and swing. Preview with the song and your drums.

Save & shareSave as any difficulty, export the MIDI, or download the whole song as a zip. Drop it in a friend's song list.
