If you hit on the beat but hear the song — or your score — a little behind, something between the computer and your ears is adding delay. It is rarely the kit: the USB MIDI message is almost instant.
The usual cause: the speaker
Bluetooth speakers and headphones add a noticeable delay, often a tenth of a second or more. The music reaches you late, so you play late to match it.
How to fix it
- Use wired headphones or speakers on the computer's own output. This removes most of the delay.
- Calibrate. In DRUMY's pause menu, run Tap along with the click: hit a pad on each click, and the game learns how late your sound is and allows for it.
- Close other audio apps that might be processing the sound.
Then play a song again: the judgement of each hit should match what you feel.
