Drum Pad
Eight synthesised drums on pads and keys — kick, snare, hats, cowbell.
About this pad
Eight pads, eight classic drum voices, zero samples: every hit is synthesised the instant you strike — keys QWER and ASDF map the two rows, pads take taps and clicks, and it's fully polyphonic, so flams and simultaneous hits land naturally.
How drums are built from math
These are the recipes analogue drum machines made famous: the kick is a sine wave diving in pitch (150→45 Hz in a tenth of a second); the snare is filtered noise over a 190 Hz thump; hats are high-passed noise, short for closed and ringing for open; toms are pitch-bending tones; the clap is three noise bursts milliseconds apart (a crowd, not a hand); and the cowbell — famously — is two detuned square waves, exactly as the 808 built it. Synthesis beats samples here for latency (nothing to load) and for honesty: you can read this page and know precisely what your ears get. Practice angle: put the metronome underneath and drill eighth-note hats with backbeat snare — the pattern under most of pop — or find a song's tempo with the BPM counter and play along. The piano completes the two-tool band.
Frequently asked questions
What keys play the drums?
Top row Q-W-E-R: kick, snare, clap, cowbell. Home row A-S-D-F: closed hat, open hat, low tom, high tom. Multiple keys at once work — it's fully polyphonic.
Why synthesised instead of real drum samples?
Instant response (nothing downloads), classic character (these are the 808-family recipes), and zero licensing murk. The cowbell really is two detuned square waves — that's the authentic recipe.
Can I record my beats?
The pad itself doesn't record — pair it with the voice recorder tool capturing your speaker, or a proper DAW when the beat deserves it.
Why is there latency on Bluetooth headphones?
Bluetooth audio adds 100-300 ms of its own — wired output or speakers restore the instant feel. The synthesis itself is effectively instantaneous.
