Once these are done this card goes away.
Notation follows the Percussive Arts Society standard: cymbals are x noteheads, drums are round; bass drum sits in the first space, snare in the third, toms above it, ride on the top line, hi-hat above the staff, crash on the ledger line, foot hi-hat below the staff. o = open hi-hat, + = closed, > = accent, ( ) = ghost note, R/L = sticking. Counts read 1 e & a.
Library
Pattern editor
Sixteenth-note grid in 4/4, up to eight bars. Click a cell for a note, again for an accent (>), again for a ghost note ( ), again to clear. Arrow keys move, space cycles, R or L types the sticking. Saved patterns appear under My patterns and live in this browser; Export writes them to a file you can import elsewhere.
Connection
Last note: –
space bass drum, J snare, F closed hi-hat, G open hi-hat, D foot hi-hat, R T Y toms, U crash, I ride. With a kit connected and the keyboard kit off, space starts and stops, Esc stops.
Sound
Playback performs the pattern through the built-in kit, or through the module's own sounds when it is chosen above (the page sends it MIDI). At zero click volume you practise against a silent beat and are still graded.
Timing
Plays quarter notes on the snare; the report then offers your mean offset as the latency offset, which removes the module's and the USB chain's delay from every score.
Runs the metronome for eight bars. Raise the offset when the beat flash comes before the click (usual with Bluetooth), lower it when the click comes first. Display only; scoring is unaffected. Browser reports: –.
Pads
Click a pad, then hit it on the kit to learn its MIDI note. Defaults are the Alesis Nitro factory map. Open/closed hi-hat from: note number · pedal: no controller data yet. If the module sends one note for both hi-hats, learn both to that note and the pedal (controller 4) decides: pressed = closed.
Appearance
Skins change colours, decoration and the words on the buttons and in the scores. Notation, thresholds and grading do not change.
