How does the Yamaha DTX connect to a computer?
Through the USB TO HOST terminal, a USB-B socket that Yamaha's specifications list among the DTX402 module's connectors. Yamaha's own computer-connection guide says the standard drivers of Windows and macOS handle MIDI and that no other driver is needed; the Yamaha Steinberg USB Driver is only for audio over USB on Windows, which WebEDrums does not use. Yamaha's order of operations: switch the module off, connect the cable to USB TO HOST and then to the computer, then switch the module on; the cable should be a data cable under 3 metres.
The DTX-PRO module of the DTX6 series has the same kind of USB terminal, which Yamaha says sends and receives both MIDI and audio with a computer or smart device, plus a 5-pin MIDI OUT for hardware. Yamaha's DTX402 Touch app connects to the module by USB too; close it, and on Windows any other MIDI program, before opening the browser, since Windows gives a MIDI device to one program at a time.
Which preset do I pick in WebEDrums?
When the module's USB name contains Yamaha or DTX, the kit setup page offers "Use Yamaha defaults instead": the table below. The app's Yamaha preset follows Yamaha's DTX402 reference manual and differs from General MIDI in one detail, tom 2 on note 47 where General MIDI has 45. The guided setup gives the same result by listening to each pad, and is the better choice on a DTX6 whose trigger settings you have edited. Review each pad's lane, save, and change it later in Settings, Kit.
Which pads and zones does the Yamaha preset map?
This table is generated from the preset inside the app, so it is what WebEDrums listens for when you choose the Yamaha defaults. Several notes end up on one lane on purpose: the games have one red lane, not a head and a rim.
| Pad | Notes the preset listens for | Plays as |
|---|---|---|
| Kick | 36 head | Kick |
| Snare | 38 head · 40 rim · 37 cross-stick | Red (snare) |
| Hi-hat | 46 bow · 42 bow | Yellow cymbal |
| Tom 1 (high) | 48 head | Yellow tom |
| Tom 2 (mid) | 47 head | Blue tom |
| Floor tom | 43 head | Green tom |
| Crash | 49 bow | Green cymbal |
| Ride | 51 bow | Blue cymbal |
| Crash 2 (optional) | 83 bow | Green cymbal |
- Tom 2 is note 47 on Yamaha modules. The General MIDI preset treats 47 as the rim of tom 2, which lands on the same blue lane, so a module detected as generic still plays the toms correctly; the Yamaha defaults just list exactly what the module sends.
- Snare head, rim and cross-stick play red; the hi-hat's open and closed notes (46 and 42) play the yellow cymbal; a pedal-only chick is unmapped and therefore ignored.
- The DTX402 module has one crash input and one ride input (its connectors are SNARE, CRASH, HI-HAT CTL, KICK/PAD, TOM1 to TOM3, RIDE and HI-HAT), so the Crash 2 row only matters on a module with a second crash pad; skip it in the guided setup otherwise.
- A note outside the table is silent rather than an overhit, and a release sent as a zero-velocity note-on, which some Yamaha modules do, is treated as a release.
How do I keep the latency down?
The module's sounds are instant on its PHONES/OUTPUT jack. The DTX402 has an AUX IN mini-jack for a music player: feed the computer's headphone output into it and the song and the kit meet in your headphones with no software in between, the splitter diagram on the home page with the module as the mixer. The DTX-PRO can also receive the computer's audio over USB, which needs the Yamaha Steinberg USB Driver on Windows; a cable into AUX IN is simpler and needs none.
Turn on "Kit sounds in the browser" only when the module is muted or silent, then run the six-second calibration (eight clicks, hit the snare on each) so hits are judged against the delayed sound you actually hear.
What works in Chrome and Edge?
Chrome and Edge on Windows, macOS, Linux and ChromeOS. The module appears as a USB MIDI device under its Yamaha name after the one-time MIDI permission (Chrome has prompted for all MIDI access since version 124), and WebEDrums picks it as the drum input because the name matches. Firefox 108 and newer needs its site-permission add-on and forgets the songs folder between visits; Safari cannot talk to the kit. If the browser lists nothing, follow Yamaha's connection order once more, with a data cable and no hub, and make sure the DTX402 Touch app or a recording program is not holding the module on Windows.
Which games and apps read the Yamaha DTX?
Any of them that takes MIDI, since the module sends standard notes over USB. The setup differs per program: the Clone Hero drums setup and the YARG drums setup guides walk through the desktop games with the fixes for a kit that is not detected; the connection guide covers cables and drivers for all of them; and the comparison lays the apps side by side, WebEDrums included.
