iPads with a Lightning port need a powered USB adapter to run a drum module. Use the genuine Apple Lightning to USB 3 Camera Adapter — the model with a second Lightning port — and plug a charger into that power port.

Cheap third-party Lightning-to-USB adapters usually can’t deliver enough power for a module such as the Alesis Nitro Max: the kit simply never appears, even though the adapter looks identical.

Connect the module’s USB cable using a USB-C adapter or a USB-C to USB-B data cable. Charge-only cables are a common cause of a kit silently not appearing — the cable fits, but no data flows.

If the module still isn’t detected, try a powered USB hub: some modules need more power than the device port alone provides.

Check, in order:

1. The module is powered on.
2. The USB cable is a data cable and firmly seated at both ends.
3. Open the MIDI setup inside iQuantize — most class-compliant kits are recognized automatically, and a kit is remembered once mapped.
4. Still nothing? Unplug and replug the cable, then restart the app.

On an iPad with a Lightning port, a powered genuine Apple adapter is required — see the Lightning case.

iQuantize applies an automatic pad mapping for Roland, Yamaha, Alesis, EFNOTE, Simmons, and 2box modules. If your module isn’t recognized — or it uses a custom kit layout — some pads can land on the wrong drums.

Open the in-app MIDI setup and use the learn mode: hit each pad and assign it. The mapping is saved per device and restored automatically the next time you connect that kit.

Check the output device and volume in Settings → Audio inside the app, then the system volume and mute state.

Note that chart playback and drum monitoring come from your iPhone, iPad, or Mac — the drum module’s own headphone output only plays the module’s internal sounds.

Bluetooth headphones and speakers add noticeable delay — often 100 ms or more — which makes tight drumming feel impossible. For monitoring, use wired headphones or wired speakers.

Alternatively, monitor your own drums through the module’s headphone output, which is instant, while the app plays the backing chart.

Double and missed triggers are almost always module-side sensitivity settings. In your module’s pad settings, lower the sensitivity or raise the threshold for pads that double-fire, and raise the sensitivity if soft ghost notes are dropped. Your module’s manual covers per-pad sensitivity, threshold, and crosstalk.

iQuantize scores exactly what the module sends, so clean triggering matters.

If the module reacts to the hit but the note never appears in the app, the strike was fine and the link between them was not. Try a different USB cable first — a charge-only cable looks identical to a data one — then connect the module directly rather than through a hub, dock or monitor port.

Calibrate the hi-hat pedal on your module. iQuantize distinguishes open, closed, and pedal hi-hat, and maps half-open articulations to the nearest of those targets.

If open and closed still feel reversed or stuck, recalibrate the pedal in the module settings and check the pedal cable.
