柠檬打鼓 is a free iPhone app developed by 军 田 that allows you to connect your electronic drums to your iPhone and enjoy playing anytime, anywhere. With the app, you can turn your iPhone into a music source for your electronic drum kit.

To connect your electronic drums to your iPhone, you will need an official Apple Lightning to USB Camera Adapter and a standard 1-meter USB printer cable (less than 1.5 meters to avoid latency). Simply plug one end of the printer cable into the USB port of your electronic drum module and the other end into the USB port of the Lightning to USB Camera Adapter. Then, connect the Camera Adapter to your iPhone.

Once the USB connection is established, make sure to turn on your electronic drum module first and wait for it to fully initialize before opening the 柠檬打鼓 app on your iPhone. If the sequence is reversed, the app may not recognize the drumming signals. In such cases, simply close the app, turn off the drum module, and restart in the correct order.

For users with HXM Red Devil Electronic Drums 008X, 450 series, and higher models, there is also the option of wireless Bluetooth connectivity with the 柠檬打鼓 app on your iPhone. To set up Bluetooth pairing, open the 柠檬打鼓 app on your iPhone, go to the settings on the home page, and select the Bluetooth pairing function. Pair your iPhone with the HXM electronic drum module (not the regular Bluetooth pairing on your iPhone for audio services), and you can enjoy wireless drumming without the need for cables.

With 柠檬打鼓, you can conveniently connect your electronic drums to your iPhone and explore a wide range of drumming features and functionalities. Whether you're a beginner or an experienced drummer, this app provides a seamless and portable drumming experience.
