Got a Fingersonic Keys MIDI keyboard or a Fingersonic Beats drum machine? Both devices ship with a free, browser-based Firmware Updater that flashes the latest firmware in minutes — no desktop app, no driver install, no account required.
This guide covers both updaters in one place, points you to the right URL for your device, walks through the four-step flashing process, and explains the recommended browser setup for the smoothest experience.
Fingersonic ships a separate updater for each product. Pick the one that matches your device:
Pocket-sized MIDI keyboard with BLE/USB output, customizable sounds, RGB LED keys, and built-in speaker.
👉 Open Keys UpdaterPortable drum machine and pad controller with velocity-sensitive pads, built-in sounds, and USB-MIDI.
👉 Open Beats UpdaterThe two updaters look and behave almost identically — the only difference is the device-specific gesture to enter bootloader mode (covered in Step 2 below). Both run in any modern browser; both talk to your device over its own Wi-Fi hotspot.

The Fingersonic Firmware Updater is a lightweight web tool hosted at update.fingersonic.cn. It works directly in your browser and talks to your Fingersonic device over the device's built-in Wi-Fi hotspot. There is nothing to install.
To run an update you need:
The Keys updater also supports a Continuous Burning toggle for batch-updating multiple units without re-clicking the button between devices.
For the smoothest experience, we strongly recommend using Safari on iPhone, iPad, or macOS. Here's why Safari is the best match for the updater:
Chrome on macOS also works well as a backup. Avoid private/incognito windows — cached firmware won't survive a tab restart.
The four steps are nearly identical for both devices. The only difference is the bootloader gesture in Step 2.
Plug in your Fingersonic Keys or Fingersonic Beats and make sure the battery is at or near full. A power loss during flashing can permanently damage the device. Check the box "I have confirmed the device has sufficient battery" to unlock the next step.
⚠️ Important: Do not unplug or power off the device while flashing is in progress.
This is the only step that differs between the two products. Pick the matching instruction below.
For Fingersonic Keys:
For Fingersonic Beats:
Check the box "LEDs blinked — I'm in bootloader mode" in the updater to continue.
The Fingersonic Keys or Beats broadcasts its own Wi-Fi network while in bootloader mode.
Fingersonic.88888888 (eight 8s).Once connected, return to the updater tab and check "I'm connected to the Fingersonic hotspot". Safari will reload the page on the new network — this is normal, and your progress is preserved.
Click the Upload Firmware button. The updater will:
The whole process typically takes 1–3 minutes. Once the Fingersonic Keys or Beats reboots and reconnects, the new firmware is live.
If you're a retailer, classroom, or have multiple Fingersonic Keys units, toggle on Continuous Burning at the bottom of the Keys updater. After each successful flash, the tool automatically scans for the next device — when it detects one, the Upload button re-enables so you can flash again without reloading.
This is expected on iPhone — Safari drops the main internet connection when it joins a hotspot that has no internet uplink. The updater detects this and reloads itself automatically. If it doesn't, tap the URL bar and reload manually.
Make sure you've checked both Step 1 and Step 2 boxes. The updater enforces sequential steps to prevent partial flashes.
Move closer to the Fingersonic device (within 1–2 meters). The Wi-Fi signal between the device and your phone is the bottleneck, not your internet speed.
Wait at least 60 seconds. If nothing happens, long-press the power button for 10 seconds to force a reboot — the firmware will still be applied.
Firmware updates keep your Fingersonic Keys and Beats performing at their best:
Whether you play a Fingersonic Keys MIDI keyboard or a Fingersonic Beats drum machine, keeping the firmware fresh is the single best way to ensure the best playing experience — tighter MIDI response, new sound packs, and ongoing bug fixes. With the free web updaters and a Safari browser, you're four checkbox clicks away from the latest features on either device.
