Connect your Donner DP-20 to your computer using a USB cable

The Donner DP-20 is a digital piano that stores recordings internally. To move those recordings to your computer, you connect the piano to your computer with a standard USB cable (usually USB-A to USB-B), then access the files through your computer's file manager. The piano will appear as a removable storage device, similar to a flash drive.

Plug the USB cable into the USB port on the back of the DP-20 and into an available USB port on your computer. Wait about 5 to 10 seconds for your computer to recognize the device. On Windows, you may see a notification in the taskbar. On Mac, the piano should appear on your desktop or in Finder.

If your computer does not recognize the device, try a different USB port or a different cable. Some cables are charge-only and do not transfer data. If you still have no luck, check the Donner website to see if your operating system needs a driver—though most modern computers recognize the DP-20 without one.

Key Takeaways

  • The Donner DP-20 connects to your computer via USB cable and shows up as a removable storage device.
  • Recordings are stored in a folder called MUSIC or RECORDINGS on the piano's internal memory.
  • You can copy the audio files directly to your computer using your file manager—no special software is required.
  • Audio files from the DP-20 are usually in WAV format, which works with any media player or audio editing software.

Locate the MUSIC folder on the DP-20

Once the piano is connected and recognized, open your file manager (File Explorer on Windows, Finder on Mac). Look for the DP-20 in the list of devices or drives. Double-click it to open the piano's storage.

Inside, you should see a folder labeled MUSIC or RECORDINGS. This is where the DP-20 stores all the pieces you have recorded. Open this folder to see the individual audio files. Each recording is usually named with a number or date, depending on how your piano is set up.

If you do not see a MUSIC folder, check whether the piano has any recordings saved. If you have never recorded anything on the DP-20, the folder may not exist yet. Record a short test piece on the piano, reconnect it to your computer, and the folder should appear.

Copy the audio files to your computer

Select the audio files you want to transfer. You can click one file, or hold Ctrl (Windows) or Command (Mac) and click multiple files to select them all at once. Right-click and choose Copy, or use Ctrl+C (Windows) or Command+C (Mac).

Navigate to the folder on your computer where you want to store the music—your Documents folder, a Music folder, or anywhere else you prefer. Right-click in the empty space and choose Paste, or use Ctrl+V (Windows) or Command+V (Mac). The files will copy over. Depending on the file size, this may take a few seconds to a minute.

Do not unplug the USB cable while the files are copying. Wait until the progress bar finishes and the files appear in your destination folder before disconnecting the piano.

Understand the audio file format

The Donner DP-20 records in WAV format, which is a standard uncompressed audio file. WAV files are larger than MP3 files but preserve the full quality of your recording. Any media player on your computer—Windows Media Player, iTunes, VLC, or your web browser—can play WAV files without any conversion.

If you want to convert the files to MP3 (which takes up less space) or edit them, you can use free software like Audacity or online converters. But conversion is optional; WAV files work with everything out of the box.

Safely disconnect the DP-20

After the files have finished copying, safely eject the piano from your computer. On Windows, right-click the DP-20 in File Explorer and select Eject. On Mac, click the eject icon next to the DP-20 in Finder. Wait for the confirmation that it is safe to remove, then unplug the USB cable.

Ejecting properly prevents file corruption and protects both your computer and the piano. If you unplug without ejecting, you risk losing data or damaging the piano's storage.

Troubleshoot common transfer problems

The piano does not show up on my computer. Try a different USB port and a different cable. Some cables are designed for charging only and do not carry data. If the piano still does not appear, restart your computer and try again. Check the Donner support page to see if your Windows or Mac version needs a specific driver.

The files copy but will not play. Make sure you are using a media player that supports WAV files. Most do, but if you are using an older or limited player, try VLC (free, works on all systems) or your computer's built-in media player. If the file plays but sounds corrupted, the recording itself may have been damaged on the piano; try re-recording.

The transfer is very slow. USB 2.0 connections are slower than USB 3.0. If your computer and cable support USB 3.0, use a USB 3.0 port (usually blue inside). Also, close other programs that are using your hard drive, as this can slow the copy process.

Organize and back up your recordings

Once your files are on your computer, create a dedicated folder for your piano recordings so they are straightforward to find later. You might organize them by date, by piece name, or by practice session. Give each file a descriptive name instead of leaving it as a number.

Consider backing up your recordings to an external hard drive or cloud storage (Google Drive, Dropbox, OneDrive). This protects your work in case your computer fails. Many cloud services offer free storage for a reasonable number of files, and external hard drives are inexpensive.

Frequently Asked Questions

Do I need special software to transfer files from the DP-20?

No. The piano appears as a standard storage device, so you can use your computer's built-in file manager to copy files. No drivers or special programs are required on most computers.

Can I transfer files wirelessly from the DP-20?

The Donner DP-20 does not have Bluetooth or Wi-Fi file transfer. You must use a USB cable to move recordings to your computer.

What happens to the recordings on the piano after I copy them?

The files remain on the piano's internal memory. Copying them to your computer does not delete them from the piano. You can delete them manually from the piano if you want to free up space.

Can I edit the WAV files I transfer?

Yes. Free software like Audacity lets you trim, adjust volume, add effects, or export to other formats. You can also use any audio editing software that handles WAV files.

How much storage space do recordings take up?

A one-minute recording in WAV format is roughly 10 to 12 megabytes. A five-minute piece takes about 50 to 60 megabytes. Most computers have plenty of space for dozens of piano recordings.
