Title: Zoom H4 / Mac USB Problem

There could be a few potential causes for the issue you're experiencing with your H4 recorder and Cubase LE 4. Here are a few things you can try to resolve the problem:

1. Check the device driver: Make sure that the ZOOM H4 ASIO driver is properly installed on your computer. You may need to reinstall the driver if it has become corrupted or is not up to date.
2. Make sure the device is connected: Ensure that the H4 recorder is properly connected to your computer and that the connection is secure.
3. Restart the computer: Sometimes, simply restarting the computer can resolve issues with drivers or software.
4. Check the Cubase LE 4 settings: Make sure that the H4 recorder is selected as the input and output device in Cubase LE 4's preferences.
5. Check for updates: Check for updates for both Cubase LE 4 and the H4 recorder to ensure that you are using the latest version.
6. Disable other audio devices: If you have other audio devices connected to your computer, try disabling them to see if that resolves the problem.
7. Run Cubase LE 4 as administrator: Try running Cubase LE 4 as an administrator, by right-clicking on the Cubase icon and selecting "Run as administrator"
8. Check for conflicts: Make sure that there are no other software running that may be conflicting with the H4 recorder and Cubase LE 4, such as other audio recording software or system services that may be using the audio driver.

If none of these steps resolve the issue, it may be best to contact the manufacturer of the H4 recorder or Cubase LE 4 for further assistance. They may be able to provide additional troubleshooting steps or offer a solution to the problem.

You need to upgrade the H4  firmware from Zoom website

You will need an external SD card reader.
Good Luck

Sounds like it's time you upgrade to a core 2 or better computer.

Contact ZOOM ?

If you are using a Mac running Leopard (Sys 10.5), you need to upgrade the H4  firmware from Zoom website

Do you have an SD slot in your mac? plug the sd card there and see if it works. Erase manually the files (leave the system files) and try again with the H4. Luck

I may possibly have solved this. I didn't realise that when I log off from Cubase, the ASIO driver returns to the Multimedia ASIO driver, which seems to be the default setting.

Every time I want to record with the Zoom H4 in future I'll need to reconfigure the ASIO driver to the H4 one.

I thought once I'd set the driver, it would remain there every time Cubase booted up. Apparently not.

Hi Ken,
I'm sorry to hear that you're having trouble uploading the recordings from your Zoom H4 to the Cubase LE software. Have you tried connecting the Zoom H4 to your computer via USB and then importing the recordings directly into the Cubase LE program? You may also want to make sure that you have the latest version of the software installed on your computer, as well as the latest drivers for the Zoom H4. If you are still having difficulty, please don't hesitate to contact the Zoom or Cubase support teams for further assistance. I hope this helps!

I have just downloaded and installed the version 2.20 of the software for the H4 from the Zoom site. It solved my problem and the H4-SD card now shows up in the Finder as expected.

Note that I formatted a spare SD card to do this update in order not to lose any existing sound files.

Make the instalation of cubase LE that come when you buying the Zoom H4.When you instaled this,the driver H4 must appear in the sound/device properties.I hope you can solve
