How to open DLS file?

An often recurring problem with Downloadable Sounds Format is that DLS is not associated with the correct program file. This causes the file DLS to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the DLS file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install SimpleSynth

An often overlooked issue is to make sure that SimpleSynth is installed on the computer. The easiest method is to use the system search engine by entering the program name SimpleSynth in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file DLS with SimpleSynth. Below you will find a list of applications that support DLS files.

Programs to open DLS file

Remember to download programs supporting DLS files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of SimpleSynth with DLS files

If the application is or has been freshly installed, but the DLS file still does not use the SimpleSynth program, it means no association. It is most convenient to call the context menu with the right mouse button and select Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. The "always use the selected program ..." field will set the SimpleSynth application as the default for handling the DLS file.

Step 3. Update SimpleSynth to the latest version

If, however, after binding SimpleSynth with Downloadable Sounds Format there were still problems, you should update the program to the latest version.

Step 4. Check for the following problems with the DLS file

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. Usually this applies to DLS files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the DLS file that we want to open. Sometimes virus-infected DLS files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the DLS files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged DLS files.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file DLS except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. The problem is only writing to the file, not reading it. Copying the DLS file to another location will fix the problem.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
