Weโre big fans of Dexed, the free emulator of the Yamaha DX7. Weโve waxed on about it before so you may be wondering – โwhere do I buy this thing? It sounds fun.โ Well, the good news is that you donโt have to buy it – itโs completely free. Weโre going to share the steps to download, install and get started with your first Dexed sounds – letโs get behind the wheel!
The Dexed Download
When I first learned of Dexed, I thought โgreat, a free plug-in!โ, then, when I realized that you didnโt actually buy it, have an installer process, and company support, I thought โgreat, a free plugin!โ – LOL. The short story is that because Dexed is a free plug-in, there is no traditional infrastructure for installation, downloading, and authorization for the synth. Itโs slightly more involved than commercially sold plug-ins, but nothing you canโt handle.
The first step in the installation of Dexed is to head over to the github site where the Dexed versions are kept and maintained. Itโs located here (also stored for posterity in the Resources section at the end of this post):
Hereโs what youโll see at the Dexed landing page:

Dexed runs on OSX, Windows, and Linux, and has a separate installer for each. If you are on Mac or Windows, itโs easy – just click on the โMacโ or โPCโ icon in the upper right corner of the landing page to start the download. If you are on Linux, thereโs no button on the main page, unfortunately, so you will need to follow this link to the releases page, then download the latest version for Linux, which is named “***-lnx.zip”, where *** indicates the latest Dexed version number. Once youโve selected and dowloaded your version, simply un-zip it and weโre ready for our next steps!
A brief installation guide for each platform
Windows:
- Run the downloaded installer file.
- Follow the on-screen instructions to complete the installation process. You may need to specify the folder where you want Dexed to be installed.
- After the installation is complete, Dexed should be available in your DAW (Digital Audio Workstation) as a VST plugin.
MacOS:
- Double-clicking the .mpkg file will generate an error. Since Dexed is an open source project, thereโs no traditional โdeveloperโ and โsigned, identified developerโ process like those apps from the App Store. Once this error occurs, youโll need to go to โSettings > Privacy & Securityโ and scroll to the bottom of the window and click โOpen Anywayโ in order to proceed with the install.
- You can select Standalone, VST3, and AU installs – they are *really* small, so your best bet is just to install all three if you are not sure.
- Once installed, youโll need your DAW to scan the new plug-in and add Dexed to your list for use. You can also just launch the stand-alone version at this point.
Linux:
- Extract the downloaded archive to a folder of your choice.
- Make sure that the plugin file (usually with a .so extension) is executable. You can do this by right-clicking on the file, selecting “Properties,” and checking the “Allow executing file as program” option.
- Move the plugin file to the appropriate folder for VST plugins on your Linux distribution. This location may vary, so consult your DAW’s documentation or online resources for guidance.
First playback
Assuming you are a โquick gratificationโ person like me, letโs launch the stand-alone version of Dexed and check out some sounds. Double click the Dexed program icon and youโll see the main screen:

Youโll need to set up your MIDI input and Audio output in order to get that instant gratification, so click on the โOptionsโ button in the upper left corner of the window:

This screen will pop up, allowing you to select your Output for audio (External Headphones in my case – itโs early AM), as well as sample rate, audio buffer size and active MIDI input. In my case, Iโve selected the KL Essentiall 49 mk3 controller, and Iโm ready to go.
Once you close that window, youโll then be able to select and play sounds. Now, we have a lengthy tutorial already written about how to load new sounds here – but for now, letโs just select one of the default sounds that is loaded with the installation.
You may change sounds by clicking in the highlighted area of the main Dexed window:

Youโll then see a pop-up window showing all of the currently loaded โCartโ sounds.

wrapping up
THERE – itโs done! Weโve installed Dexed and checked out some new sounds. As mentioned previously, thereโs a SoundEngine.com article that highlights adding new sounds to Dexed here. Thereโs an entire universe of new sounds out there that you have not have in your arsenal. Donโt forget, either, that so far youโve auditioned sound in the stand-alone version. Once you load it into a track on your DAW, thereโs another level of sound design available once you add effects processing to the mighty FM generation synthesis available in Dexed.
We will be continuing our series on Dexed in the coming weeks – including generating custom CARTS, which is up next. Thanks for tuning in!
