DEX 3 LE version is ready for download (scroll down for download buttons).

As always, DEX 3 LE is freeware – so it’s completely free DJ software you can mix music with at your next house party or event. Yes, DEX 3 LE is free DJ mixing software that works on MAC or Windows that really whips the llama’s ass (shoutout to Nullsoft!🤛🏽).

The new DEX 3 LE release includes a few years of updates already found in our professional DEX 3 DJ software. While DEX 3 LE doesn’t include nearly all the “bells and whistles” found in DEX 3 Pro (audio/video/karaoke software), version includes improvements to the the file browser, a new audio engine with vastly improved sound quality, and a myriad of performance improvements. In short, DEX 3 LE received a long overdue under-the-hood tune up, ensuring it’s inline with our other DJ software products and that much more fun to DJ with.

Notable: With the newly refactored, modern and stable audio I/O system, DJs can now use up to three audio devices simultaneously. Example: if you have more than audio device with headphones connected the signal will be sent to/from all of them.
