Tools for tango DJs
The same engineering background that shapes the sets also builds the tools behind them — software made by a working DJ, for working DJs. Everything here exists to put better musical decisions and cleaner sound on the floor.
El Eje — the player
A macOS music player built for tango: orchestra- and singer-aware library, key and tempo detection, per-track EQ, tanda building, and synced lyrics. Designed around the realities of a milonga, not a club.
El Eje for Chrome
Carry your tango library onto the web, fully offline: look up any recording — orchestra, singer, year, key, BPM, lyrics with translation — in a side panel, and follow lyrics along on YouTube.
Tanda Builder
Assemble and audition tandas by orchestra, era, and energy — a fast way to plan the arc of a night and keep your sets consistent.
EQ Lab
Hear what equalization does to a transfer before you commit. Shape the spectrum for the room and learn the why behind every move.
Equalization & sound
A practical guide to balancing tango recordings across frequencies for clarity on a real sound system — the theory behind the EQ lab.
