The Ultimate Support MDS-X Expander for MDS-100 is a small modular connector piece designed to link two MDS-100 desktop stands together and turn them into a two-tier studio setup.

It’s part of the Ultimate Support MDS-100 Modular Desktop Stand system, mainly used for synths, drum machines, controllers, and audio gear.

What it actually does

• Connects two MDS-100 stands into a stacked configuration
• Lets you build a second level (2-tier rig) for more gear in less desk space
• Improves ergonomics and access to knobs and controls
• Adds a bit of structural stability when stacking the system

Key specs

• Material: glass/polymer/plastic composite
• Weight: ~0.6 lb (very lightweight)
• Function: mechanical connector (not a stand itself)
• Setup: requires 2× MDS-100 stands to work properly
  

Why people use it

If you’re running a compact studio setup, this expander is basically a way to:

• stack gear vertically instead of spreading it across the desk
• keep synths/effects within easier reach
• create a cleaner “rack-like” workflow without buying a full rack system
