SKRATCH ATTACH (The Tonearm System) by Retrobionic

What is the Skratch Attach System?

Published on September 6, 2025 – Updated April 5th, 2026

If you own a Rane One, Rane Twelve, or Hercules T7 and want to add a real tonearm for authentic vinyl playback, the Skratch Attach X10 by Retro Bionic is the system built for exactly that. Compatible with the Rane One MK1 and MK2, Rane Twelve, and Hercules T7, it’s the only removable tonearm system that works across multiple motorized DJ controllers without permanent modification.

Meet the Game-Changing Tone Arm System

The Skratch Attach system is an innovative DJ accessory developed by Retro Bionic that bridges the gap between analog and digital DJing. The system consists of motorized DJ controller-compatible turntable arms and accompanying software that allows DJs to play real vinyl records on modern motorized DJ controllers.

Core Components That Make the Magic Happen

The X10 Tonearm

The centerpiece of the system is the X10 tonearm, which magnetically attaches to compatible motorized DJ controllers and is fully extendable. This ingenious design allows the tonearm to accommodate various record sizes, including 7-inch, 10-inch, and 12-inch vinyl records. The X10 tonearms retail for $225 each from RetroBionic.

The X10 is currently the only removable, no-adhesive tonearm option available for the Rane One MK1 and MK2.

Versatile Compatibility

Don’t worry about being locked into one controller brand. The Skratch Attach system currently works with several popular DJ controllers, including the Rane Twelves, Rane One, and Hercules T7. When fully extended, the X10 can be used with the Rane Twelve and provides stability perfect for mixing and scratching, while the shortest setting works with the Rane One, creating an ideal portable vinyl setup for 45 RPM records.

The Skratch Attach app now supports iOS, MacOS & Windows which opens more possibilities for a compact setup for vinyl DJ’s.

Getting Set Up: What You’ll Need

To function properly, the system requires Skratch Attach software and a compatible DJ controller such as the Rane Twelve or Rane One. The Hercules T7 is another controller but requires an audio interface, such as the Denon D1S. This setup enables the controller to process analog audio signals from the vinyl records while maintaining digital control capabilities. It’s surprisingly straightforward to get up and running, making this accessible even for DJs who aren’t tech wizards.

The Story Behind the Innovation

The product emerged as a labor of love from Retro Bionic, inspired by Biz Markie’s 7-inch Technics setup, with the goal of making similar vinyl-playing functionality accessible to more DJs. It’s refreshing to see a company create something purely out of passion for the art form rather than just chasing market trends.

The system is particularly appealing for DJs who want to incorporate real vinyl into their performances without investing in traditional turntables or dealing with the bulk and maintenance they require.

Why This Matters for Modern DJ’s

The Hercules T7 compatibility is especially noteworthy, as it potentially offers a more affordable solution than traditional turntables for spinning 7-inch singles. This makes the Skratch Attach system an attractive option for DJs seeking authentic vinyl manipulation capabilities while maintaining the convenience and features of modern digital DJ controllers.

The Rane One MK1 & MK2 platforms are fully supported by the Skratch More Mounts and Skratch Attach software.

Another contender for use with the Skratch Attach system is the Rane Twelve digital turntable. Skratch Attach turns it into a hybrid turntable for digital and analog use.

This simply means more options for DJ’s to use the Skratch Attach system and get even more value out of their controller(s).

Whether you’re a bedroom DJ looking to expand your setup or a professional seeking more creative possibilities, this system opens up new avenues for expression without breaking the bank or requiring a complete equipment overhaul.

The Bottom Line

The Skratch Attach system represents a unique approach to hybrid DJing, allowing performers to experience the tactile feel and authentic sound of vinyl records while leveraging the advanced features and portability of contemporary DJ controllers. It’s not just about nostalgia—it’s about expanding creative possibilities in an era where flexibility and innovation drive the best performances.

For DJs ready to bridge the gap between past and present, the Skratch Attach system offers a compelling solution that honors vinyl’s legacy while embracing digital convenience.
