The Frequency Central System X MU ADSR is a 5u adaptation of the iconic Roland System 100m envelope generator, the circuit which defined the “snap” those old Roland EG’s were so well known for.

This MU format version, provides two operating ranges and dual outputs providing both positive and negative voltages, there’s also manual triggering and a LED status light to see how you’re envelope voltages are responding to the incoming triggers.

At just a single unit wide, the module contains one of the most sought after envelope circuits around, which again (like the rest of the system x range) is very unique in the MU format.

The main features of the Frequency Central System X MU ADSR Include

• ADSR envelope generator based on the super snappy Roland System 100M
• Two response curves
• Dual outputs with positive and negative voltages
• Manual triggering
• 1 MU unit wide
