Behringer System 55's pots are standard, but users criticize the jacks, highlighting them as a weak point in the otherwise improved build quality.

Adding a fixed filter bank and sequencer to a Moog Matriarch can achieve sounds closer to the original System 55 setup, crucial for replicating Mort Garson's sound.

Users enhance their setup with additional 960 Sequential Controllers, 962 Sequential Switches, and 904A Low Pass Filters to expand functionality.

Moog Grandmother's CP3 mixer is crucial for achieving vintage Moog tones, more so than the filter, differentiating it from Behringer's offerings which lack this exact characteristic.

Moog Matriarch offers 49 keys with aftertouch and paraphonic options, making it superior for expanded patching and user experience compared to the Behringer System 55.

A workaround for the 921 glitch involves patching the output of the Aux into the clamping point, as explained in a detailed video walkthrough.

The Behringer System 55 may lack the presence and subtle grit evident in Moog synths, especially for users seeking the precise classic Moog sound.

Achieving '70s Moog sounds, users pair the System 55 with delay and reverb effects, seeking the distinctive modulated characteristics of older Moog modulars.

It's noted that Moog Grandmother's mixer distorts uniquely, providing an authentic Moog sound that Behringer struggles to replicate exactly.

Owners appreciate the modular nature, allowing parts to be exchanged after the warranty, mitigating concerns about durability.

The 921 oscillators may require calibration; owners use oscilloscopes to address periodic glitches in sine and triangle waves when switched to SUB mode.

Owners who bought the System 55 before the price drop still feel it offers unparalleled value, citing the ability to own a $35,000 Moog for a fraction of the price.
