Inspired by vintage Roland modular synths of the 1970s, these new additions to the SYSTEM-500 family not only expand on the SYSTEM-100m-based modules, but also explore fresh territory. Designed in Eurorack format, the SYSTEM-500 delivers the classic character and functionality of vintage Roland modular synths, with all the advantages of a modern instrument. The SYSTEM-500 is made to exacting standards in a collaborative design and production process between Malekko in Portland, USA and Roland in Hamamatsu, Japan.

Inspired by the SYSTEM-100m’s 131 output module, the SYS-531 brings an updated approach with convenient and modern features. With six high-quality inputs, each with level slider, pan knob, and performance-friendly mute button, the SYS-531 is your central hub for mixing mono or stereo (PRE only) signals. It has high-fidelity sound with low noise, ensuring that your modular rig sounds its best. The six pan knobs are CV controlled so you can create space and dimension, and achieve interesting stereo effects. There’s even a boutique-quality stereo preamp, so you can bring in mic or line level signals –and abusing this preamp’s gain knob gives you pleasing overdriven tones. The headphone section has an easy-to-reach, dedicated volume knob as does the multi-format output section that lets you use both 1/4”and 1/8” cables. There’s even an LED level indicator for visual feedback.
