The SYSTEM-1m takes the guesswork out of getting into modular with great sounds and the freedom to experiment right out of the box. And it can be played from any standard MIDI keyboard or receive MIDI messages from your DAW - just like you’d expect.

But the SYSTEM-1m goes way beyond standard synthesizer modules. With fully-lit, color coded patch points, you can experiment with reconfiguring its architecture and easily connect to a wide world of available synthesizer modules. In addition to functioning as a rackmount or tabletop unit, the SYSTEM-1m can be mounted in a standard Eurorack case and can be powered via integrated case power with the included adapter cable. Its versatile synth architecture integrates beautifully with existing modular setups - or it can be the heart of a burgeoning modular synthesizer rig.

PLUG-OUT synthesizers use Roland's Analog Circuit Behavior technology to perfectly replicate some of their most revered classics. They work like regular VST or AU compatible plugins in a DAW, with the SYSTEM-1m’s array of high-resolution knobs and sliders creating an elegant, one-to-one control surface that works seamlessly. But you can also load PLUG-OUT synths directly into the SYSTEM-1m and switch between the internal synthesizer architecture and one of a growing number of PLUG-OUT Roland classics, like the SH-101, SH-2 and PROMARS - with no computer required!

In addition to being a powerful standalone instrument, the SYSTEM-1m has external inputs and an array of CV/Gate connections that allow it to be re-patched and to interface with other modular synthesizer systems. The SYSTEM-1m’s CV/Gate connections combined with its ability to load classic Roland PLUG-OUT synth models like the SH-101 and PROMARS give it power and flexibility that is simply unparalleled.

Roland synth


So much fun right here. People cannot keep their hands off of this, not only because it is fun but because it sounds incredible. Usually something that gets "shopworn"like this ends up breaking down, but this has proven to be diehard Lee @ Sam Ash Cincinnati

The System 1 In Rack Form


Now you can take the Roland System 1 and operate it with any controller. Mount it in a rack and take it on the road or have it receive MIDI triggers from your DAW. Probably the best sound synth module at this price point, it delivers a solid mix of old school and new school sounds. Great for hip hop, electronic, industrial and rock bands.
