Behringer MS-1-BU
Behringer's MS-1-BU is a bright blue analog monosynth directly inspired by classic 1980s designs. With a look and sound that defined entire genres, it borrows the sound engine of one of the most sought-after analog synths from the 1980s—and now Behringer has brought it back and made it accessible to a new generation of musicians.
Using the same VCO and filter designs as the original, the MS-1 is true to the sound of the past; but it included expanded connectivity options and internal modulation routings that help it fit into modern workflows and the world's current soundscape. All of the original charm remains: the classic, intuitive sequencer—the guitar strap and mod grip for keytar-style use; and now, a built-in arpeggiator for extended melodic control and expanded options for filter modulation.
The MS-1 provides CV and gate and MIDI I/O for easy interfacing with modular gear, DAWs, and MIDI workstations, making it possible to bring the sound of countless dance and synth-pop classics into the workflows of any type of current musician.
