Roland WM-1D MIDI Wireless System


Wireless MIDI for a wireless world.

In today's world, you need the ability to make music whenever and wherever you want, eliminating cables and clutter however possible. And wireless control should be easy to set up and just as responsive and reliable as plugging in a cable. Join the wireless MIDI revolution with the Roland WM series, where your creativity knows no bounds.

If you're using a Windows computer, the WM-1D is what you need to bring wireless MIDI into your setup. Simply plug it into an open USB port for low-latency communication with any instrument or device equipped with a WM-1/WM-1D unit, or with iOS devices and Mac computers via Bluetooth MIDI. In addition to MIDI note data, you can send MIDI sync for tempo, effects, LFOs, loops, and more—all without connecting a single cable.

iOS devices and Mac computers can smoothly communicate with a WM-series unit in Standard mode over Bluetooth. But in situations where you need the fastest transfer speed possible, just add a WM-1D.
