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.

Plug a WM-1 into a keyboard, drum machine, or other hardware with standard MIDI I/O to wirelessly communicate with MIDI music apps on an iOS device and Mac computer, even at the same time. Or connect more instruments and devices with additional WM-1 units or the wm-1 Wireless MIDI Dongle. In addition to MIDI note data, you can send MIDI sync for tempo, effects, LFOs, loops, and more—all without connecting a single cable.
