‌ 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 as much as possible. Wireless controls should be easy to set up and just as sensitive and reliable as cable connection. Join the wireless MIDI revolution with the Roland WM series, where your creativity knows no bounds.

Connect the WM-1 to a keyboard, drum machine, or other hardware with standard MIDI connectors to wirelessly communicate with MIDI music apps on your iOS device and Mac, even at the same time. Or connect more instruments and devices with additional WM-1 units or WM-1D wireless dongle. In addition to MIDI data, you can send MIDI sync for tempo, effects, LFO, loops and more - all without any cables.

Basic Properties

Wireless MIDI adapter for keyboards, drum machines and other MIDI devices

Available WM-1D Wireless MIDI dongle provides wireless MIDI for Windows computers and support for Fast mode for macOS and iOS

Unleash your creativity.

There are situations where wireless MIDI can actually fix the problem. You may need a simple, clean setup with a MIDI keyboard and laptop, iPhone or iPad. Or you might have your favorite MIDI controller located away from your DAW that requires long, unsightly cables to trip over. Or maybe you just want the freedom to move around your creative space with a tiny keyboard or controller. Intricate setups kill creativity - and once you've experienced Roland's simple wireless MIDI interface, you'll never want to go back.

Low latency. High performance.

For musicians, the failure of many wireless MIDI systems is latency - that is, the time it takes to hear a sound when you press a key or hit a drum pad. The high latency makes playing feel unnatural and you can never get the timing right. Our proprietary wireless technology in the WM series provides an instant, ultra-fast playing experience as if you were connected via a regular MIDI cable.

Critical speed.

While the standard mode in WM-1 / WM-1D will cover most gaming situations, time-critical applications can benefit from even greater speed. Fast mode boosts transfer speeds up to 3ms - better than the internal speed of many devices - providing ultra-fast communication with WM-1 or WM-1D among others.

WM-1D: computer support and ultra-low latency.

If you are using a Windows computer, you need a WM-1D dongle to add a wireless MIDI interface to your setup. This is what you need. Just plug it into a free USB port for smooth and responsive communication with any instrument or device on the WM wireless system. Mac computers and iOS devices can communicate with the WM series device in Standard mode via Bluetooth MIDI. However, if you need the benefits of Quick Mode or want to wirelessly connect multiple computers, simply plug in the WM-1D. *
