Key Features

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. For connection to a Windows PC you will also require a Roland WM-1D Wireless MIDI Dongle (available separately).

Best in class low-latency in standard mode and Fast mode delivers ultra-low-latency communication (3 ms) for timing-critical applications (Fast mode requires a Roland WM-1D Wireless MIDI Dongle – available separately – connected to a macOS/iOS/iPadOS device).

Easy to set up, and just as responsive and reliable as plugging in a MIDI cable.

Make music whenever and wherever you want, eliminating cables and clutter.

In addition to MIDI note data, you can send MIDI sync for tempo, effects, LFOs, loops, and more—all without connecting a single cable.

Also provides MIDI communication between other WM-series units & macOS/iOS Bluetooth MIDI devices. Standard mode supports up to four total devices; Fast mode supports two total devices.

Runs for about 60 hours on a single AAA battery.

Optional WM-1D Wireless MIDI Dongle provides wireless MIDI for Windows computers and Fast mode support for macOS & iOS. N.B. You will need a WM-1D if you want to connect to a Windows PC.

Pros & Cons

👍 Pros

  • Enables wireless MIDI communication for instruments with standard MIDI I/O to iOS devices and Mac computers simultaneously.
  • Features best-in-class low-latency in standard mode and ultra-low-latency (3 ms) in Fast mode for timing-critical applications.
  • Offers an easy setup process, designed to be as responsive and reliable as a traditional MIDI cable connection.
  • Eliminates the need for physical cables, helping to reduce clutter and create a more flexible music production environment.
  • Capable of transmitting not only MIDI note data but also MIDI sync for tempo, effects, LFOs, and loops wirelessly.

👎 Cons

  • To connect to a Windows PC, a separate Roland WM-1D Wireless MIDI Dongle is required, adding to the overall cost and complexity.
  • Achieving ultra-low-latency Fast mode also necessitates the purchase of a Roland WM-1D Wireless MIDI Dongle for macOS/iOS/iPadOS devices.
  • Standard mode supports a maximum of four total devices, which might be a limitation for larger, more complex wireless MIDI setups.
  • Fast mode has a further limitation, supporting only two total devices, which could restrict simultaneous use of multiple instruments with critical timing.
  • The adaptor runs on a single AAA battery, requiring periodic replacement, though it offers about 60 hours of operation.
