Roland WM-1D USB Wireless MIDI Adaptor

Quick Product Summary

The Roland WM-1D is a compact USB wireless MIDI adaptor designed to bring dependable, low-latency MIDI connectivity to computers and compatible Roland wireless MIDI setups without the clutter of traditional MIDI cables.

Ideal for Windows computers and Roland WM-series systems, the WM-1D offers a transmission range of up to 10 metres line-of-sight, while its high-performance Fast Mode reduces latency to just 3 ms for timing-critical playing and recording applications.

What Makes the Roland WM-1D Special?

The WM-1D makes it possible to integrate a computer into a wireless MIDI setup simply by connecting the adaptor to a USB-A port. Used with compatible Roland wireless MIDI devices, it can transmit note information, controller data, MIDI clock and other MIDI messages without requiring a conventional cable connection.

For demanding musical applications, Roland's proprietary Fast Mode provides extremely responsive 3 ms latencybetween compatible WM units. Standard Mode provides greater flexibility for multi-device configurations, making the WM-1D equally useful for streamlined home studios, live performance rigs and creative MIDI setups.

Who Is It For?

The Roland WM-1D is ideal for keyboard players, producers, electronic musicians, home studios and live performers looking to reduce MIDI cable clutter or add wireless MIDI capabilities to a computer-based setup.

It is particularly useful for Windows users who want to communicate wirelessly with compatible Roland WM-series equipment, as well as musicians building flexible MIDI systems involving computers, keyboards, drum machines and controllers.
