A Roland Solution Designed for Modern Setups
The WM-1 is part of Roland's WM series dedicated to wireless MIDI, designed to meet current needs: playing, programming, and synchronizing instruments without the hassle of cables. The goal is clear: maintain the responsiveness of a traditional MIDI stream while gaining freedom in the creative space.
Who Is It For and What Are Its Uses?
Ideal if you use a keyboard, a drum machine, or any device equipped with MIDI In/Out ports and want to communicate wirelessly with MIDI music apps on iOS and Mac. The WM-1 is also suitable for setups where the controller is far from the computer or when you want to move freely without constraints.
Standard/Fast Modes: Timing Priority
The Standard mode covers most situations and can support up to four devices. When rhythmic precision is critical, the Fast mode reduces latency to 3 ms (up to two devices), useful for real-time playing, tempo, and tight synchronization (effects, LFOs, loops, etc.).
