The WM-1 Wireless Midi Adaptor leads the wireless MIDI revolution 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-1D Wireless MIDI Dongle (sold separately). In addition to MIDI note data, you can send MIDI sync for tempo, effects, LFOs, loops, and more. And you can do this all without connecting a single cable.
