About WMI Connect

WMI Connect is the app for the Hughes & Kettner WMI-1, a bidirectional, wireless MIDI interface optimized for use with the fully programmable tube amp Hughes & Kettner GrandMeister 36 and the matching GrandMeister remote app for iPad. It works with any iPad with iOS 7 or later and offers so many more options to every GrandMeister user: imagine being able to watch and touch your tube tone from the front of the stage with an iPad on your microphone stand – and then being able to adjust reverb levels, gain or EQ settings without having to run to your amp five meters behind you. The WMI-1 can serve as an access point for stages and rehearsal rooms where Wi-Fi is not available, or as a client connected to a router in a network, such as a home network. It perfectly matches the needs of guitar players: no battery, latency-free, and the option to include a MIDI foot controller in the setup. The WMI-1 offers an additional MIDI input that merges the commands from the iPad and from a MIDI foot controller, and the GrandMeister’s MIDI port provides phantom power to the WMI-1. To use the WMI-1, all you need to do is select the WMI-1 as a Wi-Fi network in the Wi-Fi settings of your iPad, or connect it to your home network using the WPS function. Although the WMI-1 is optimized for use with the Hughes & Kettner GrandMeister, it also works with any Hughes & Kettner amp featuring a 7-pin MIDI input (phantom powered) and any app for iPad that supports CoreMIDI.
