V-MIDI is the only Core MIDI interface to enable musicians, producers and DJs to control Core MIDI compatible iOS apps with their USB MIDI hardware of choice and power both devices at the same time. Either that choice being drum pads, keyboards, synths, DJ controllers, or any other USB MIDI hardware, V-MIDI simply picks up the USB MIDI signal and converts it via 30pin connection to iOS devices. With the included power adaptor, V-MIDI charges iOS devices and powers USB MIDI hardware simultaneously, which is ideal for long studio sessions and on-stage performance.
