I have a iConnectivity iConnectMIDI2 4 port USB AND IOS midi interface with IOS Power Supply available for sale. It's new, simply available to test. I acquired 2 devices and this thing is so highly effective, I only need 1. Arguably one the very best (certainly many flexible) midi interfaces ever before. It has 2 usb ports for attaching 2 computers (Mac or COMPUTER) or one computer and an IOS tool (IOS cable television included), 2 midi din I/O and sends 4 ports to both computer systems. It has extraordinary port, network and cc transmitting so for instance, I have Lemur on my Ipad sending to my COMPUTER via 3 independent midi ports and I have the 2 hubbub midi I/O combined to the Fourth poert for equipment midi. Genuinely amazing and it functions faultlessly. I tried buying an universal power supply yet it really did not charge my Ipad so I purchased the iConnectivity one and it charges flawlessly.
I have the iConnectMIDI2 in initial box with all wires AND the optional power supply.
