Found these on eBay. Low cost alternative to the Kenton Host.
Just got mine in the mail, and it passed all my tests, responding to all 16 MIDI channels, and all 128 CC#s.
Tested with MIDI Fighter Twister, Akai LPD8 wireless, and old LPD8.
Using it to send MIDI from a Class Compliant USB MIDI only controller (Twister) to my Octatrack MK1.
Very lightweight, and very low profile, as seen next to my already small old 1st Gen iConnectMIDI:
DIN MIDI Out only, no two way input/output. But that works for me.
Supply your own USB power and USB Micro cable to power it.
Mine is working fine off a powered USB 3.0 MTT hub, getting power only at 5v/900ma, using the hub just to keep things simple on my desk. Also tested OK with an ancient Nook USB 5V/850ma adapter.
So just about any 5v USB power adapter would do the job.
Kind of a neat product. He is fashioning them out of USB battery packs, reusing the power board. These are about $2.30 ea on Alibaba. I can really appreciate the hustle and imagination. He’s sold over 50 of them on eBay from looking at all the positive feedback.
