Bernie, the Widi Master has standard 5-pin midi in an out whereas the Widi Bud is a USB Bluetooth MIDI receiver. As they have different connectors, they won't replace each other, but rather work together with each other and any other Bluetooth MIDI devices without the need for a computer or an IOS device.

Say that you want to connect your MIDI harmonica over Bluetooth to an old MIDI module only with 5 pin MIDI connectors. Your MIDI harmonica sends MIDI over Bluetooth by the Yamaha device we talked about, but how would the old module receive MIDI over Bluetooth? Yes, the WIDI Bud, but you need a USB MIDI host (or computer/IOS device) like the Kenton USB MIDI host you own. Not anymore. The WIDI Master will act as a Bluetooth receiver (and transmitter) directly connected to the 5 pin MIDI input on the midi module. This will be really handy.

Teds, it will be $59, but if you just sign up, you will get a $20 discount coupon. Once 1,000 people show interest in the product, they will go into production. By the way, I asked Panda Audio to see if they would consider making a USB MIDI transmitter. They said they would consider. For now, there is only company in the world that makes it. Starr Labs. The USB MIDI transmitter/receiver is pricey at $450. I just use a $50 Yamaha USB Bluetooth MIDI transmitter.
