Will this work the same as a Yamaha md-bt01?

Yes, but much better. I own both. I've found the WIDI Master to have a better range and stronger signal than the Yamaha unit. It can also do something the BT01 can't. You can connect two WIDI Masters together without the need for a computer or mobile device. Just plug and go. It's a fantastic product.

Will this with qrs pianomation systems?

I hooked it up to a Pianomation system, but it is a little tight fit. Works good though. You have to hook up the midi out as WIDI Master gets its power from MIDI out.

Yes. With WIDI Group Connection and Group Auto-learn features, you can do 1-to-4 MIDI Thru/Split and 4-to-1 MIDI merge wirelessly. Please check cme-pro support page to get all instructions.

Do I need two of these to connect two devices

Maybe. I use one of mine to connect to MainStage on my Mac and with this scenario, I only need one since the computer has Bluetooth.. Connecting two keyboards together requires two, one WIDI Master for each keyboard.
