Review: Loved it - Works perfectly and easy to use.
Review: These Widi links are a marvel, allowing me to connect a stone-age but wonderful Yamaha keyboard to the latest and greatest computer equipment. I did however have an issue installing them - my iPad would not recognise them. There was excellent and immediate support from the manufacturer and from the Facebook user group so I was able to identify the problem quickly - good support is rare these days so I think the manufacturer should be praised for doing good support. The issue turned out to be a) firmware needed to be updated and b) all other bluetooth profiles must be deleted before installation ( in my case it was an Apple Pencil causing the problem). So you must delete all existing bluetooth connections, then install and run a firmware update on the WIDI, and then re-install the other bluetooth profiles on top. Everything now works and is of high quality. Recommended.

## Questions & Answers

**Q: Will this work the same as a Yamaha md-bt01?**
A: 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.

**Q: Will this with qrs pianomation systems?**
A: 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.

**Q: More than 2**
A: 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.

**Q: Do I need two of these to connect two devices**
A: 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.

Hem hızlı bağlantı kurdum hem de gecikme yok denecek kadar az. Ipad pro 11 2021 sadece tek usb c portu var. Hub almaktansa kulaklık adaptörü aldım. Midi klavyemi de midi master ile bluetooth ile ipad e bağladım. Hiç zorlanmadım hemen çalıştı. Cubasis uygulaması hemen algıladı. Yani ihtiyacımı kablosuz giderdim.
