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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by ツ***ヨ on April 4, 2026* EWI4000sとWindows11 PCを接続するために使用しました。PC側はPCのBluetoothではなくWIDI Uhostを使用しているため、特に設定は必要無く挿すだけで使用できました。 DAWを通しての演奏だけでなく、Vyzexによる音色エディットにも支障ありません。 ### ⭐⭐⭐⭐⭐ Review *by に***い on December 11, 2025* 2台購入し、お互いを接続しましたが、電源を入れるだけでつながりました 上手く繋がらない場合は、１度電源を入れ直すと良いです ### ⭐⭐⭐⭐⭐ Review *by 野***之 on April 25, 2025* MIDIケーブルの完全な代替ではありませんが、スマホ・タブレットからBLE-MIDI接続して、エフェクター・シンセの音色切換を行う程度なら問題なく使えます。 ## Frequently Bought Together - CME WIDI Master - Bluetooth (5) MIDI Adapter for 5-PIN DIN MIDI - No Battery, Powered via MIDI Out - Wireless MIDI for Synthesizer EWI Keytar Pedalboard Digital Piano - CME WIDI Jack - Bluetooth MIDI Interface for TRS/DIN MIDI devices - Power by MIDI Out or usb-c - Ultra low 3ms latency wireless MIDI for Synthesizer EWI Keytar Pedalboard Digital Piano --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/754109251-cme-widi-master-wireless-midi-ultra-low-latency-bluetooth-5](https://www.desertcart.jp/products/754109251-cme-widi-master-wireless-midi-ultra-low-latency-bluetooth-5) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-04*
