Bluetooth MIDI and beyond
On the 12th of December (2019) we launched the concept of WIDI Master. By doing so we set the goal to reach at least 1,000 registrants before we could move into the next phase of production. Now we’ve found that we’ve already reached that goal in the first week. We are thankful for your support for wireless MIDI over Bluetooth.
We now set a new goal and offer you an even better price. When we get 3,000 supports registered we will give an additional $10 discount coupon. In total we will give a $30 discount coupon to every registrants. Instead of $59 you will only pay $29. Beware, this price will only be valid when we reach 3,000 registrants for those registrant.
Along the way we’ve received several questions and a few concerns through our Facebook Group. Therefore we’ve taken the time to consider the next topics in this blog post. You can find them underneath.

MIDI over Bluetooth? What about latency?
When people hear Bluetooth, they think about latency and troubles with pairing. We ask ourselves is that true with Bluetooth MIDI? CME already delivered www.xkeyair.com and www.widibud.com to a wide range of professional musicians worldwide since 2015. Our wireless MIDI solutions are used by thousands of dedicated music makers. We have received much feedback over the years and never complaints about latency. Therefore we can honestly say that latency is not a problem with WIDI Master.
“Midi is a serial based protocol and not particularly fast anyway. Bluetooth quite happy handles a few megabits per second. Conversion time is negligible. It is very different from streaming audio!” Quote taken from Facebook
With WIDI Master we reduce latency even further by directly embedding the BLE MIDI protocol in the firmware of the device. You now can bypass your computer and play with wireless MIDI with limited latency. With that in mind, we are in an early stage of development. Therefore we are not able to share hard facts with you yet. Be sure to register at the end of this post. This way we can keep you updated along we develop further.
A little spoiler is that we expect to deliver a maximum round latency of 10-15 ms. Please read the next paragraph to understand what this means. MIDI over Bluetooth has been designed by Apple and is already used and acknowledged by top engineers of Yamaha, Korg, Roland and so on. It is the standard as approved by the international MIDI association.
Update – February 28, 2020 – Prototype latency test: 3ms minimum
Please keep in mind that every human hearing, every circuit, from audio interface to midi controller to monitor speaker, already has latency. When we mention 3ms minimum it is the latency minimum. It depends on the device you connect it with and which Bluetooth version you use. In this case it is tested with BLE 5. If you are looking for a test range, we can say latency is between 3-10ms. Again, depending on the device you connect it with.
When we say “a round latency of 10-15 ms.” for WIDI Master, we consider it a maximum when working with all other existing products. If you use 2 WIDI Masters directly, since we implemented both master and slave firmware, you will get much less latency than the reference (10-15ms). That is because you do not need to add extra latency from computer OS and iOS. In addition, you can also pair WIDI Master with any other BLE MIDI adapters or controllers directly.
We are aware that “latency” is a big word in the world of MIDI. We understand that. Most of the manufacturers will never share such numbers. We are sure, and have proven in the past, that with our wireless Bluetooth over MIDI solutions you do not need to worry about latency. Check out the video above to find out what real professional musicians like Jordan Rudess (Dream Theatre) and Jim Gilmour (Saga) show and tell about our Xkey Air. Both on stage and in the studio. The Xkey Air was released in 2015. The WIDI technology is only getting better!
Also we’d like to point out once more that we’ve embedded automatic pairing. This means WIDI Master automatically wil pair with any Bluetooth MIDI device. Therewith there is no more need for manual scanning and pairing of your Bluetooth MIDI devices.
What is the difference with Yamaha MD-BT01?
We have received this particular comparison question multiple times. We hereby take the time to briefly explain the difference. Yamaha only implemented Bluetooth Peripheral (slave). That is why you still need to connect your computer or iOS device to use this solution.
WIDI Master gives you all flexibility to connect any Bluetooth MIDI device or adapter (including Yamaha) directly. This is because it implements both Master and Slave mode in the same device.
This means that you now can connect all your MIDI hardware directly to each other. Without a computer. Without cables.
How do I connect two MIDI hardware devices wirelessly?
With WIDI Master you can easily connect two standalone MIDI hardware devices. You just use two (2) WIDI Masters. One for each device. Due to the automatic linking they will pair instantly. Now you can choose which will be your master and which will be your slave. With WIDI Master you have the complete freedom to work with your favorite MIDI hardware without wires.
An important note is that WIDI Master is fully standalone and completely wireless. Therefore It is important to keep in mind that the device is powered by the MIDI OUT port of your hardware. If you only have a MIDI IN or unpowered MIDI Ports do not worry. We are working on a solution to deliver the power you need.
Last but not least. We all are aware that Bluetooth has limitations when we compare Apple (i)OS and Windows/Android. For this we highly recommend to use our WIDI BUD. WIDI BUD will instantly pair with WIDI Master. Every device can join the wireless party.
