WIDI: Which Device Will You Connect?


What is your use case?

There are thousands of products that use MIDI on the market. Both new and second-hand. It is a challenge for all of us to answer all questions about every MIDI device on today’s market. This blog will explain which WIDI product you can use for your specific case!

Due to the fact that there are many other forms of MIDI connections on the market, we started the development three WIDI products to cover the wide variety of MIDI devices and ports: WIDI Master, WIDI Jack and WIDI Uhost!

WIDI in short

In its essence WIDI Master and WIDI Jack are the same products. Same goes for WIDI Uhost and WIDI Bud Pro. The main difference is that WIDI Uhost and WIDI Jack offer external power options and changeable cable options to widen the number of use cases.

WIDI Master - DIN MIDI >> Learn more
WIDI Jack - DIN MIDI + TRS MIDI + external power + changeable cables >> Learn more

WIDI Bud Pro - USB MIDI >> Learn more
WIDI Uhost - USB MIDI + external power + changeable cables >> Learn more

Please note that WIDI Jack comes in preselected bundles for your convenience. WIDI Uhost does not contain any cables in the package. The reason for this is that there are too much usb types and not one common solution. Adding cables would mean adding multiple cables to cover a variety of use cases.

This would mean many people would pay for cables they already own, do not need or can purchase affordable locally. Therefore, the it was chosen to add cable packs as an option covering the most common use cases.

If you experience challenges selecting the right WIDI product, please take your time and read this blog. It starts with a simplified buyer's guide that will help you to select the right WIDI solution for your MIDI device. If this does not answer your question, feel welcome to read the remaining part of this blog and reach out to our support.

Discover the WIDI family

WIDI family of products

WIDI Master

Our first WIDI family member is WIDI Master. It is your 5-PIN MIDI DIN Bluetooth MIDI adapter. WIDI Master will need power from the MIDI device you connect it with. The standard MIDI OUT or THRU port delivers 3.3v or 5v through the 5-pin DIN MIDI socket. It is a standard as as suggested by the international MIDI Manufacturers Association.

On our support page, you can find an open source compatibility list. On this list, people from the Community of MIDI Enthusiasts, add devices that they have tested and confirmed to work with WIDI Master.

WIDI Master + iPad

WIDI Master + Korg

WIDI Master + Linnstrument

WIDI Master + MIDI Guitar

WIDI Master + WX5

WIDI Master + Elektron


WIDI Master + Nord

WIDI Master + Behringer

WIDI Master + Novation

WIDI Master + Yamaha

How does it work?

You will need 2x WIDI device to pair two MIDI devices. As you need to add Bluetooth MIDI to both devices. This will allow you to connect instrument to instrument without the need of a host such as your computer or mobile device. 

You will only need 1x WIDI device to pair with Bluetooth MIDI devices such as mobile devices, computers and Bluetooth MIDI controllers.

For instance, you will only need 1x WIDI Master to pair your device with iOS or MacOS. The advantage of Apple operating systems is that it integrated Bluetooth MIDI as a standard.

Please always visit our support page to check out the setup videos available. You will also learn here how to upgrade to the latest firmware and how to utilise MIDIMTTR as a great tool for iOS and Bluetooth MIDI.

For Windows PC, it is different. As it depends on your operating system. If you have Win10 v1909 or higher, you can work with Bluetooth MIDI.

Unfortunately, on Windows, Bluetooth MIDI is not integrated as a standard in every music software application. The question if Bluetooth MIDI works for your setup, completely depends on the software you use. You need to be able to set Bluetooth MIDI in that software. Please make sure to check out our support page and the MIDIBerry-IO for WIDI solution.

Recently the Korg BLE MIDI drivers have been made available to use with your Windows solution as well. That said, for optimal performance consider WIDI Uhost and WIDI Bud Pro as the hardware solution.

Basically, if your product has a 5-PIN DIN MIDI OUT that follows the standard as set by the MIDI Association, your MIDI OUT will deliver power to WIDI Master and it will work. You can simply check your device and see what kind of MIDI port it has.

WIDI Master

Check your manual and ensure your MIDI OUT delivers 3.3v or 5v


WIDI Jack offers an external power supply option. Remember? Some devices do not deliver power on MIDI OUT and do not follow the MMA standard. Others only have MIDI IN. That is why we came up with WIDI Jack, to allow you to add WIDI to any device with 5-PIN DIN MIDI ports.

Basically WIDI Jack is the same device as WIDI Master. Only it offers all connectivity solutions that WIDI Master did not.

  • MIDI devices with TRS (mini jack) MIDI (2.5mm-3.5mm (1/8") / Type A+B)
  • MIDI devices with only MIDI IN like Korg Volca Series
  • MIDI devices with DIN-6 mini MIDI like Yamaha Reface Series
  • MIDI devices with unpowered 5-PIN DIN MIDI
  • MIDI devices with powered 5-PIN DIN MIDI (= WIDI Master)

Add Bluetooth MIDI to more MIDI devices

WIDI Jack is designed to ensure the functionality of WIDI Master plus additional use cases. The main difference is that it allows an external power source and the ability to change the connection cable. This way you can use WIDI Jack with almost any MIDI device.

Recently, upon request, the WIDI Jack + TRS 6.35mm (1/4") has been added. Today there are 5 different cable options available in a bundle with WIDI Jack or as separate accessory cable add-ons. Just visit the dedicated WIDI Jack page to see the different options available.


WIDI Jack will work with any 5-PIN DIN MIDI port through external power supply option via USB-C port

WIDI Jack works with TRS 2.5mm (3/32"), 3.5mm (1/8") and TRS 6.35mm (1/4"). Plus it can switch between Type A and Type B TRS.

WIDI Jack Yamaha Reface

Yamaha Reface Series with single 6-PIN MIDI DIN terminal works with WIDI Jack as well.

WIDI Uhost Use Cases

WIDI Uhost is designed to be the wireless MIDI USB host for your class compliant USB MIDI device. Besides this, it is a MIDI USB dongle for any PC, tablet or smartphone. As Bluetooth MIDI is not always integrated in your operating system, with WIDI Uhost you can simply add Bluetooth MIDI to your setup.

Basically WIDI Uhost offers all wireless MIDI solutions for class compliant USB MIDI devices.

  • Solution 1: Connect MIDI devices that operate only as USB client
    Plug WIDI Uhost in your class compliant USB MIDI device and transmit MIDI over Bluetooth between your MIDI hardware and BLE MIDI devices.
  • Solution 2: Connect MIDI devices that operate as USB host
    Plug WIDI Uhost in the USB host of your MIDI instrument and add advanced Bluetooth MIDI to your MIDI hardware.
  • Solution 3: Connect computer and smart device without Bluetooth MIDI
    Plug WIDI Uhost in the USB port of your computer and ensure ultra low latency Bluetooth MIDI without having to upgrade your PC, tablet or smartphone and even bypass the Bluetooth MIDI limitations of iOS/MacOs.

WIDI Uhost Cable Packs

As there are many different USB ports, it is impossible to satisfy and offer all different cables. This would simply not be cost-efficient. Therefore it was chosen to offer you the most common solutions in two different cable packs.

For connecting any USB MIDI device with WIDI Uhost get one of the cable packs or buy your own cable to USB-c (Uhost) locally!

You can always get yourself affordable local USB cables that have one USB-c connector to attach to your WIDI Uhost. From our shop you can order the following two packs

  • WIDI Accessory USB-B OTG WIDI cable pack
    This is an accessory for WIDI Uhost containing 2 cables that are most commonly used for standard MIDI controllers:
    1x USB B 2.0 OTG to USB-C cable
    1x USB A 2.0 to USB-C cable
  • WIDI Accessory USB micro-B OTG WIDI cable pack
    This is an accessory for WIDI Uhost containing 2 cables that are most commonly used for slim sized and portable MIDI controllers:
    1x USB micro-B 2.0 OTG to USB-C cable
    1x USB A 2.0 to USB-C cable

Bypass the limitations of your computers and mobile devices with WIDI Uhost

Operating systems (MacOS, ChromeOS, Windows, Linux, iOS, Android) and the way music software applications (DAW, apps, plugins) are build can influence your latency performance heavily.

Because the dedicated WIDI firmware is directly embedded in all WIDI products, you can bypass (the limitations of) your computer's operating system (OS). And benefit from fast and reliable wireless MIDI connectivity.

With WIDI Uhost you can benefit from automatic pairing and ultra low (3ms) latency performance via Bluetooth. That is we call WIDI Uhost the Turbo BLE Dongle. It simply boosts BLE MIDI performance of any operating system. 

As you might know the alternative to this specific use case of WIDI Uhost is the WIDI Bud Pro. WIDI Bud Pro is the successor of the legacy WIDI Bud (2016) and is fully dedicated to perform as a USB A Bluetooth MIDI dongle that offers all solutions of today's WIDI technology.

Furthermore, it allows you to add Bluetooth MIDI to any class compliant USB MIDI device. With its secondary USB-C port, you can also utilise an external power source and work with MIDI instruments that only offer MIDI over USB and are powered by this USB port.

WIDI Uhost Power Supply

WIDI Uhost offers some amazing solutions when it comes to power sourcing. That is the magic of making an all-in-one solution. Basically, WIDI Uhost offers three ways of operation when it comes to power supply:

  • WIDI Uhost can be powered all kinds of standard USB power sources: USB bus power, USB power supply, USB power bank, etc.
  • If your MIDI device has a USB host connector (USB-A slot), it can also power WIDI Uhost. 
  • MIDI device which only have a USB client connector (peripheral, USB-B or micro-B slot), will require power from Uhost via its USB-c port.
  • The external power option will power WIDI Uhost. Plus WIDI Uhost can pass 500mA to power your (bus powered) MIDI device which is connected to WIDI Uhost.

In other words, with the right cable(s) and these smart development solutions, WIDI Uhost is the 3-in-1 wireless solution for all USB MIDI devices. Including computers, mobile devices, USB MIDI controllers and USB MIDI hardware.

Adding WIDI Uhost to the equation will allow high performance Bluetooth MIDI. With and without computers. Besides this, you can enjoy the upcoming developments of advanced wireless MIDI that already have started with group connectivity. Therewith WIDI as a BLE MIDI technology is your premium Bluetooth MIDI solution.

WIDI Uhost compatibility 

When using WIDI Uhost as a USB host, it supports most plug-and-play ”class compliant" standard USB MIDI client devices. It is important to understand that USB client devices that need special drivers are not compatible with WIDI Uhost. If your USB MIDI device falls into the following conditions, it is not compatible with WIDI Uhost:

  • USB devices that require the installation of special drivers are not supported.
  • USB devices that include USB hub function are only supported in the USB client device role (not as a host)
  • USB devices with multiple (virtual) MIDI ports will only function on the 1st USB MIDI port.
  • "Combined Device Class" USB port (Audio + MIDI via 1 single USB port) needs WIDI USB firmware v1.6 or higher!
  • To allow WIID Uhost to function as a USB host, you will need USB OTG cables between your MIDI controller and the WIDI Uhost.

Generally speaking WIDI Uhost is specifically developed to add Bluetooth MIDI to standard USB MIDI devices. It works as a one-on-one solution, adding Bluetooth MIDI to that specific USB MIDI device. Therewith it can add 16 MIDI channels to one USB MIDI device.

WIDI Bud Pro

Back in 2016 the WIDI Bud was released. It was the first central Bluetooth MIDI dongle available on the market. As WIDI Uhost offers all wireless solutions for any USB MIDI device, the new WIDI Bud Pro is mainly developed to act as a Bluetooth MIDI super dongle for computers and smart devices (USB hosts).

It is the most simple, yet effective solution to add wireless MIDI via Bluetooth to any operating system. It works like a charm. Simply put it in your standard USB-A terminal on your laptop, computer or other operating system and you add Bluetooth MIDI to your setup.

You can plug, pair & play instantly and without any hassle. The best thing is it is compatible with all standard BLE MIDI devices and WIDI devices and will work with any operating system including macOS, iOS, Windows, ChromeOS, Linux and Android.

If your MIDI device has USB Host connector (USB-A slot), like your Korg Kronos, it can also work with WIDI Bud Pro to add that BLE MIDI layer to your USB host.

WIDI Bud Pro vs WIDI Uhost

All those different types of MIDI terminals and associated protocols can be really overwhelming for you. That is why Bluetooth MIDI is in essence the solution for this. That is because when adding Bluetooth MIDI to any MIDI device, you no longer have to think about terminals and connection types.

That said, you still have to consider which WIDI device suits your setup. To simplify this, you can consider that WIDI Master and WIDI Jack are basically the same products. The only difference is the switchable cables and the external power for WIDI Jack. 

The same goes for WIDI Uhost and WIDI Bud Pro. The optional power via USB-c and the switchable cables on the WIDI Uhost make it the premium solution for every USB MIDI use case. This includes bus-powered USB MIDI controllers.

To make the decision making process more easy for you, please note the comparison between both devices underneath. The comparison is limited to emphasize the difference. If you are interested in the entire specification please visit either the WIDI Bud Pro or the WIDI Uhost product pages.

Evolving Wireless MIDI technology!

WIDI is in essence a point-to-point solution. It is like a virtual MIDI cable allowing you to connect one device directly with one other. The new firmware (Dec, 2020) will allow up to 5 Bluetooth MIDI devices in a group. This is what we call the smart hub functionality. It makes 1-to-4 bi-directional connectivity via Bluetooth MIDI possible.

You can simply set these groups - and recall those settings at any moment - with the user-friendly app. Furthermore, it you will be able to set names to your WIDI devices and easily manage your wireless MIDI setup in a virtual environment. Interested in WIDI groups and the Group Auto-Learn feature? Learn more!

Also, the latest app update (December, 2020) will allow you to personalise your settings and optimise performance for lowest latency (keys, chords, MPE), jitter (real time, sequencing) and ultra low power mode (battery powered devices like MIDI wind instruments).

Connectivity: Automatic Pairing - MIDI Thru - MIDI Merge - Groups

With the latest firmware (v0098 and up) you can create groups of max. 5 WIDI devices. In essence this means you can now replace your MIDI Thru and Merge boxes. Thus maybe even your MIDI interface. By bypassing those middle men, you can optimise performance of your MIDI setups ánd go completely wireless.

When pairing 2 WIDI devices, this is done fully automatically. You do not need to worry about a thing. The WIDI devices pair and automatically switch between the central and peripheral role. This is Bluetooth wording for the things we used to know in the world of MIDI as master and slave. Also, they transmit MIDI messages bi-directionally. You simply power up your WIDI devices, and the rest is fully automated.

When connecting with another BLE MIDI device. Like you computer or iOS device. The architecture of those devices force manual pairing upon you. This is a limitation that is part of their infrastructure. To bypass those limitations and benefit from low latency, automatic pairing and group connectivity, you solution will be WIDI Uhost.

When you go into more complex setups with wireless group connectivity, you need to educate yourself to fully benefit from these features. For instance, your group always has 1 central. Besides this you can add up to 4 peripherals. This means you need to manually force the role of your WIDI devices first. Next you create the group in the user-friendly app and save that. When you reboot your devices, all settings are loaded by default.

As communication is duplex, you actually create a MIDI Thru or MIDI Merge functionality. With duplex we mean that communication is bi-directional. You can talk in two ways between your devices. This is equal to adding two cables between 2 MIDI devices.

In short. this means that with this firmware (v0098 and up), you can bypass MIDI interfaces, MIDI merge boxes and MIDI Thru boxes. You now can create the following wirelessly:

  • 1-to-4 MIDI Thru - Group of max. 5 WIDI devices
  • 4-to-1 MIDI Merge - Group of max. 5 WIDI devices

And yes, you can run multiple groups at the same time. Imagine where this can take you. Advanced virtual cable management via a user-friendly app....

As per January 2022 you can add other standard Bluetooth MIDI devices to WIDI groups via WIDI App. Learn more!

WIDI: Wireless MIDI for all MIDI devices

WIDI distinguishes itself from any other Bluetooth MIDI technology available through its unique SCA technology. SCA is a collection of highly effective algorithms that optimise the performance of WIDI in any given situation. 

We have tested and selected the most advanced Bluetooth module with optimized antenna design to deliver reliable connectivity. Therewith WIDI delivers ultra low latency and stable connectivity over Bluetooth.

WIDI offers Bluetooth MIDI adapters and interfaces for any MIDI setup, device and instrument.

WIDI: Connect MIDI instrument to instrument without computers or mobile devices

WIDI: Connect MIDI instruments with computers and mobile devices

As mentioned we are looking forward to an entire family of WIDI members. Besides the current WIDI Master and Jack, we will launch WIDI Uhost early 2021. After this, we will move forward, together with you, to expand with WIDI HUB4 and PED3.

Our mission is to deliver Bluetooth MIDI to all MIDI enthusiasts. Creating a solution that is open to any other manufacturer. No matter if it is Apple, Microsoft, Linux, Google, Roland, Yamaha, Korg, Roli and many of those neat dedicated developers like Genki Instruments, Jammy Guitars, Airturn and Pirate MIDI.

Also, we are talking with app developers like OnSong, Kronos Remote, Audiobus, Fluid Pitch and Strymon Iridium Controller to allow even better integration with top notch music apps. If you want to read more about a specific use case, go to this blog.

As we receive many requests from our active community for dedicated solutions, there are many concepts we will share in our Facebook Group first. Be sure to join this group if you want to contribute and be part of the development of WIDI.

WIDI Uhost: Start Guide
  • Wow, that would be a dream come true if Widi UHost also contains a battery to provide USB power to the device! Will it work with USB powered devices?

    • It does not work with a battery. It works with a double USB-port to add an external power supply. You can then use a simple 5v USB power bank to ensure all is powered.

  • Why not add a 2,5/3,5 mm in and out MIDI (like the Jack) to the Uhost. That would be really powerfull and flexible! I would order at least two or three!

    • Because USB MIDI is totally different to TRS/DIN MIDI! 😉 So, it will not work this way. What can be done is adding both features to an advanced WIDI product. Then again, this will mean different pricing.

  • I am so amazed at how well this product works. Just took it out the box hooked it up and it works perfectly. From 75 ft away with some obstruction between didn’t missed a note and very low latency. Great product

  • I have ipad with ONSONG which is connected via bluetooth to widi jack 1 which is wired connected to quad cortex and listen to channel 1. The widi jack 1 is wireless connected to widi jack 2 which is wired connected to zoom rfx2200 and listen to midi channel 2.
    My problem is:
    If I send with ONSONG a midi command to change pc on rfx2200 it doesn’t work. It looks like midi through is not working. Any ideas how to solve this?
    Thanks for helping me.

  • Does the Widi master work with the Alesis vortex and Roland integers? If so how will it connect with just midi out on the vortex?

  • Can you tell me how I can connect the WIDI Uhost to a device with a USB C port? I have a Novation Launchpad X and it’s got a USB port. Will the Uhost come with a USB C to USB C OTG cable? Thank you

    • Thanks for reaching out on this matter. The short answer is: no, it will not.

      As there are so many different USB terminals and cables, it is impossible to offer all solution. To keep it cost-efficient, the WIDI Uhost does not come with any cables.

      What you can do is either get your desired cable solution locally and affordable or go for the two mentioned cable packs. In your specific case, for usb-c to usb-c otg, the solution is to get one locally or via Amazon.

      Hope this helps.

      • Ok great thank you. As long as there is an option available then I’m happy!

        One more question, if I want to pick up an additional WIDI Master, can I also do this at a discounted price? I already purchased two of these from your initial crow-funding for this product & have subsequently purchased your WIDI Jack through an online retailer.

        Thank you

        • Unfortunately that is not possible. The discount is only for products in pre-sale. In this case it are WIDI Uhost and WIDI Bud Pro.

          Hope this helps.

  • Let’s say there is an UHOST connected to the computer and there are 4 WIDI Masters connected to 4 midi devices. Can I play those 4 midi devices with 4 virtual instrument running on the computer?

    • Yes. You can use 1x 16 MIDI channels per WIDI group and create a group with 1 central (Uhost) and 4 peripherals (WIDI Masters). Next you can route this 16 channels to the different instruments on your computer. At this stage limited to the 16 MIDI channels available via your Uhost. Hope this helps!

      • As I understood, Uhost will work as one physical MIDI port that can handle up to 16 midi channels, and out of them, four peripherals (WIDI Masters) acts like four individual midi channels.

        I have an old Roland A80 midi controller with 2 Physical MIDI IN Ports and 4 Physical MIDI OUT Ports. The problem here is, one WIDI Master has 2 Jacks for MIDI IN and OUT (If I’m understood precisely). So only one MIDI jack of the WIDI Master can plug into the keyboard MIDI out ports. If I connect one UHOST to the computer and 4 WIDI Masters with only one jack plug into keyboard MIDI outs, will the keyboard be able to play four virtual instruments on the computer?

        • I think that is what you can do.

          For WIDI Master, it can operate as standalone when the large main adapter is connected to a powered MIDI Out. This way you can attach for single MIDI OUT parts of WIDI Master.

          Next you can create a wireless MIDI group with the Uhost as the central and the 4x WIDI Master as your peripherals.

          After setting that group via the WIDI iOS app and saving it to the default memory of your WIDIs, on start up they will pair automatically as the group. To control 4 separate virtual instruments within your computer or via your DAW, you need to route the 16 MIDI channels properly between your controlling keyboard and receiving virtual instruments.

          As long as the Roland A80 provides power on all 4 MIDI Outputs, you will be good to go. If this is not the case, your option would be WIDI Jack + 5-PIN DIN cable option.

          Hope this helps!

  • Nice pricing for the USB-devices. Too bad that the DIN-prices went up again. It will cost me 100€ to connect an old keytar to an old keyboard. For just hobby a bit too much for me…

    • Great to hear that you like our development. As always with innovation, when the market is still small, manufacturing and production is relatively expensive. When sufficient people move to wireless MIDI solution, we can negotiate better pricing for bulk and parts.

      In our webshop we have two different prices. One during the crowd creation and introduction of a new product. The other one is the regular price. Next, it is up to the market of international resellers to decide their own pricing.

      Simply wait until there is a good offer from your local reseller. Like Amazon Prime Day on June 21/22. Or similar offers from Sweetwater, Thomann, Gear4Music or Bax Music.

      And if you can, always join the presale, It is absolutely the best price offer we provide.

      Hope this helps!


  • Very confused right now lol. I’d like to be able to wirelessly connect
    (1) Native Instruments Traktor Z2,
    (1) Native Instruments Machine MK3, and (1) Presonus Faderport 8 to my MacBook Pro wirelessly. Is this possible? They all 3 connect using USB midi. If so which product and accessories do I need? Thanks for any information you can provide!

    • Hi Benjamin, my apologies for my late reply. I missed your comment.

      For USB MIDI your solution is the future WIDI Uhost. It is currently in pre-order with discount. You can apply coupon BLEMIDI and we expect shipping half of October 2021.

      If you want to create a wireless MIDI group, this can only be done with WIDI devices. Your MacBook Pro cannot be used with its integrated Bluetooth MIDI. This is because in the architecture of Apple, the Bluetooth address changes every 15 minutes for security reasons.

      You can bypass this limitation of your laptop by adding WIDI Bud Pro. It is also on pre-sale, just like WIDI Uhost.

      With those 4 devices you can create a WIDI group. You can set that once via the WIDI App and store it as default in your WIDI devices. Next time you power them up, they will pair automatically.

      Hope this helps.


    • Ohw I forgot. About accessory cables. It depends on what kind of role and USB port your device offers. In our cable packs you have two cables. One for external power (if needed) and one for MIDI data via USB. The second one can also redirect power to your device when it is bus powered via USB. That is what we call an OTG USB cable. It can be for both data as well as power.

      I think all your MIDI devices act as a USB device and have the square USB port that is USB-B. So your best option is https://www.cme-pro.com/product/widi-accessory-usb-b-otg-widi-cable-pack1/

      Hope this helps too!
