10 YEAR EXTENDED WARRANTY SCHEME

The product price includes 3 years' warranty and 30 day money back guarantee.

However, the Gear4music extended warranty scheme provides an enhanced service, and is designed to offer a higher level of protection than many 'free' warranties offered by some retailers and manufacturers.

The highlights of this enhanced warranty service are:

  • Warranty is extended to 10 years from the date of delivery.
  • Our Money Back guarantee is extended from 30 days to 180 days (terms apply after 30 days)
  • Collection and delivery costs are included for the first 2 years in the event of an item becoming faulty
  • Claim 50% cash back on the cost of the policy after 10 years if it has not been used!
  • Warranty is transferable if the item is re-sold
  • Loan or replacement equipment will be provided if the product isn't repaired within 30 days
  • If an item can not be repaired, a similar alternative product or cash discount (as defined in this policy) will be offered
  • The policy can be cancelled within 30 days, and at any time after that for a pro-rata discount

Please note that this extended warranty is currently only available on products sold within the UK, EU or EEA, and is subject to the terms and conditions as detailed on the extended warranty certificate provided.

For customers in outlying areas of the country, the price of the Extended Warranty may be marginally higher, due to the potential for higher collection and redelivery transport costs.

This enhanced warranty is in addition to the standard Gear4music and manufacturer warranty policies, and the Gear4music terms and conditions of trade. No statement or condition of sale contained within these terms affects or restricts your statutory rights as defined under the Consumer Contracts Regulation 2014.

CME WIDI for K.O. II & Medieval Bluetooth MIDI Interface Overview

The CME WIDI for K.O. II and Medieval is designed as a dedicated Bluetooth MIDI solution for teenage engineering's EP-133 and EP-1320. Acting as a virtual MIDI cable, it connects your devices wirelessly with no need for computers or additional cabling. With a latency as low as 3ms, it delivers a responsive playing experience that feels just like a traditional cable connection.


Adaptive Frequency Hopping ensures stable performance even in busy wireless environments, while smart connectivity algorithms optimise communication for every setup. Power is supplied directly from the TRS MIDI output of your K.O. II or Medieval, so the device runs fully standalone without extra power supplies.


It pairs automatically for instant use and can connect with a wide range of other Bluetooth MIDI devices including Yamaha, Roland, Korg, Akai and Roli. For those who want to expand further, the WIDI app allows grouping of up to five devices and personalised optimisation settings.


Pleas Note: Images are for reference only, the WIDI interface DOES NOT include any synth, sampler or groovebox.

Wireless MIDI made simple

The WIDI for K.O. II and Medieval removes the need for cables or computers when connecting your teenage engineering instruments. By acting as a virtual MIDI cable, it allows your EP-133 or EP-1320 to send and receive MIDI information wirelessly over Bluetooth. This means you can integrate your K.O. II or Medieval into a wider setup without worrying about tangled leads or limited physical connections.

Whether you want to control another piece of MIDI hardware, link with a controller, or sync with software on a computer or tablet, the WIDI handles the connection seamlessly. Once plugged into the TRS MIDI port, it is immediately powered by the instrument itself, keeping everything fully portable and cable free. Simply plug, pair and play.

Ultra low latency and stable performance

One of the main challenges of wireless MIDI is latency, but the WIDI addresses this with its unique smart connectivity algorithms. These algorithms manage data traffic and interference to deliver a latency of only 3ms between two WIDI units. This is faster than human perception and ensures that the playing feel is natural and in sync.

For comparison, standard wired MIDI transmits at 31.25 kbps, while WIDI operates at speeds of up to 400 kbps. This performance allows you to enjoy the freedom of wireless MIDI without compromising timing or accuracy. Adaptive Frequency Hopping further enhances stability by automatically avoiding crowded channels. This means you can use the WIDI in live environments or shared studio spaces without losing connection quality.

Compatible with a wide range of devices

Although designed specifically for teenage engineering’s K.O. II and Medieval units, the WIDI is not limited to those instruments. It connects with any Bluetooth MIDI device, including products from Yamaha, Roland, Korg, Akai and Roli. It can also pair directly with macOS, iOS, Android and Windows devices that support Bluetooth MIDI. With the addition of a WIDI Bud Pro or WIDI Uhost, you can expand this compatibility to platforms such as ChromeOS and Linux for optimal results.

Expandable with groups and app control

The WIDI app for iOS and Android unlocks even more possibilities. It allows you to form groups of up to five WIDI devices, with one acting as the central unit and four as peripherals. These groups can be set to communicate across all 16 MIDI channels, enabling wireless thru, split or merge configurations. Once saved, the groups automatically reconnect from memory, so you do not need to repeat the setup every time. The app also offers personalisation of settings such as latency or jitter optimisation, keeping your system tuned to your performance needs.

Fully standalone and easy to use

Power is drawn directly from the TRS MIDI output of your K.O. II or Medieval, meaning there is no requirement for an external power source. Setup is instant with automatic pairing, so you can go from plugging in to playing in seconds. The working range extends up to 20 metres in open space, giving you freedom of movement in rehearsals, performances and studio sessions. Despite this capability, the unit remains compact and purpose built to fit seamlessly with the teenage engineering design aesthetic.
