Kenton MIDI USB Host
USB Host to MIDI converter for 'Class Compliant' USB MIDI Devices
Your USB device is plugged into the USB MIDI Host instead of into a computer. It provides MIDI In & Out sockets for USB MIDI keyboards and controllers which have only a USB B type socket.
For example, used with a USB-Solo, it allows the USB-Solo to be used in a standard MIDI setup, just like a Pro-Solo.
It has a USB Host port (USB A type socket), a MIDI In and a MIDI Out (both 5 pin DIN).
MIDI data received at the MIDI In socket will be sent to the USB device. MIDI data received from the USB device will be sent to the MIDI Out socket.
The attached USB MIDI device MUST be 'Class Compliant'.
The MIDI USB HOST is powered by a regulated 5V mains adaptor (supplied), and can supply up to
500mA of buss power to the attached USB device. This product is supplied with a multi-region power supply suitable for use in most countries.

You can connect one "Class Compliant" USB device to the MIDI USB Host. The device must be
connected directly to the MIDI USB Host, it cannot be connected through a USB Hub.
It is recommended that you attach your USB device to the MIDI USB Host before applying power. Then
plug-in and power the power adaptor. The active LED should be lit up. If you apply power with nothing
plugged into the MIDI USB Host, the Active LED will flash steadily; this is to indicate that it is waiting for
a suitable device to be attached. If it is still flashing when you have attached your device, then it is
possible that your device is not class compliant, however you could try turning off the power and start
Some USB MIDI devices have two modes of operation and can be set to operate in Class Compliant
mode even if this is not the default. The Class Compliant mode might be called “generic driver”, the
other mode may be called something like “advanced driver”. Consult the device manual to see if the
mode can be set for Class Compliant.
If you unplug then re-plug the USB cable while it is powered the device might reconnect, but it is not
It is essential to use only the supplied 5V regulated power adaptor. Applying a voltage higher than 5V
to the MIDI USB Host will probably not damage the MIDI USB Host itself, but it could damage any
attached USB device as the 5V is passed on to the attached USB device for buss power. There is
protection circuitry inside the MIDI USB Host to protect against reverse polarity and over-voltage, but
these should be treated as a last resort and are not guaranteed to prevent damage to an attached USB
device in the event of over-voltage as the USB buss voltage could rise to 6.5V before being clamped.
Care should be taken to ensure that power adaptors for other pieces of equipment are not accidentally
plugged into the MIDI USB Host.
If the input voltage rises above 6.5 volts then power will be shut off. The LED will go out and the unit
will not operate again until power has been removed for at least 60 seconds. This allows time for the
thermal fuse to reset.
Look for a ‘generic driver’ setting, your device must be class compliant. Some devices (notably Roland devices) have a setting for an ‘advanced’ driver, if your device has this setting turn it off. Most EDIROL products have this setting on by default and can be made to work by changing it – refer to the manual.
Check for firmware updates. Some Novation controllers/keyboards can have their firmware (software) updated and will work with the new version. This may only apply to the the Remote Audio, LE or SL series, and not the 25/37 models.
We have seen a recent tendency for a few keyboards to incorporate a USB hub. Unfortunately keyboards with built-in USB hubs will NOT work with the MIDI USB Host. You can recognise a device with a built-in USB hub as it will have one or more USB "A" (rectangular) sockets as well as the "B" (square-ish) type normally found on a device. The "A" type sockets are the same as those found on your computer. Devices with only a "B" socket will normally be OK if they are "Class Compliant". The following keyboards are known to incorporate a USB hub and therefore will not work with the MIDI USB Host:
Korg Microkey 61
Korg Microkey 49
Korg Microkey 37
The following keyboards, although "Class Compliant" do not work with the MIDI USB Host:
M-Audio Keystation mini 32 (we haven't yet got to the bottom of why this one won't work)
To the best of our knowledge all other "Class Compliant" USB MIDI keyboards do work. We get a lot of enquiries about the Yamaha P-105 piano and the Teenage Engineering OP-1, both of these definitely work fine.
If you buy directly from Kenton and your keyboard doesn't work with the MIDI USB Host (see conditions below), then we will refund your money in full (including the original shipping cost). Conditions for above offer:
1) The MIDI USB Host must have been bought directly from us.
2) We must be notified within 7 days of delivery to you.
3) The device you are connecting must be "Class Compliant"
4) The device must not incorporate a USB hub
5) The MIDI USB Host must be returned to us within 30 days.
