Our stylish and very powerful M8U eX is a modern USB 3.0 MIDI interface with a total of 16 MIDI ports in one single device.

Featuring the popular MIDI auto detection technology that was pioneered by ESI, each of these 16 ports can either be used as a MIDI input or as a MIDI output, replacing not only regular MIDI interfaces like our previous popular legacy multi port MIDI interfaces with 8 inputs and 8 outputs, but providing also other possible configurations: for instance, you can use up to 16 outputs at a time or up to 16 inputs, or any other combination, like 12 outputs and 4 inputs. Each automatic input / output configuration is displayed via colored LEDs on the front panel.

If the number of ports is not enough, you can hook up multiple M8U eX to the same computer - a feature that is made easy also via the integrated fast USB 3.0 hub that allows you to connect other USB equipment like software dongles or USB keyboards and others to your computer. This literally turns M8U eX into the central hub for the MIDI and USB devices in your studio or live performance setup.

The 100% fully class compliant device can even be bus powered (or if needed for other USB devices, it is powered via the included 5V DC power supply) and it works out of the box without the installation of additional drivers on Windows 7, Windows 8.1, Windows 10 and macOS systems (both 32-bit and 64-bit). Yet, there is more: it also works as a standalone Thru and Merge solution for your MIDI devices. Selected via a push button on the front panel, M8U eX provides various configurations allowing you to merge multiple MIDI signals and send them out to a single port or to send out signals through multiple ports that are coming in from just one - all based on your individual needs.

All this makes our M8U eX easily the most powerful USB MIDI interface existing on the market today.

Old fashion quality. Love it.
Size: 25mm, Color: Two-Tone/Gold-Tone/White/25mm
I’m so pleased with my Timex watch. I can actually see the numbers and the added feature of the lighted face is great.

Perfect for Training (Swimming) Purposes.... 5 Star for what it does as a training watch!
Color: Black/Yellow
This is already my 2nd TIMEX which I use for my swimming practices.. This one beats the older model (Timex 51931 Ironman Triathlon) with some interesting changes: 1) The larger digits on this model makes it easier to read the numbers (as some mentioned to do so when running) even when I am swimming, with a quick flick of the wrist at the turn, it's possible to see the minutes and the seconds.... The older model had smaller number, thus not making it possible to do this. 2) The navigation on this model became quite easier. It was already easy on the older model but this one included instructions on screen, such as NEXT, DONE, + or - in order to advance with your practices and training... Plus a chance to change the way you want to see the information of the your laps (Laps in the big digits and splits at the smaller one, or the oposite) A Real nice add on by TIMEX. 3) A simple but effective wrist band "clip" (the tiny piece of strap that attachs the "extra" wrist band that is left after you put the clock on) It has a piece of rubber on the inside that locks on at the wrist band and does not make it loose or even letting it go as some other watches do sometimes. This is more effective underwater I think, as it remains the way you set your wrist, as the older model I had did not quite held in place all the time. 4) Plenty of memory (100 laps is really a nice number), maybe more then most will need but, as a swimmer I use to count splits over 100m (or yards) with many laps during one training... It is quite usefull. I go easily on 10 to 15 laps of the memory in one training. And with the date feature, that reminds when you did these times, it is quite usefull to keep track on the training with a spreadsheet, for instance... (as I do !) 5) A really big START/SPLIT buttom that is great to press when I am swimming laps and have to press myself at each turn at the pool. Just perfect. Never a miss ! And the feature which was already at most of the models, of the repeat countdown, and the start of a chrono, or a repeat (what I use the most) in order race agains your average rhitym inside a certain time frame that you can set it up ! And of course the flix technology, which is very good to have it... Just flick your wrist (when you set it to ON) and it will show you at night all info that you need. It is another great watch from TIMEX and it deserves a look, specially for the price. It is worth to pay a bit more if you are like me and uses a lot of the memory for the laps on swimming pool. Maybe for runners it can be quite a lot of memory, but the price difference is worth the change, for some of the options mentioned at this review. This is a really good watch to have.. Will you definatelly like as we all are at these reviews. :-) It deserves the 5 stars rating !

Great sports watch.
Color: Black/Yellow
I have to admit to being a bit of a watch fiend, having one for almost everything I do, but this is one of the most useful, yet cheaper priced items I've come to enjoy. When I work out I like as much information as I can get, so for running and biking I have a watch for that, but for swimming I needed a watch to help me count my laps and log my times. The Timex Ironman 100-lap watch does this quite well. I first got a Timex 50-Lap watch that I was able to find locally, but 50 laps is very limiting so when I found this watch for less money and a bigger face that had the lap/split time and lap number on the screen at all times I knew I had a great product. When you're finished with your laps just save your workout. The watch will then calculate some information like average lap time and best lap. I haven't completely messed with their data, but I think they average your times by throwing out the lap times that are the outliers, which is good for the accidental laps where you hit the wrong button, but it's not as great when you did a few sprint laps and they don't show up as your best time. If your best time isn't on there you can still recall it by going through each lap individually, but I think my sprint laps sometimes aren't listed as my best laps. I haven't messed with this feature much because it isn't important to me, and removing the outliers is good for looking at your actual pace. I have been able to push myself a bit more in the pool by having actual numbers to compare, which is very helpful. The other features on this watch I haven't used much, but for someone who can't afford a GPS watch and can use maps or a track this watch would be great for running or anything with laps or intervals. It has up to 9 interval timers and once finished it can either stop or repeat the sequence. It can do what's called chrono at the end, where it just switches to the chronograph feature after your timer or interval timers are finished. Overall this is a great watch and for most people who enjoy doing anything with laps look no further.
