I have a ridiculous number of MIDI devices and use three routers, a switch, a merger and a splitter. My name is Mark and I am a synth addict

The merger is a Kenton Merge4. Powered device which is semi-intelligent in that when it detects tempo messages on an input, it filters all tempo on the other three to avoid tempo doubling. It also has two outputs so can really help out in medium sized MIDI networks.
The splitter is a Phillip Rees V3. Simple 1in/3out that runs on a 12v battery. The battery lasts for years and years, but unfortunately Phil's not making stuff any more. Really a shame as his utilities were great.
When it comes to the sort of utilities I've mentioned above, I really recommend getting something powered. It might eat a powerpoint in your room if it's a mains-powered, but it saves headaches created by some devices not providing enough power over MIDI to run the unpowered MIDI utility. MIDI Solutions have a list on their website for referencing what devices will power their produces, so if you are considering any of their boxes, check that list first.
Now the "Doctor! Doctor! I think I have a synth habit" equipment:
The switch is a custom made box that I bought from a fellow who had the privilege of being paid to gut a government broadcasting company premises when they moved. It's probably does more than switch but I has a numpad and no instructions. I had to trial-and-error it to workout how to assign the switching rules!
The routers are an Akai ME80P, JLCooper MSB+ (both are now out of production and I really had to bide my time to get the MSB+) and an iConnectivity MIO4.
The MIO4 is a beauty and I can't recommend iConnectivity's products enough. The MIO4 is a 4in/4out programmable router with a USB MIDI host port on it also. The host port can run upto 8 USB MIDI connections using a decent powered USB hub. They have a 10port version of the MIO also, and although I was thinking of getting one and selling the MIO4, which would give me 6i/o more than currently, a better option would be to get a second MIO4 and while only gaining 4i/o's I'd double my USB MIDI hosting capability. The have a great support/community forum and you can get a list of working USB hubs on there. Their staff are really into what they make and listen to the community regarding how to make their products better. I have to stop talking about them or the page will be full of me gushing over how good iConnectivity are.
