multiple hex connected in series. Any limit?

[kriko71]

Can I connect multiple hex in series like the pedal switcher and then control them using a commander? I'm looking to use 4/5 units in a rack setup.
Thanks

There is no real limitation... you should be just fine!

Be sure to post pictures of this rig!

Great! I'll post pictures once the system is done. Thanks for the fast response

While you can stack up a large group of MIDI devices, it isn't really recommended. It is very possible to cause latency, or drop/scramble information being sent to the next device. Think about the game "operator". The further it goes down the line, the worse it gets. A MIDI thru is not a pure path and it can cause issues the further it gets sent down the "chain". The best practice is to use a parallel MIDI Thru Box or MIDI "split". These units not only pass the information to multiple units in parallel but they also keep the signal clean and without any artifacts or minimal to no latency. We build systems for touring and studio musicians. One of the biggest problems we see and one of the worst reasons (as well as the simplest to avoid and fix) that there are people out there saying MIDI is so complicated/unreliable is because of the giant series chains people put MIDI signals through. One of the other reason for completely avoidable failures is not using different channels for each device or group of devices. We see musicians over and over again placing all or most of there devices on one channel and relying purely on multiple device PC's or different CC number values per device. This can cause major issues as well. Take the time to learn your devices and change each devices channel number whenever possible. Why have an incredible MIDI Foot Controller that allows for sending multiple PC's and CC's on multiple channels per foot switch and not take advantage of something that can make your system much, much more reliable. There are a lot of great companies out there that make MIDI splitters and Thru boxes. Make sure you do your research and get what you need system wise. If you need some recommendations, PM me and I'll be glad to help you out

Hope this helps you in your future system builds and thank you for taking the time to read this.

Not to be a bummer to what you are trying to do here valleycraft, but I would try it out with things routed in series before just throwing a MIDI Splitter in the path.
In fact, some setups require that devices be in series and will not work correctly with a MIDI Splitter. For example our Ground Control Pro sends a SysEx message that makes each switcher identify itself in the chain so they each auto configure themselves to respond the a unique set of Controller numbers. If a splitter were routed ahead of the switchers, they would all react as if they were the first switcher and you would not have any independent control.
