Behringer FCB1010

Bought in Octber 2021, eprom has 2.5.0 version. Using it to control ableton live performances at home for my cat.
Well build and quite heavy. To connect it to computer you need to buy a midi interface, I am using simple "doremidi" just like "Thomann Midi USB 1x1" which you can buy here too.
There are plenty of reviews of this device on youtube and also here on Thomann and I don't want to repeat it all, just point out what was not clear for me after these riviews before buying it.
It works perfectly with Ableton, each switch (except Exp pedals) can send cCCs and PCs and a Note and all at the same time which allows you to control much more than one device (if you really need it). Someone on youtube told that Ableton prefers midi notes over CCs. Actually both are possible but I switched to notes just to have same commands as my Launchkey MINI has. Programming FCB itself is a nightmare so I strongly recommend using a dedicated sofware. There are few of them and all have good youtube tutorisals, its up to you wchich to chose. If you know what a midi is and what you actually want to configure it will not take you more than a day so don't be scared by complexity of a manual.
Switch 1 and 2 at the rear panel are the exits to switch presets of your amp via standard jack cable, they are no designed to connect additional pedals etc., but you can actually expand your FCB by connecting additional midi controller (any and not only a pedal) to MIDI IN and instruct FCB to merge incoming signals from its own signals ant send them all thru midi OUT.
Switches are pretty tight and quiet, much better than round metallic click clack buttons cheap pedals have. But there is a lack of feedback so I am not sure which moment exactly the pedal is pressed.
Sadly UP and DOWN buttons are not programmable, they are not sending any midi comands at all. Probably next UNO chip will have this option, they have it on a wish list according to their website. I would love to use it to switch scenes.
That's all for the less than a month use. Due to low price I round up my rating to 5 stars. If you need it it's worth buying it. Thnk you Thomann.

I definitely recommend this product. It is insanely flexibility (basically can do everything) and has great value for money.
There are a few things, however, which I think the average user should be aware of:
1. This devices has no graphical user interface.
2. This device has hardly any limitation as to what you can make each key press do.
3. The combined conclusion from the above two bullets is: you need to actually program the thing - using it's hardware to do so. Remember setting the time in your old watch, where you need to press and hold several buttons in a specific order to get things right? so just like that, but with far more options, and with many more buttons.
I had to watch a 45min YouTube video that explains how to program the thing. As the instruction manual is simply not up-to-par, I recommend you do the same :
you learned the principals, it's quite easy to get going with, and the added value of this extreme flexibility is very much present. You can literally program any switch to shoot any MIDI signal(s) of many types and on many channels. I can't imagine something it can't do.

Also, and regardless, my specific unit produces a certain "hum" when it is on. Not a deal breaker, but could be better off without it. Might be a grounding issue.

Bottom line:
- HUGE value for money. You can do SO MUCH with it...
- VERY LONG learning curve. Expect to spend at least a few hours until you get the hang of it. I am a professional programmer with embedded systems experience and it took me about 4 hours to get it right.

Let me start with saying that Thomann's service and handling was flawless and I got my order in a perfect condition.
As for the FCB1010 itself - make sure you know what you're getting into before you get it. It is a very popular product that has huge dedicated forums with thousands of members, talking about it, fixing, optimizing, modding etc.
The build quality is exceptional. Its heavy duty (literally, it has its weight...) and as such feels solid and appropriate for handling a live performance on stage as well as anything you throw at it at home.
The biggest con is in its lack of a usb interface, meaning you have to use a midi-to-usb cable if you need that functionality, which was my main use case. Although it is possible to use 3rd party software to edit, upload and download configurations to the FCB1010, the 'official' configuration method is done within the device itself, and it takes time to figure out, especially if you've never worked with midi codes before. For me the best way to learn was watching an hour long youtube video explaining and demoing every setting, which just emphasizes how feature rich this thing is :)
