Need help building a diy organ console

Hi,
I'm a newbie in diy midi controller and I wanted to build an organ console with 3 keyboards, a pedalboard and many buttons. For the keyboards I bought 3 m-audio keystation to disassemble them and use there own electronic so it would be easier for me since I'm a newbie so it was just more convenient for me.
For the pedal board I bought one from an old organ that I "midified" using reed switches and a Teensy 4. I first wanted to go the easiest way to me and do 1note=1pin but it's rly not convenient.
Also for the whole thing I would end up with 4 different midi device (3 m-audio and the Teensy) running into a USB hub into my computer and I started to think that it would be way easier if all the keyboard and buttons would act like a single midi keyboard but for example too keyboard is chanel 1 then 2 etc...

Is it possible to connect those m-audio keyboard on a Teensy and "reed" them ?
If so, how can I put so many different input into a single teensy ? I heard about matrix but I genuinely didn't understand how it works and I didn't find easy to understand tutorial yet.

I'm open for any type of help at this point xD
 
If I understand correctly what you are saying, it seems that you have three commercial MIDI keyboards. If they each have a standard USB interface (e.g. USB cable connected to the keyboard, which then normally plugs into PC), then you could plug a USB hub into the USBhost port on your Teensy, & plug the three keyboard cables into the hub. You may face some challenges being able to uniquely identify the notes from the individual keyboards. If the keyboards have the capability to change which MIDI channel they send their note commands over, that would make things much simpler for you.

Hope that helps . . .

[edit] P.S. Take a look at the Teensy MIDI examples which are accessible from the Arduino IDE. Things will be much easier if you start with a single keyboard & get that working first, then add the other keyboards & pedals. MJC

Look at www.kinkennon.com for examples of MIDI boards for Virtual Pipe Organs. There are free schematics and Gerbers so you can have boards fabricated and the SMT components added from firms like PLCPCB. The circuits use the Teensy 4.1 and have proven fast and reliable. An encoder with ethernet connectivity is available for networked applications.
