Wireless/BT/WIFI Multiple devices for midi

I’m looking for a solution with the following requirements:

I need multiple devices to talk simultaneously (both directions to each other) with 32 or more devices, at or above midi controller speed of 31250Kbaud

the small devices will be sending midi data to a single arduino/transceiver, which needs to be able to send back a few control commands to all the smaller devices, for example to change light colors on the smaller devices.

range needs to be 50 feet normally, but 100 feet would be preferred.

any suggestions? I don’t care if it’s Bluetooth, Wireless, or WIFI…

But it does need to be Arduino compatible, small (teensy?), and cheap…

Thanks for any suggestions I might receive…
