Here's a "quick & dirty" program that you can use to test your EEPROM reads/writes in a predictable & repeatable way:
USAGE NOTES:
1) WRITE known (random) byte values to the EEPROM
a) uncomment the line that...
I don't see anywhere in any of the EEPROM examples that indicate a limit of 512 (did you actually run any of the T4.0 EEPROM examples in the Arduino IDE ?? What example are you referring to ??).
Although I haven't...
Sorry, apparently my phone corrupted the pasted thread link . . . it's <here>.
Note that one of the posts in this same thread seems to imply that the output from the 6n137 is inverted from the normally used 6n138...
SteveCS:
Searching the forum for 6n137 finds several threads, including <this thread>, which appears to describe a successful implementation with the 6N137.
Hope that helps...

You posted in an area with T4.0 in the subject line, but you seem to indicate that you are using a T4.1. You can look <here> for a comparison of Teensy Technical Specs (including EEPROM sizes for T4.0 & T4.1).
From...
@asclepias:
There are a few MIDI examples, which are available from the Arduino IDE...maybe these will provide some needed help.
Click on "File", "Examples". Then, under the "Examples for Teensy 4.1" section...
On the question of using EP1, refer to <this> post by Paul Stoffregen, which indicates that EP1 is RESERVED. Hope that helps . . .

If you suspect a crash/lockup of some sort, add the following at the top of your loop() function (The version proposed by @KurtE can be used to make sure that you have time to read the report before the Teensy reboots):...
@Taymar:
Yes, you should be able to test at different rates with the changes as you have shown. Good luck & feel free to ask any other questions that may come up.

When I first started tinkering with the Teensy 4.x CAN capabilities, I found a recommendation by PaulS (see <this> post elsewhere) for an inexpensive CAN analyzer that proved to be an immense help in troubleshooting my...
@rvh:
See if <this recent link> addresses the answer to your questions . . . from your comments, you're concerned about using a lockable T4.1, but you didn't say whether you plan on locking it for sure or not.

What is a "FlySky FS-1A6B" ?? Do you have a link to the hardware and/or specifications of the device ??
More info will help others to help you !!

@Stefan:
In general & from my experience when I've asked questions in the past, most of the experienced members on this forum are very good at answering questions for which either they have some direct experience, or...
It appears that you should remove the connection between TFT pin 3 (CS) and Teensy pin D10, then replace it with a connection between TFT pin 3 (CS) and Teensy pin D14. Everything else appears to be correct.
Let us...
Here's what I successfully used for a previous version of my TeensyMIDIPolySynth. This particular version included both the PJRC 320x240 ILI9341 TFT touchscreen & the Rev D Audio Adapter on a T4.x:
