Hi
I found the mistake. Unfortunately I have used pin 8 twice in my test setup. Therefore there was a conflict.
Now I have corrected the setup and everything works fine.
Hi @mjs513
It seems that the issue is wider than expected while using Adafruit WiFiNINA.
Can you check, test to see if this is an SPI conflict / bad SPI-related design (seen with many SD cards) by using SPI1/SPI2...

Hi,
I am looking for fast fourier transform on streaming audio input (analog). Can the audio shield do this and do I need to wire in an input to specific pads?
Thanks,
@mjs513,
It seems that there is some severe issue when using T4.1 + Featherwing + even Adafruit WiFiNINA; now you have to check if we still have the same issue with any other board you have (SAMD, nRF52, RP2040,...
Here's a version that is designed for QNEthernet. I took out the #ifdefs for readability and added a few notes. (Hopefully I didn't make any mistakes.) There's a few other ways to do things here, this is just one way.

Following up, quoting myself
Got this idea to work. mentioning as the strategy may be worth looking at to slow large amounts of sysex for older synths.

Write a test code to test your electronics. We don't know how the 12V may have damaged everything else. The very least, find a way for 12V to not be accidentally wired to a Teensy pin. This could involve optimizing your...
Arrrggghh! Thanks defragster. I was hoping it would be the opposite. I'll start checking downstream of the logic chips. Better pull out the schematic.

I don't see any problem with long sysex messages. Like the MIDI Sample Dump Standard you can send samples.

I wanted to be sure, so I've checked the official Yamaha documentation. See page 37 here :

Greetings Rolf
Found this on Arduino boards: rugged-circuits.com/10-ways-to-destroy-an-arduino/
perhaps this or other things apply - given 'some signs' of catastrophe in the package seems all safety margins and components violated:
Yes. Your SysEx data block is too large. With MIDI-OX a maximum of only 2048 bytes per SysEx block can be received.
Such a large block of data is not normal. All synthesizers I know send a block of less than 500 bytes...
Since most of the questions here are quite intelligent, let me ask a stupid one.

It's a dump of a DX7 bank with 32 patches inside. So the file actually already has only one F0, then 4102 bytes, then one F7 at the end.
