You are reading the RMS result thousands of times a second even when it is not available. Try changing your loop function to this: void loop() { if(rms1.available()) { x = rms1.read(); if(x != 0.0 && s ==...

I've not been able to find one for the M7 so I have presumed that the M4 info is a lower bound on the performance of the M7 :) Pete

This webpage has a description of the FPU instructions and their timing. There's also a PDF version of the M4 DSP instructions. Pete

I tried your code with an M-Audio keyboard which has a modwheel. No matter how much I roll the wheel and play chords and arpeggios, the total note count is always zero at the end. You didn't include your...

Your code in #3 compiles for me with no errors. But I am using Arduino 1.8.19, not 1.8.16, and Teensyduino 1.56. Pete

#define LockB 35 #define LockLed 30 These two pins are on the bottom of the T4.0. Are you actually using them? Looks like you have spare pins on the top which would be a lot easier to use. Pete

Artnet.h #includes Ethernet.h which conflicts with NativeEthernet. Don't know how to fix this but I would try meddling with Artnet.h and where it references Ethernet, change it to NativeEthernet. Might work. Pete

You need to start debugging your code. Pete

No it won't. You've fixed the index but you can't treat queue1.readBuffer() as an array. You have to save the address in a pointer and then use it as I showed in #12. Pete

Can you also post photos of the underside of each Teensy? Pete

(float)(queue1.readBuffer()) This won't work. readBuffer returns the address of a buffer, if one is available, and returns NULL otherwise. Using 'i' as an array index will also fail because it will have very large...

You aren't using the most recent version of the Arduino IDE and Teensyduino. The version of Teensyduino you are using does not have the play() function in the Audio library AudioPlayQueue. You should upgrade to Arduino...

Can you post photos of the two Teensys? Pete

It's not clear to me what the hardware setup is like. Do you have two completely separate installations, one works and the other doesn't. When you exchange the T3.2 between the two setups, the problem switches with the...

What do you mean by "firmware reference"? The firmware is your code. Distinguish which one from which other one? If you mean the T3.2, they should be the same. If you mean the code in each T3.2, you can't get at...

Did you buy them all from PJRC? Pete

And the code @defragster used on a T4.1 also works on a T3.2 Part of the problem may be that you are running the most recent version of Teensyduino on a rather old version of the Arduino IDE. The current version of...
