    One of the benefits of the current in-the-browser approach is that the user doesn't need to download or install anything. They just open the link in the browser. That's a really nice feature. I wouldn't give that up...

    Echo'ing what WMXZ already said, my main issue is that emulated serial doesn't work outside of the Arduino Serial Monitor that is my biggest issue. Additionally, I also have a problem caused by me having some custom...

    You're running with a lot of audio objects. Might you be running out of CPU? Which teensy are you using? And, when you asked what the memory usage was, did you also ask what the CPU usage was?

    And, any chance of the non-emulated MTP Serial option (direct from the WMXZ repo) being folded into Teensyduino instead of the emulated serial? There are certain serial interactions that break when using emulated...

    What is the thinking on a release date for 1.54 (not beta, but actual release)? The inclusion of the Greiman SD in teensyduino is a game changer for me with my Tympan stuff. It's a huge leap forward to have it in...

    Thanks for the extra work. No need to check my example (unless you are interested) as it worked well enough for my needs. I was sharing it in case others had similar problems. But, now that you've provided...

    When I was trying to get it to work, I did try turning USE_EVENTS to zero. It didn't seem to work...but I was having multiple issues, so USE_EVENTS not solving my problem was probably my fault and not a problem with...

    I'm trying to use the latest WMXZ MTP library with Teensy 3.6 and Teensy 1.54 Beta5 (with Arduino 1.8.13). The included example sketch mtp-test.ino won't compile. After a whole bunch of repeated warnings about Time.h...

    Nice catch! I didn't realize that the N_k was the *time*-domain window used in computing the DFT. I incorrectly assumed that it was the frequency window used for frequency-bin summing. Ooops! Looking more...

    So, yeah, if one is looking to see how many bins one should sum together, that equation shuffles around to be: N_k = (Q * f_s) * f_k As the Q is constant for all filters (by definition of constant Q), and as the...

    Isn't logarithmically increasing bandwidth (to follow logarithmically increasing center frequencies) the same as constant Q? Or am I misunderstanding constant Q? I characterize the FFT approach as an approximation...

    Their algorithm looks buried in WebAssembly, so I can't see what's going on. Did I simply miss their algorithm? Or can WebAssmebly be decompiled into something human readable?

    The number of bins that you sum will be proportional to your center frequency. So, at G3, you might have just the one bin. At G4, you'd sum 2 bins. At G5, 3 bins. etc. That's how one can approximate a constant Q...

    While we do all agree that the FFT approach is probably superior to a bank of 96 parallel filters, do be aware that the FFT approach more clearly exposes the inherent trade between frequency resolution and time...

    Personally, I like using Arduino/Teensy to *add* functionality to old synths. Back when I got my Korg Polysix, they were pretty undesirable and inexpensive due to the leaking battery problem (and due to its...
