Thanks @omjanger! I've just DM'd you back😊

One big question I forgot to include above: Might it be a good idea to split the ground planes for analog and digital, and then to star the grounds at a single point? Sources I've come across are about 75/25 yay or nay on this point. I guess it's really case by case?

Hi all, Last spring I began chipping away at the wild idea of a "Standalone MIDI Sequencing Drumming Glove", the current demo of which can be found at the bottom of that linked thread. A more apt title moving forward might be "Wearable Drum Machine" or just "WDM". I'm getting ready to pull the...

I've been busy with school and work, but just wanted to share an update since that last hazy post which was pitifully non-specific. Although I redid the enclosure in Fusion 360: ...it's still pretty large compared to the "glove" design I'm shooting for (Something more like this). To that end...

Thanks Paul! Glad to confirm this. Also good to know regarding the lack of this option on the T4.0

Maybe this is a dumb question. My goal is to charge and program the Teensy 4.1 through the same signal path as is used "out-the-box". Can I simply wire a microUSB-B cable's D+, D-, GND, and 5V lines to the correponding pins beneath the connector once I remove it? I've spliced a Powerboost 1000C...

I'm contemplating doing something similar with a T4.1 for an enclosure design with very limited space. I'd like for programming and power to be fed through this stock/primary micro USB connection. Am I okay to desolder the Teensy's micro USB connector, cut a micro usb cable open, and solder...

Maybe you've read this already / looking for something more discrete, but Mark's explanation here involves splitting a panel mount cable to program an externally powered Teensy without needing to sever the trace on the board itself: Although this^ does employ the use of another board -...

Thought I'd reach out as this will be my first time diving into PCB design/CAD software/custom circuit creation... I'm building a "standalone MIDI drum glove sequencer" doubling as MIDI controller, but for now it's codename "Chonky". So far feature-wise, it can record/overdub/loop up to 4...

Using a Teensy 4.1 & Rev D2 Audio Shield, I'm in the process of building a "Basic" standalone (no computer) midi sequencer which receives force sensitive resistor data and transmits ouput to a microSD card in SMF format. Working features are summarized here: - RECEIVES 1) Analog pin data from...

Solved the problem here Solved the "writing standard-midi-file format to microSD-card" issue this thread had been created to solve. Not so much a case of library inequivalencies as just pointing parameters in the proper order. Details are here...

Solved this! Just had myself thinking in the wrong circles. What I had to do was call the intermediary function "myNoteOn" using the parameters "note, velocity, channel" that I had used within "usbMIDI.sendNoteOn (Note[j], velocity, 1);". The intermediary "myNoteOn" just re-orders these...

Does midi.read(); detect midi information generated from within functions that are outside the main loop? Or similarly, does midi.read(); have to be in the same function as where the midi messages are generated? I'm trying to read FSR sensor input from Teensy 4.1's analog pins, send that to a...

Thank you @kd5rxt-mark, knowing that I’ll want to be comparing/translating the .h files is helpful! And thank you as well @PaulStoffregen, the rundown on Arduino, MIDI libraries, and Teensy’s development of MIDI is helpful as well. I imagine it was difficult writing Teensy’s USB MIDI to...

Hi @all, I apologize in advance if I violate any forum conventions here. If that happens I'll be sure to take note moving forward. Seeking to hopefully clear up some of my confusion: --QUESTION #1-- Does anyone know whether the order of listed parameters for these two libraries (<MIDI.h> and...

Update On "Standalone MIDI Sequencing Drumming Glove WIP" Thanks Daniel! Copy that regarding the function of your locators. I had a look at your project's video demonstrations, and that is awesome! I've made some headway on the INPUT portion of this project, and thought I'd share (CHEESY...

Daniel, Thank you kindly for your thoughtful reply! Just a bit of thinking out loud here... *Regarding 1A - Time Keeping: - I just read up on the IntervalTimer, and am still digesting the significance of "Volatile" variables and "Interrupts" as they relate to Arduino IDE code and...

Standalone MIDI Sequencing Drumming Glove (WIP) Hi everyone, I'm relatively new to the Maker community in general, and I've spent the past few months learning the basics of Arduino IDE, Teensy's various libraries, the core concepts of integrated circuit design, and working through the Notes &...
