yes, I've seen that example, indeed I tried something with no luck

USBHost myusb;
USBHub hub1(myusb);
USBDriver *drivers = &hub1;

...

const uint8_t *psz = drivers->product();
if (psz &&...

Hello, I would like to make some special function if a device is connected to the Teensy 4.1 though the USB host,
uncommenting this line in USBHost_t36.h shows the device name as 'product ' in the...

ok, solved it looking at the sendMidiNote definition, with 'cable' set to 1 (default is 0)


midi1.sendNoteOn(note, velocity, channel, cable);

happy new year to all ;-)

Hi friends, I'm facing a problem with Teensy 4.1 communicating with a Novation Launchpad mk3, this device has 2 midi ports (through USB)
I get correctly the midi coming from the Launchpad, but to...

I discarded that reverb because of that noise, haven't try to filter the output btw (got a filter in the input because low frequencies overload the reverb input pretty easy).
A better quality reverb...

did you tried with a different microSD cards?
as far as I know, modern cards are fast, but when reading/writing the data sequentially (which is great when recording video in high resolution etc), if...

Hi there,
I have a code (about 8k lines) for Teensy 4.1 which has a glitch, some times the machine freezes and the sound becomes a nasty blip for a second or so, I'm trying to figure out which part...

Hello, I have a question about using i2s_oct,
is this for a i2s IC (audio codec or DAC) with 8 channels or it could work with 4 stereo i2s ICs, sharing the LRCLK, MCLK and BCLK and using one TX...

Hi there, I'm having some issues with Teensy 4.1 and the pogo pins, made a PCB design which uses pogo pins to bring the USB connector to the front panel, but when the pogo pins are in contact, the...

thanks dude, you pointed the problem, it needs also this:


#include <Arduino.h>


now working fine, now I need to find how to make an array for all those samples, my first attempt with an...

The problem I'm facing now is that AudioPlayMemory object takes lots of ram for every added sample file, so I still have plenty of flash memory left, but with only 10 samples (converted with...

ey! thanks a lot for the info, I'm getting crazy trying to figure out how to manage this,
my idea was making a function in my sketch so the raw files in the SD card were copied to the flash memory...

Hi all,
working on a project with T_4.1 here, would like to know a little more about the flash memory on this board,
I've seen some detailed information about the memory on T_4.0 product page but...

Hi, may I ask, how do you guys control the distortion amount? with a mixer or amp before the waveshaper to change the input gain maybe?
would like to add distortion effect to a project, but I would...

Sweet Sixteen (eurorack module based on Teensy, derivative work from 16n),
16 channels of:
-midi & CV & i2C controller,
-CV to midi & CV to i2C converter,

I would like to use the Atmel AT42QT2640, are those libraries usable with Arduino/Teensyduino? because I haven't seen nothing 'open'

as far as I know the Teensy 4 processor does not support touch pins at all, so you can't use the touchRead library,
plus the Qmatrix allows 64 touch pads, which is way far of the possibilities of...

I've moved some variables, but also reduced some of them or deleted some unused ones.

This part is correct, the first variable is to read the button matrix, the second to compare with the previous...

well, I moved many variables that were declared as global to the main loop or functions, on every step things became more normal, first 2 tracks are not playing reversed anymore and everything is...

I'm doing nothing, just declaring variables, mo idea what malloc is...sorry...as I told my skills are pretty limited

i've just read something about this, probably I'm using too much global variables, will start modifying the code in that direction, also I've been using lots of byte or unit8_t to save ram but looks...

very interesting and useful information

Hi there,
I'm working in a 8 track sequencer, using Teensy 4 (which is amazing btw) The project uses a few big arrays (64 patterns with 8 tracks and 64 steps each) and I have arrays for the...

the audio tool does not support arrays of objects, but you could manage anything done with the design tool making an array of pointers,


AudioSynthSimpleDrum drum0; //xy=219,42...

ok I misunderstood the fact that the DAC does not need a clock with being a master i2s device,

'The integrated PLL on the device removes the requirement for a system clock (commonly known as...

Hi people, just got the boards for a project with Teensy4, the DAC for the audio part is a PCM5100, which should work as i2sslave device but I get no sound,
I've tested with a few examples from the...

thanks a lot for the answer, must try this and see how it works

hi, I'm working in a multiple LFO eurorack module with cross modulation, sadly the AudioSynthWaveform does not have a read(); function (like AudioSynthWaveformDc has) so if I want to control the...
