Hello. I have a huge sketch for a groovebox. I have a problèm writing waves samples from the sd car to the psram as soon as my pin 0 is used in my sketch. I need it to wire my midi input. Midi input is working nicely. But when i use it in the code the data don t write to psram but if i disable...

hi, I built a midi controller for a friend but he broke the micro usb connector on the teensy 4.1, I m not sure if I can replace it using the D- and D+ under the connector and also vin and ground to wire it to an external usb connector, I read on some post that it will work and other that it won...

I ll try this thanks!!! All the rest of the normal t3 library work the same way as the original? I alreday have done dews things that took me long time to achieve and I d like to be able to use it without modifying all my code

Yes exactly that should be perfect for my project!!!

hi, I need to draw something on my ili9341 on teensy 4.1 to display the value of my midi cc coming from Ableton Live, I use ili9341_T3 library that doesn't have arc drawing capabilities, I doesn't t have the knowledge to do it myself, anyone as a solution for me to do it please? i d like to draw...

i made change in the code when I was able to get others values but can t remember what did I changed... I m lost with these piezo :-) maybe my piezo are not the good ones?

thanks for help!! with this code I get in serial monitor even if I strike the piezo quite slowly or very hard begin peak track 1023 peak = 1023 begin peak track 1023 peak = 1023 begin peak track 1023 peak = 1023 begin peak track 1023 peak = 1023 begin peak track 1023 peak = 1023 begin peak...

hi, thanks for answering! the values I got are voltage not velocity, I was able to receive 354 or 738 or 1023 as voltage but the values sent always the max velocity, what I d like to achieve is using 2 piezo for the moment that send different velocity over usb I m a beginner in coding I can t...

hi, now I can get values of 354 or 738 or 1023 in serial monitor but the velocity sent is always at 127 anyone got idea how I could make this drummed working with velocity please?

hi everybody, I come to midi with piezo for the first time, I just tried the code that odds-on gave my teensy 4.0 seems to always send 127 for velocity, I wired my piezo to A0 and A1 with 1M resistor and also tried with 100k and it s the same, I don t have the diode here, may this be my problem...

thanks a lot I found my problem of routing! I ll be able to go to the next step!

hi, i m still on my dub siren project, I restarted my project from scratch to be sure to really understand what I m doing after lot of time looking to existing codes. i was able to make an lfo acting on filter frequency but can t make it work on the pitch of my waveformmod oscilator, can someone...

in fact with my dub siren i want the sound to be played then note stop and goes to the delay feedback and I want that only the delay continu but not the original note http://rdh-hifi.fr/fr/8-post/24-dub-siren-kit here you can see a dub siren analog in action, it s that I d like to reproduce

and how the note will be stopped? note on and note off are the only part of audio library I really don t understand for the moment, for this project I studdied some other teensy synths but no one was using a push button on board they were all only midi i ll try to remove that and see! thanks! if...

hi, again me with a question, i m building a dub siren with teensy, I have a pushbutton for noteon few waveforms, 2 lfo, a reverb and a filter my problem is when my push button send note off it cut also my delay feedback but I want that feedback to continue when note off is send, here is the...

thanks for all your suggestion! my teensy was already used for prototyping my first midi controller project and I certainly made mistake as a beginner, it s not impossible that I ruined it with my experimentations!

I tried with each analog pins and they all have the problem, toi made lots of experiment with this teensy and audio shield and already desoldered and resolve red the shield on it I think I broke it! I l Gina order a 4.1 and the rev d audio shield to restart this project!

it seems that my teensy as a problem, the other one used for the synth doesn't react the same way!

ok so I tried with a minimum of code and same result!! void setup() { // put your setup code here, to run once: } void loop() { int cutoff = analogRead(A3) *20; //analogReadAveraging(10); Serial.println(cutoff); delay(100); // put your main code here, to run repeatedly: }...

i m using the pin 17, with analoginoutserial I get the same result :-( i have the audio shield wired on the 3.6 maybe that can be a problem? I didn't thought about it!

yes it s linearly I can reach each voltage when turning slowly the knob. but when I come under 2.89v serial print show 0 as value

I got 3.28 fully open and 0V fully closed

i wired vcc to the 3.3v pin on the teensy 3.6

hi so when I turn the knob it print on serial monitor 0 or 20460, nothing else between these 2 values my pot is wired one pin to gnd one other to vcc and the middle pin of the pot to my A3 pin on teensy and it s a 10k pot

I still have the same problem, maybe there is something else wrong in the code?#include <Audio.h> #include <Wire.h> #include <SPI.h> #include <SD.h> #include <MIDI.h> #include <SerialFlash.h> #include <Bounce.h> // GUItool: begin automatically generated code AudioSynthWaveformDc dc1...

hi, so I just tried with map filter1.frequency(cutoff); cutoff = map(analogRead(A3),0, 1023, 0, 20000); but I still don t have the total range of frequency with my knob, it cut sound at around the half of the pot sorry for my approximative English :-)

Wow thank you very much for your help!!

Thanks for you answer so if I want to have a response from 20khz to 0 when fully closed how could it be written please? I learn code since few month but I learn alone and it s not very easy!

hi, I try to ad potentiometer to an existing code of a midi synth, I start to ad a potentiometer to the cutoff but when I turn the knob the filter is closed at the middle of the potentiometer, any one can help me or show me the good way to ad potentiometer please? #include <Audio.h> #include...

oh damn i understand my problem, my f.... breadboard has a problem where I wired the enveloppe button! I ll be able to go forward now!!

hi thanks for the answer, I saw this already, I m watching the tutorial too, but in the exemple it show how to trigger samples and I d like to trigger the waveform

hi, I try to begin to understand the audio library, can someone help me to simply play the sound of the waveform example with just pushing a button, in the exemple the sound play by himself and I d like to trigged it with a button instead, sorry for the noob question but still beginner in code!

Thanks a lot for the answers!!!

hi all, i m a beginner in electronic and I d like to add a USB Host capability to the midi interface of my controller, Paul told me on Facebook that I have to add a tpd3s014 to my schematic but don t know how to wire it, can someone help me with it please? here is what I done is it good? do the...

hi, thanks for your interest, I have been very busy these days didn't have time to comeback here, it seems that it s too difficult for me to achieve what I wanted so I ll try to use analog read instead but it s very difficult for me!! I look on internet to find good tutorials to do it!

here is the code I try to make, there is the synth and the controller and I d like that my pots on the mux to control all the variable with the same midi cc that for the midi usb as they where in the code I modified #include <Audio.h> #include <Wire.h> #include <SPI.h> #include <SD.h> #include...

Thanks for your help! I thought that it could be fun that my pots send midi out at the same time, it could allow us to record movement in a daw, I also wanted midi cause I m a real beginner at coding and I already achieved a midi contrôler so I thought I could use the same library for coding...

Sorry I wrote something really unclear :-) I wanted to tell when I turn à potentiometer it send midi to my code.

hi, i d like to control a synth project with pot on the same board as the code but via midi, can someone tell me if it s doable and how to achieve it please? do I need to creat to midi interface? how can I tell a pot to change value to a variable over midi please? i have my synth code working...

i start making my code, do you think I m on a good way to declare button and potentiometer? does including the playsynthmusic.h will allow me to play midi notes according to fréquemment? it s what I thought I understood. ```cpp // Waveform Example - Create 2 waveforms with adjustable //...

thanks, I have never seen that function were explain a little bit here! I ll try to understand a little bit more with it! thank you very much! i ll check if I find a way to use midi input

hi, i m new to world of programming, can anyone send me a link where I could learn how to use teensy audio library please? I already read the workshop tutorial but I need more basic knowledge by exemple learning how to receive midi note from my controller and learn to implement controls to mixer...
