Hi, I've had no issues with the codec so I suppose the codec, schematic and layout are ok. For the files try this link For now I don't use the board I'm working on something else. Have you already started designing your synth or you are in the brainstorming phase ?

Hi ! I try to detect the peaks and the time of the peaks for a bass whose amplitude is modulated by LFO's. I first tried with the peak object by sampling the input several times in a second. The result is it seems like I get the green values shown in the picture below. I think it is normal...

Hey ! The board is working :). I add some stuff to the original schematic. Now I have the codec, 24 pots + 1 for volume control, 1 rotary encoder for the menu, a ILI9341 display, line out and headphone, midi in, thru and out. The Teensy and the display are mounted on socket so it can be plug...

So my 30MHz Digilent Analog Discovery 2 USB oscilloscope is totally useless for this ? I wanted to try different resistor values by soldering and desoldering until I get a good trace (no ringing, no overshoot, no undershoot). Another question : I didn't connect CLKOUT as I will use the codec...

Hi ! :) I’m designing a synth and I need some help for reviewing my schematic before starting the layout. The things I’m not really sure about are : Is the CODEC compatible ? I’m not using any inputs (neither MIC nor LINEIN), only line out and headphone out, but the “AudioOutputI2S” object...

The problem was more me not knowing a TRS audio jack is not intended to be put in an XLR connector. First time using the inputs of an audio interface.

Found the problem, haha... A male TRS jack in a female XLR input won't work properly... Now I'm using a male XLR cable jack, problem solved. Shame on me... So the problem was not the teensy or the DAC or my audio interface but the cable.

I connected the Teensy to the line input of my laptop and I get a clean sinewave in Audacity. So this is my audio interface causing the problem.

The waveform looks like a 440Hz sine wave with harmonics/noise. It should look like 440Hz sine wave without harmonics/noise.

Hi, I have a Teensy 3.6 and a PT8211 DAC. I uploaded the PT8211Sine sketch and outputted the sound directly to my amplified speakers. The sound is nice and clean, no problem. Then I connected the audio jack from the DAC to one of the input of my audio interface (Behringer UMC204HD). The input...

Interesting ! Actually I decided to keep going with Mozzi. I already got 80% of the code, don't want to start from 0 with Teensy. But next synth will be Teensy for sure.

Must try it. Sometimes I need breakpoints, not always easy to debug with Arduino Serial.print().

Ok thanks Paul :)

Thanks Paul. It will be possible to use the objects of the teensy audio library inside the Arduino IDE ? Or is it just for compiling Arduino code on Teensy board ?

Hi ! I'm currently building a synth with Mozzi on a Arduino Nano. The 16MHz clock speed quickly became a problem and the memory is almost full now so I can't really keep going so I decided to look at Teensy. The boards look amazing, tiny, powerfull and not expensive. The problem is that I want...
