Yeah, tried different things, can't run it either :(

Okay, wait... Maybe i'm still using the original audio library! Should i just replace synth_waveform.cpp and synth_waveform.h from the original one? thanks

Thanks John-mike, I'm trying to do it with my sketch but looks i can't make it work Plus i don't know what to do with this part: AudioConnection patchCord1(waveform2, 0, i2s1, 0); That's the waveform object that's we are applying FM right?, it could be routed to a mixer or something...

Paul, I think you mentioned this in another thread. I wouldn't mind if it's every 2.9 ms (going through the adc or internally) I just want to learn how to take the oscillator data (lfo) read it and then apply those values to the freq of my oscillator. I don't mind if it's perfect, just wanted...

I'm currently using a Teensy 3.2 and using the DAC for audio output (have a capacitor and probably will build a filter for unwanted frequencies). The dac is used for the synth output, I do not have an AudioShield. I just want to create an external LFO that can be read by teensy to control osc...

Paul, What about creating a hardware LFO? What kind of circuit can produce a sine or pulse with an amplitude control so I can later read it somehow with teensy via the analog Inputs or the ADC?

Since i wrote this post i was able to do AMP - Volume modulation. I used a multiply object, connected to the main synth signal and to a mixer with a dc object and a waveform object. Got some help over there on the internet. Both running at an amplitude of 0.5. I post this if anyone needs it...

Hi All, I want to have an LFO to modulate the pitch of the waveform object or the volume of it(via the mixer). I know you can do this with the sine-fm osc, but i need it to be a waveform object because i have more waveform types. Here's what i know: -I can use a waveform object as LFO and use...

I've also realised about this, that at some freq/res values I could have problems. I did some things to fix them like using IF conditions, if it reaches a specific freq value i'll just limit it, but i thought it was a problem on my side so I tried to make it work with that value(19khz). I will...

Hey, thanks for your answer, I will try with other pots....About the frequencies I was just using 19khz because 20khz is the human limit for hearing right?, maybe i'm just confused. Could you explain to me why it has to be lower?? Thanks again!

Hey guys I'm building a basic synth and i already have 2 osc, a filter controlled by a waveform osc to act as LFO. The 12 bit dac is used as audio output. I'm just starting to understand audio programming so everything is quite new to me. On very specific values , like Freq : 19000 and Res 0.9...

So, i need to generate a wavetable of a sine or square ...put it into an array ...and then? Where do i get the values for these wavetables? can i just download this data from other examples? And also, after i have the wavetable , how do i connect the oscillator freq to the lfo? Many questions :)

Paul, even if it's not that accurate, is it possible to do this? i'm just trying to build a simple LFO(to pitch) for a waveform osc. I just don't know where to start i would really appreciate some help. Thanks

Thanks, i will give it a try!

Do you just plug in the capacitor to the dac pin?, does it have to be a specific one?. Cheers!

Great, as i'm just getting started it seems that there's lot's of details involved with the audio output and now i can understand why the audio shield is recommended, it's a shame that is not that easy to get one where I live(South America).

I'm also thinking about this, for now i only have the dac connected to an output(dac pin and gnd). I know that this could lead into dc offset issues and some extra unwanted frequencies. Getting the Teensy compatible audio shield is the solution, but i also want to learn how to build a proper...

Thanks for you reply Roel, i will try this. I did some more testing and it looks like it's working now. Just one question when i do analogReference (INTERNAL/EXTERNAL) i have to set it up to internal to have a proper volume, on external sounds very low. Whats is this doing internally? and how...

Hey, I'm just getting started with Teensy and i've tried some very simple things, I created an oscillator(waveform->saw) but i can't control the volume of it, or at least i can't tell any difference when i change the values from the mixer or from the osc. Please find attached a picture of...
