    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);

    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...

    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...

    Paul, What about creating a hardware LFO?...

    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...

    LFO using waveform object

    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...

    Filter LFO issue

    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...

    What if i'm already using the Dac output from teensy?(i don't have the audioshield)??. Is it possible to just have a function that internally modulates the frequency of the osc?

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