View Full Version : MIDI Lfo with audio lib

Hi. As I mentioned in a previous thread, as a part of a project, i'm making an lfo. At first I didn't use the library, made the lfo manually, but it was a bit complex and harder to read, so I went with the audio lib and I made it with the waveform object.
Thing is, I need to send the lfo via midi. With the first method(without library) I could do it, because I just used the variable to write the DAC and use it in the control change message(slowed down) but now with the audio lib I don't have the variable for use.
Is there any way that the waveform object could return me the amplitude? So I can use that variable to send the lfo via midi.

If you use the queue object, you can get the waveform output data back to the sketch.


Keep in mind that the audio information is updated much more quickly than the MIDI baud rate. MIDI would only have time to send a handful of values from each buffer received from the queue.
