thanks for this prompt answer
Event with a very simple render like
for(unsigned int n = 0; n < context->audioFrames; n++) {
// log on the scope
scope.log( context->audioIn[n * context->audioInChannels]+context->audioIn[n * context->audioInChannels+1],
analogRead(context,n/gAudioFramesPerAnalogFrame,0),
analogRead(context,n/gAudioFramesPerAnalogFrame,1));
}
And the capelet activated from the IDE (here with 2 inputs)
I get some visible input on the scope for the regular audio, and channel 1, but not for channel 0 (even if I switch inputs of channel 0/1)
I can see (or hear with another program) the signal only if I touch the piezo, so the signal is here, but very low.
Here are 2 pictures, but it is late here, no sun light, so the quality is not that good. I can't see anything special on my side.
