Hi, This is my first time posting here. I'm having an issue trying to build a polyphonic (paraphonic technically) synth using the WaveformMod object on a Teensy 3.2. I am trying to get the polyphony up to 32 voices, but when I get past 16 voices I start getting glitches in the audio. Some of the voices won't play, while others sound like they are being frequency modulated in a weird way. Is there a limit to the number of WaveformMod, envelope, or mixer objects that the Teensy 3.2 or Audio shield can handle?
Any ideas as to what could be causing this issue, or suggestions for how to fix it? I appreciate any input.
Here is the code:
#include "note_frequency.h"
#include "scales.h"
#include <Bounce.h>
// 15 = 15 ms debounce time
Bounce button1 = Bounce(7, 15); // change waveform
Bounce button2 = Bounce(6, 15); // change LFO destination
Bounce button3 = Bounce(26, 15); // Hold/Release
Bounce button4 = Bounce(24, 15);
// The circuit:
// - LED attached from pin 13 to ground
// - pushbutton attached to pin 8 from +5V
// - 10K resistor attached to pin 8 from ground
const int buttonPinHold = 8; // the number of the pushbutton pin // Hold
