- It can process the voice effect or play back WAVs (and can do both within the same sketch), but you can’t do both simultaneously.
- You can’t read other analog inputs when the voice effect is running (case in point, you can’t alter the pitch continually with a potentiometer). If using analog sensors as sound triggers (e.g. force-sensing resistor pads in shoes), consider work-arounds such as using a carefully-trimmed voltage divider to a digital input, or a second MCU to process analog inputs, forwarding triggers over a serial or I2C connection.
