Hello mates. I have some questions regarding the sound order.

1. Using SOUND, you can play one note at a time. If you are having a chord, say c-e-g, could you emulate that by sending the single notes very fast after one another, so cegcegcegceg and each chord a fraction of a second.

2. Can you use SOUND via Transistor, too?

So instead of

Pin --- | | --- Speaker --- GND

this

Pin --- | | --- Resistor --- Transistor --- Speaker --- GND, by using a emitter follower.
