| br>The serial monitor that comes with the Arduino IDE is very basic and is mainly useful for debugging sketches. PuTTY, on the the other hand, has more advanced display features such as clearing the screen and displaying characters in bold and inverse. I modified my Cartesian 4x4 Step Sequencer sketch to take advantage of these features. I had to up the baud rate to 19200 so the redraw was fast enough. Even at that speed, you can see that changing the CV in real-time causes some glitches in the display. I'm using clips in Ableton Live to turn the ES-3 into a clock divider for this demonstration.
