Play 6 different notes Controls: arrow keys space bar mouse click Image source: http://www.freeimageslive.com/galleries/sports/music/pics/piano_octave.jpg This project uses the built-in MIDI synthesizer, rather than samples. I've noticed this is better in terms of latency (i.e. less delay between pressing the key and hearing the sound). However, it also means that the sound may be different when played on the Scratch website than when you download the project and run it on your local machine. At least on my Mac it sounds kinda like a proper grand piano, whereas the Scratch website produces a bell-like electric piano sound. Any ideas how to work around this, i.e. how to get a nice piano sound on the online version?
