It's amazing that the iconic dance/trance clap (the clap after 1:15 in Acid Tracks) was forged alongside the 303. This exact sample (or an unbelievably similar one) could be heard throughout the late 90's and still features in many tracks today. It's the Wilhelm Scream of EDM.

Acid eventually resulted in liquid trance, which eventually became psytrance. Liquid was a fantastic exploration of the nature of sound, with many types of dynamics for a single instrument. EDM receives as lot of criticism for its lack of humanity and skill (regarding playing an instrument), but the same could be said of Beethoven or Bach: they were merely creating scores for an orchestra to play. EDM can be the same type of approach, only we now have ways to explore sound that simply weren't available to the great composers.
