A question for all the music-making pros out there... what in the world does the "808" or "909" mean in some of the sample names? I'm DLing custom samples and they are described like: "A synthy 808 snare" Is there some specific quality or tone that makes 808 or 909 different from normal sounds?
808 stands for the TR-808. Transistor Rhythm - 808 Drum machine made by Roland. 909 is the same, but for a different style drum machine Roland made. The TR-707 is a 'baby' version of the TR-909 with mainly sampled sounds instead of real drum synthesis. The TB-303 is a Bassline synth made by Roland it stands for Transistor Bass - 303. It's the squelchy wormy synth that created the Acid House sound. Used in a lot of Techno/House/Trance etc.
To put it short, all Roland drum machines from the 80's.
