Techno rhythms and percussion were produced by Roland Drum Machines TR-909 and TR-808.
Acid specifically refers to the use of the Roland TB-303, or any other synthesizer designed to emulate its unique sound.
Acid techno is a genre of techno that developed out of late 1980s Chicago acid house. Acid house was essentially house music made with a specific sound, obtained by using very distinctive instruments created mainly by Roland. While modern electronic instruments have memory banks of different sounds or patches, these machines had to be manually set by adjusting control knobs. The acid sound was obtained by either setting these controls to extreme parameters, or manipulating these controls in real-time as the track was being recorded, something record producers would call tweaking.
Electro (short for either electro-funk, or electro-boogie)is a genre of electronic dance music directly influenced by the use of TR-808 drum machines,and funk sampling.Records in the genre typically feature drum machines and heavy electronic sounds, usually without vocals, although if vocals are present they are delivered in a deadpan manner, often through electronic distortion such as vocoding and talkboxing. This is the main distinction between electro and previously prominent genres such as disco, in which the electronic sound was only part of the instrumentation.
