The TB-303 was a simple monophonic synthesiser with built-in digital step sequencer relased by Roland in 1982.
It only does one thing, namely playing acidlines with plenty of sliding and accents, and it does it extremely well. Its contorted screams form the basis of a whole genre of music, acid house, and often elevate more than a few others.
When taking centre stage, it works even better through a distortion or overdrive effect, such as a Boss ROD-10.
I gave Pierre my TB-303 because I was just tired of using it, I didn't like it anymore. The big difference between me and Pierre was that he was a DJ and I wasn't. He made the mistake of telling all his DJ friends that it was a TB-303 on "Acid Tracks", so next thing I knew, within four months there were about sixty acid records out, and within five more months there were over a thousand — just in Chicago!
— Marshall Jefferson, 1989
The people who made the Bassline must have been mental to make it do all that it can do. They can't have thought "That's too much, that doesn't sound like a bassline." They must have been into acid music already!
Alexander Robotnik's "Les Problemes D'Amour", released in 1983, was a huge "progressive" hit in Chicago, selling around twelve thousand import copies. A few years later, house producers, already enamoured of Roland drum machines and synths, started messing around with the 303, discovering applications that the manufacturers had never imagined.
Simon Reynolds, Energy Flash, 1998
I wanted to make something that sounded like things I'd hear in the Music Box, or I heard Farley play on the radio. But when we made "Acid Tracks", that was an accident. It was just ignorance, basically. Not knowing how to work the damn 303.
— DJ Pierre, circa 1999
On most of the tunes, the 303 and the bassline were the only things that were actually played in a traditional way. The rest of it was gross manipulation of samples... It only had four knobs to twiddle. You could learn the permutations of what happened between the four of them. And the great fun was that you did it all live.

The TB-303 uses a 4-bit NEC μPD650 microprocessor, and three NEC μPD444s for a combined 3072 nibbles of RAM.
In MC-8 and MC-4 terms, you can think of the TB-303's accent and slide as two MPX (Boolean) outputs. The timebase (clock resolution) is 48 (based on a 24 PPQN clock, but noting the downticks as well as the upticks). Each note, being a sixteenth note, lasts 7 ticks, with a 5 tick gap, unless it's sliding — then it lasts all 12 ticks. Each rest lasts all 12 ticks. This makes for a very simplified MicroComposer, which allows you to enter notes through a more intuitive interface, at least by MC standards.
