The Beginning

The Roland TB-303 Bassline Synthesizer was the result of Roland engineer Tadao Kikumoto. The 303 is a monosynth, meaning it only makes one sound at a time, compared to a poly synth which could make several sounds simultaneously. When it was first released in 1981, it was largely written off as a failure due to its difficult-to-use sequencer, tacky synthetic sound, and low price. It was one of the first programmable monophonic analog synthesizers and was designed to emulate the sound of an electric bass guitar, however its rise to fame did not come from its intended use.

Key Features

The 303 was extremely influential in the development of electronic dance music, and it was the key ingredient in the creation of  classic acid house and techno tracks. It also served as an inspiration for the modern day synthesizer, inspiring manufacturers to build devices that could achieve a variety of timbres. Featuring only one oscillator and a single resonant filter the 303 doesn’t need much more to stand out. It also has a feature called accent, which could be used to add emphasis to certain notes and help the bass line stand out and create that signature sound associated with the  acid movement.

Along with accent the unit has a tie feature which causes the notes to blend together in a unique way similar sounding  to raising the portamento on other synths. The 303 uses  a unique 16 step sequencer and a 24 dB low pass filter. It also has an Analog Digital Conversion (ADC) circuit which allowed for a wide range of timbres.

With only a sawtooth wave and a square wave other synths can have a similar feel and sound however there is something very special and noticeable once you have put the the time in to listening to an original.
