Home > Roland TB-303

 
The TB-303 was a synthesiser/ sequencer produced by the Roland corporation in 1982 and 1983 that had a crucial role in the development of contemporary electronic music. The TB-303 (named for " Transistor Bass") was originally sold to guitarists for bass accompaniment when practising alone, a role in which it failed miserably. Production lasted approximately 18 months, resulting in 20,000 units. It wasn't until the mid- to late- 1980s that DJs and musicians in Chicago found a use for the machine in the context of the newly developing house music. Phuture's " Acid Trax " is widely acknowledged to have been the first track to incorporate the sounds that have come to define the sound the TB-303 is known for today. The well-known " acid" sound can be produced with a TB-303 by playing a melody while changing the cutoff frequencyIn telecommunication, the term cutoff frequency ''f has the following meanings: 1. The frequency either above which or below which the output of a circuit, such as a line, amplifier, or filter, is reduced to the specified level of 3dB 70. 1% of the refere, resonanceThis article is about resonance in physics. For other uses, see Resonance (disambiguation). In physics, resonance is an increase in the oscillatory energy absorbed by a system when the frequency of the oscillations matches the system's natural frequency o, envelope modulationOn a subtractive synthesizer, envelope modulation is the amount that a modulation envelope effects a certain parameter ( filter cutoff, oscillator pitch etc. Most synthesizers include an ADSR envelope, meaning: Attack Decay Sustain (sometimes a sustain le, and accent controls. (The accent control modified the note volume, resonance, and envelope modulation.)

The unit had a single oscillator (set to either sawtooth waveThe sawtooth wave is a kind of basic waveform. It is named a sawtooth based on its resemblance to the teeth on the blade of a saw.

It also featured a 'simple' step-time method for entering note data into the 16-step programmable sequencer. This was notoriously difficult to use, and would often result in entering a different sequence than the one that had been intended - some users also take advantage of the quirky fact that when the batteries are removed for a certain period, patterns that are programmed in memory begin to vary in random ways - one of the factors that helped to create the randomish acid sound.

Roland's designer of the TB-303, Tadao KikumotoTadao Kikumoto is the designer of the Roland TB-303 and Roland TR-909. Currently, he is the Senior Managing Director at Roland Corporation., was also responsible for the well-known TR-909The TR-909 was a partially analog, partially sample-based drum machine built by Roland Corporation in 1984. Being the brainchild of Tadao Kikumoto, also the engineer behind the TB-303, it features a 16-step music sequencer and a drum kit that, at that tim ("Transistor Rhythm").
