TD-3-BKOnly produced from 1981 to 1984, the Roland TB-303 was a tremendous commercial flop as a replacement for the bass guitar, however it soon found its place as one of the most-loved synthesizers for what became known as Electronic Dance Music (EDM). An ultra-affordable and faithful homage to the iconic synthesizer that spawned house music, plus an all-new Distortion circuit, the TD-3-BK lets you conjure up virtually any sound with incredible finesse and ease. With its pure analog signal path, 16-step Sequencer and authentic VCO, VCF and VCA filters, the TD-3-BK is sure to become one of your favorite synthesizers.Pure Analog Signal PathGreat care has been taken in engineering the TD-3-BK, including the true to the original VCO, VCF and VCA designs and pure analog circuitry with matched transistors. This highly-focused attention to detail is what gives TD-3-BK its ultra-flexible sound shaping capability, which covers everything from super-fat bass and lead tones to stunning effects - all the way out to the otherworldly sounds of your imagination.Rock Right out-of-the Box!Your TD-3-BK comes ready to rock, thanks to its default signal routing that doesn't require lifting a single patch cable to instantly create amazing sounds. The highly-intuitive layout lets you easily tap into the inspired sounds of 1980s and '90s progressive rock, wave, EDM and synth-pop music tracks that made rock and roll history - or to design incredibly fat and original sounds that will make you a legend in your own right!Versatile VCFThe very heart of TD-3-BK's sound is its versatile 24 dB/octave filter, which lets you freely experiment with the low-pass Cutoff frequency and Resonance settings to dial in the perfect sound.Vintage OscillatorTD-3-BK's authentic Voltage Controlled Oscillator (VCO) with transistor wave-shaping circuitry is ultra-easy to use and provides your choice of reverse-sawtooth or pulse waveforms for the ultimate in sound creation.Onboard SequencerThe onboard sequencer with 7 tracks allows you to program up to 16 steps of notes and rests and save them as a Pattern. You can record, save and recall up to 250 patterns, all of which can be stored in the 4 Groups. Your sequences can be played either in Keyboard mode, where you create and store the pattern, or Step mode which allows you to interact while composing a pattern.Kick it Into Distortion!We saved one of the most exciting features for the last stage in the all-analog signal path - Distortion! When you want to add even more power to your performance, just flip the Distortion On/Off switch and dial in the perfect amount of Drive to push the "envelope" to the max. The crowd won't know what hit 'em!16-Note Poly Chain ReadyWhile it is a monophonic instrument (one note at a time), TD-3-BK's 16-note Poly Chain function lets you combine multiple synthesizers for up to 16-voice polyphony - plus provides vastly improved reliability and stability over its 1970s and '80s predecessors.Controls & ConnectivityWe just can't help ourselves - like you, we're gear-heads, too.
