Only 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-SR 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-SR is sure to become one of your favorite synthesizers.
Pure Analog Signal Path
Great care has been taken in engineering the TD-3-SR, 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-SR 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.
Versatile VCF
The very heart of TD-3-SR'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 Oscillator
TD-3-SR'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 Sequencer & Arpeggiator
The 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. The onboard Arpeggiator features wide patterns you can build to provide a virtually-endless array of sound effects. Both the sequencer and arpeggiator in the TD-3-SR are fun, mesmerizing and totally addictive.
Controls & Connectivity
For those who want the numbers, TD-3-SR has 11 controls and 28 switches to give you direct and real-time access to all important parameters, all laid out in a highly-intuitive format that puts the joy back into your music creation. And you can expand TD-3-SR's tone-sculpting capabilities beyond your wildest dreams by utilizing the multi-I/O patchbay to connect external devices!
