Roland TB-3 AIRA Series Touch Bassline 〈Product Contents〉Main unit, power adapter. □Operation has been confirmed. It works without any problems. 【Reference Explanation】 The TB-303, released in 1981, is still loved as an indispensable bass synthesizer in dance music. In developing the TB-3, the circuit configuration of the TB-303 was carefully analyzed at the component level, thoroughly examining the operation and behavior of each circuit. ACB technology perfectly reproduces the oscillator consisting of sawtooth and square waves, the -18dB/oct ladder low-pass filter, and even the filter's cutoff and resonance behavior. The TB-3 includes not only the classic TB sound but also extreme sounds processed with effects such as distortion and delay. Sound characters that were impossible with the original have been added. 〈Specifications〉 Number of Tones Preset Patches: 134 Sequencer User Patterns: 64 Maximum Memory Steps: 32 (per pattern) Scatter Presets: 8 Controllers: Touchpad, Cutoff, Resonance, Accent, Effects ・Connections PHONES Jack: Stereo standard type OUT (L/MONO, R) Jacks: Standard type MIDI (IN, OUT) Terminals USB Terminal: USB Type B (Audio/MIDI compatible) Power: AC adapter, obtained from USB terminal (USB bus power) Accessories: Power adapter External Dimensions: W240 x D173 x H57mm Weight: 820g
