Roland SDX330 3d Chorus (Used)

The SDX330 is housed in the customary Roland 1U matt black rack chassis, with familiar two-line backlit LCD window, plus program number display. The LCD shows the program name at all times, in Play mode, but the user is given the option to have programs recalled with a specific parameter also visible. In Edit mode, the LCD shows up to three parameter and value combinations simultaneously. As there will invariably be more than three parameters making up a preset, the visible ones can be horizontally scrolled, using the alpha dial or +/- keys. The three function keys can then be used to select one of the visible parameters for editing -- once this is done, the alpha dial and +/- keys will now act on the value. There are about as many different operating systems in this world as there are multi-effects units, and each has its strong and weak points. Roland's is about as simple and obvious as they come, and certainly one of the fastest to learn.


The 100 factory programs are derived from 16 algorithms, with Parametric EQ and MIDI real-time control assignments common to all.

• STEREO CHORUS: a true stereo input and output chorus, with variable phase between left and right channels.
• STEREO 3D CHORUS: true stereo chorus, with 3D positioning added.
• 3D PANNER: Dynamic 3D panning effects, with control of speed, direction, and start point.
• SPACE CHORUS: a wide, spatial chorus, very accurately replicating Roland's own SDD320 Dimension D unit.
• 2-BAND CHORUS: true stereo chorus with two-way band-splitting for separate chorusing of different frequency zones. Crossover point variable from 400Hz-4kHz.
• 3-BAND CHORUS: true stereo chorus, with three-way split. Crossover points, 100Hz-1kHz, 800Hz-8kHz.
• 4-BAND CHORUS: mono input, stereo output chorus, with four-way frequency division. Crossover points, 100Hz-1kHz, 400Hz-4kHz, 800Hz-8kHz.
• STEREO 8-PHASE CHORUS: a complex true stereo chorus, with independent parameters for each of the eight 'voices', including LFO phase and polarity.
• 16-PHASE CHORUS: a mono (in and out) chorus, with preset Modes, rather than independent voice parameter control.
• DETUNE CHORUS: a true stereo, non-cyclic chorus effect, with six high resolution pitch shifters in parallel.
• ENSEMBLE: stereo/mono chorus using LFOs of differing speeds. Uses Preset modes, rather than user-variable parameters.
• WAVE CHORUS: true stereo chorus, with choice of six LFO waveforms.
• VINTAGE CHORUS: Roland CE2-type analogue chorus simulation.
• STEREO FLANGER: true stereo flanger, with choice of LFO waveform.
• ROTARY: uncannily accurate simulation of rotary cabinet, complete with overdrive stage, and offset speed-up and slow-down rates for top and bottom rotors. Great!
• AMBIENCE CHORUS: chorus with simulated stereo ambience, adding greater spaciousness to the effect.
