ADDAC System ADDAC107 Acid Source

The ADDAC Acid Source, a compact synth voice incorporating full VCO, VCF and VCA functionality, forays deep into acid sonic territory with classic ‘squelchy’ sounds all of which may be shaped using its built-in low-pass, band-pass and high-pass filters. Whether being used for a plucky bass line, a squelchy lead synth line or scratchy percussion, ADDAC107 delivers epic acid sounds in spades. ADDAC System engineers originally designed the module as a complex drum source, but along the way, noticed its strengths as a synth voice and embraced this change in course as a happy accident. The result is a highly flexible, fully featured synth voice that is timbre-rich and sonically capable.

VCO sectionThe ADDAC107’s VCO features Frequency and Fine Tune knobs, as well as a dedicated CV Input and Attenuator knob that is tunable over four octaves. The VCO waveform output is achieved by selecting either the Triangle or Saw option, via the faceplate switch.
