ADDAC System Releases Acid Source

ADDAC System has announced its latest Eurorack module, ADDAC107 Acid Source. They say that it is a compact synth voice incorporating full VCO, VCF and VCA functionality, that 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.

A spokesperson told us, "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. They say that the result is a highly flexible, fully featured synth voice that is timbre-rich and sonically capable.

Pricing and Availability:

The ADDAC107 Acid Source module is available now for 210€, and will soon be available as a DIY kit as well.
