The ADDAC 107 is a focused module – it's all about that squelchy, acid bass sound. If you're diving into techno, acid house, or industrial and want a dedicated, affordable voice to do it, this is a fantastic starting point. It’s not a general-purpose synth, but it nails its niche.

Frequently Asked Questions
It's not as smooth or creamy as a Moog, but it has a more aggressive, resonant character – leaning towards a Roland TB-303 vibe.
Tuning stability is decent for a VCO at this price point; occasional minor drifts are possible, easily corrected with calibration.
While optimized for acid sounds, you can get interesting results with creative modulation and filter sweeps, but it's not a versatile, general-purpose voice.
