This emulation delivers all the features from the original unit, along with some extras such as an external sidechain input, a 3 band filter and mix knob for quick parallel compression.
Borrowing all core functionalities from the original unit, it adds the ability to fine-tune almost every parameter, from the envelope timing and saturation level to the sidechain high-pass filter and dry/wet mix levels.
ADHD’s Leveling tool allows much more settings than the original LA-2A unit, such as variable ratios, adjustable attack/release times, an high-pass sidechain filter, a drive control and a dry/wet knob.
