The Maselec mla-4 Black Friday deal from Relab Development brings the triband compressor/expander plugin to $129, which is 35% off, with the offer ending Nov 30, 2026.
The MLA-4 is a software version of the hardware Maselec unit. The maker calls it the first and only officially endorsed software recreation, built in direct collaboration with Leif Mases.
It is made for mixing, mastering and stem processing. The maker describes the dynamic shaping as natural and musical, with precise control across three bands.
It works as both compressor and expander across three bands. Relab says it suits a final master, a mix bus, or a crushed stem that needs its dynamics restored.
Software also allows workflow features the hardware never had. Those are covered in the list below.
The monitoring tools exist so you can adjust by ear on what you hear, not on guesses.
