The ML4000 Mastering Limiter HD v7 Black Friday deal is 44% off, $99, with the offer ending Nov 23, 2026, on McDSP's high-resolution limiter and multi-band dynamics processor for AAX DSP users.
This is the HD version of the ML4000. A Native version also exists, so AAX DSP is the thing to confirm before you buy.
McDSP built it for music, mastering, post and live sound.
The ML4000 is two plugins in one package: the ML1 mastering limiter and the ML4 multi-band dynamics processor.
The ML4 feeds into the same limiter algorithm the ML1 uses, so the multi-band stage and the final limiting sit in one signal path.
The ML1 is a brick wall look-ahead limiter. It runs several stages of limiting, which McDSP says gives it better peak detection.
Two controls shape its behaviour: Knee and Mode. The maker says they let the ML1 respond anywhere from transparent to aggressive, depending on the material.
The ML4 splits the signal into 4 bands. Each band has a Gate, an Expander (upwards or downwards) and a Compressor.
You can set each band's three processors independently or link them together. The dynamic curves for Gate, Expander and Compressor show at the same time in every band.
Steep 24 dB/Oct crossover filters keep signal from leaking into neighbouring bands. On the crossover page you drag the crossover frequencies graphically while a real-time display shows the frequency response of the input, the output or the total dynamics effect.
Setting the final level is handled by an output ceiling control, large meters and text readouts of the meter levels.
McDSP HD plugins support AAX DSP, AAX Native, AU and VST3. As of v7.0, the older VST format is no longer supported.
On Mac you need macOS 10.13 or higher, 64-bit only. On Windows the list is Windows 7, 8 and 10, also 64-bit only.
McDSP lists Pro Tools, Logic Pro, Cubase, Nuendo, Ableton Live, LUNA, Reaper, Sonar and Studio One as compatible, along with other DAWs that support AAX, AU or VST3. HD plugins also support VENUE S6L systems through a separate VENUE installer.
Activation runs through an iLok2 or iLok3 USB Smart Key, or a free iLok License Manager account with an iLok Cloud session. Each license or subscription carries two activations.
