24-September-2025 : ACM76SA FET Compressor Plug-In Released
Inspired by one of the best-known vintage FET compressors, the ACM76SA offers a wide range of settings from mild 4:1 compression, with a soft-knee compression curve, to more obvious limiting at 20:1 while the classic 'All Buttons' or 'British' mode can be used for additional rich overdriven texture.
A switchable side-chain highpass filter adapts the plug-in for contemporary bass-heavy mixes, without over compression. The ACM76SA emulates all the desirable qualities of a vintage FET compressor, taming dynamics with fast attack and program dependent release, while adding its own unique harmonic colour.
 
Available as VST2, VST3 and CLAP format plug-ins for Windows and Linux together with AAX for Windows. Demos are available to download for free.

14-March-2025 : ACM-Series Plugins Updated to Version 3.3.0
The ACM-Series plug-ins V3.3.0 for Windows and Linux are now available. This update provides some minor bug fixes, improved integration with Reaper's 'MIDI Learn' feature, and the addition of a preferences panel for selecting the rotary control mode.
 
Preferences Clicking the preferences button opens the plug-in preferences panel to configure the control mode. The control mode determines the way in which the rotary controls respond to mouse movement. This may also be configured via the host application preferences where applicable.
  • Circular. In this mode, clicking on a control will move it immediately to the mouse pointer’s angular position. To adjust the control, drag the mouse pointer in a circle or an arc. Increase the arc radius for fine control.
  • Relative Circular (Default). This is the default mode. Similar to circular mode, however moving the mouse will adjust the control relative to its current setting.
  • Linear. In this mode, the control responds to vertical mouse movement. Drag up to increase the value, turning the control clockwise, or down to decrease the value, turning the control anticlockwise. Hold down [ Shift ] for fine control.
In all modes, double clicking the centre of a control will return it to its default position.
 
The plug-ins offer a comprehensive collection of analogue modelled processing. De-cramped, analogue modelled filters ensure the correct equivalent response - even at low sample rates - without requiring CPU intensive oversampling or additional latency, while smoothed interpolated controls ensure glitch free parameter adjustment with no 'zipper noise' - features which are not always present on some other plug-ins. This is a free update for existing users. Download the latest release and free demos at: www.acmt.co.uk
28-May-2024 : ACM SA-Series Plugins Updated to Version 3.2.0
The ACM SA-Series plug-ins V3.2.0 for Windows and Linux are now available. This update includes some GUI improvements and minor bug fixes.
 
The ACM-SA series offers a collection of outstanding analogue modelled mastering plug-ins for Windows and Linux PCs, transforming a digital audio workstation into a versatile virtual analogue mixing and mastering environment.
 
The ACM-SA series plug-ins plug-ins feature de-cramped, analogue modelled filters to ensure the correct equivalent response, even at low sample rates, without the need for CPU intensive oversampling or extra latency. In addition, smoothed interpolated controls ensure glitch free parameter adjustment with no 'zipper noise' - features which are not always found on other plug-ins.

01-March-2024 : ACM-Series Plugins Now Available for Windows
The ACM-SA and 500X series plug-ins are now available in VST, VST3, and CLAP format for Windows and Linux PCs. For anyone thinking of switching to Linux, the plug-ins offer a comprehensive collection of analogue modelled processing, or for those not quite ready to make the change, Windows compatible versions now provide cross-platform solution for use with existing digital audio workstations.
 
The plug-ins feature de-cramped, analogue modelled filters to ensure the correct equivalent response - even at low sample rates - without the need for CPU intensive oversampling or extra latency. In addition, smoothed interpolated controls ensure glitch free parameter adjustment with no 'zipper noise' - features which are not always present on some other plug-ins.
 
Windows versions are provided as a free update for existing users, available to download from the product download pages.

04-April-2023 : ACM210X1 Graphical EQ Plug-In Updated to V3.1.4
The ACM210X1 plug-in for Linux provides up to ten EQ bands, using improved de-cramped analogue modelled filters which accurately replicate the equivalent analogue response, without requiring oversampling, or additional latency.
 

Stereo Placement - New In V3.1.4

ACM210X1 context info pop-up Starting with version 3.1.4, the context info pop-up associated with the active EQ band is now split into two parts. The right-hand side shows information about the frequency, gain and bandwidth settings for the selected band, while the left-hand side contains a toolbar for selecting stereo placement and solo options.
Individual EQ bands can now be assigned to left, right or stereo channels, while the solo option auditions or solos the frequency range associated with the selected band.
 
This is a free update for existing users, the latest version of the plug-in is available to download from the ACM210X1 product page.
03-Jan-2023 : ACM520X1 Stereo Bus Compressor Plug-In Released
Inspired by one of the best-known console bus compressors, the ACM520X1 offers a wide range of settings from gentle 2:1 compression, often regarded as the essential 'glue' of a cohesive mix, to more obvious punch at higher compression ratios. In addition, a switchable side-chain highpass filter makes it ideal for bass-heavy mixes, without over compression. The ACM520X1 plug-in for Linux emulates all the desirable qualities of a professional analogue console bus compressor, taming dynamics without restricting the natural character of a mix or performance.
 
Available as VST2, VST3, CLAP and JACK format plug-ins for Linux. Demos are available to download for free.
