29-December-2025 : ACM-1A Vintage Program EQ Released
Inspired by vintage Pultec style EQs, renowned for their ability to simultaneously boost and cut the low frequencies using separate controls - creating powerful, tight bass boost with focus and detail. The ACM-1A combines high performance processing with an intuitive stylized user interface. Perfect for adding that big studio sound to in-the-box mixes.
ACM-1A HF Boost and Attenuate Front Panel Controls
Building upon the popular ACM-2SA plug-in, the ACM-1A features an updated DSP model with improved HF Boost and Attenuate control interaction, together with a modified transformer saturation model which extends the low-end for greater bass response compared to the original plug-in. This is a free addition for existing users of the ACM-2SA, the ACM-1A is available to download for Windows and Linux PCs at: www.acmt.co.uk
 
03-November-2025 : ACM76SA FET Compressor Updated to V3.4.0
Inspired by one of the best-known vintage FET compressors, ACM76SA V3.4.0 provides the following improvements and bug fixes:
  • Bug fix. This update addresses an issue when opening the preferences or license entry panel on portrait oriented screens.
  • Bug fix. Factory preset management modified to prevent issues which could occur when reloading a session in Ardour / Mixbus.
  • Feature update. The 'OFF' text below the attack control will now change colour when gain reduction is disabled. Holding [Shift] and double-clicking the attack control enables or disables the gain reduction, allowing the harmonic colouration provided by the transformer and VCA emulation to remain, while inhibiting the compressor action. Gain reduction can also be inhibited by configuring the ratio selection buttons for 'All Buttons Off'
This is a free update for existing users, the ACM76SA is available to download for Windows and Linux PCs at: www.acmt.co.uk
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.
