The ACM500X1 channel EQ VST plug-in for Linux
Demo Limitations
Download and try for free. Every 60 seconds the plug-in will fade to silence momentarily. To remove this limitation you will need to buy an activation code.
To remove the demo limitations, open the plug-in in your host application and click the lock button at the top left of the plug-in to open the license entry dialogue. Type (or paste) your product activation code into the text box. You will then need to restart your host application to complete the process.
A natural sounding, versatile, analogue filter modelled EQ, economical with CPU and system resources.
Digital EQ no longer has to sound digital. The ACM500X1 VST plug-in for Linux emulates all the desirable qualities of a professional analogue channel equalizer, while the elegantly simple design makes adding texture and colour - or taming problem frequencies - both intuitive and instinctive.
Presented as a virtual 500-series module with a modern stylized user-interface, the ACM500X1 uses innovative analogue filter modelling to open up the frequency response and accurately replicate the more natural sound of analogue designs, without additional latency or high CPU demand.
More efficient use of CPU and system resources allows more plug-in instances in a typical audio workstation project.
  • Smooth controls with no 'zipper noise' when adjusting the plug-in settings.
  • High and low frequency shelving EQ.
  • Mid-range parametric EQ.
  • High-pass filter.
  • Physically modelled rotary control modes.
  • Resizable, modern user interface. As intuitive and easy to use as a traditional analogue console EQ.
  • Innovative processing models analogue filter behaviour - without additional latency or high CPU demand.
  • VST and VST3 plug-in for Linux.
