The GCO-1 is a versatile quality compressor and expander plugin modeled after some of the best analog compressors. It has an open architecture with many means of adjustment, which ensures that almost any analog sound character can be obtained; from smooth and transparent, to warm and tubeish, or even pumping, if so preferred. It works well with all material for tracking, mixing and mastering.


  • High compression and expansion ratios.
  • Five envelope types including Opto-coupled.
  • Very short attack and release times.
  • Program dependency to avoid pumping.
  • Frequency dependent compression.
  • Adjustable knee and compression linearity.
  • Filters to eliminate low frequency disturbances.
  • Presets.
  • A|B comparisons.
  • Silent knobs.
  • 64 Bit Internal Processing.
  • Low CPU usage.
  • Supports sampling rates up to 192kHz.
  • Full VST automation.
  • No Latency.
  • Detailed Users Manual.

I'm a bit surprised that no-one has written a review for GCO-1 yet. This plugin is fantastic. It has got a lot of options but is really easy to use nonetheless. The sound is brilliant. It pumps when you want it to pump and it works almost inaudible when you want it to be neutral.
some people complained that GCO-1 is difficult to handle because it has got so many features - forget it!!! Most of the parameters you don't need to tweak at all if you don't want to - you start with a preset, set the treshold (all presets have set the threshold to zero db by default) and then you can finetune atack, release and ratio and choose the compression algo of which there are five different ones - all five sound great but very different from each other. If you feel like tweaking it a bit more then go for it as you have all the options you could wish for but you don't need to as it sounds fantastic anyway. The interface is very clean and easy to use. Also it doesn't have any internal latency and it doesn't use a lot of cpu. The docs are very good. I haven't needed any support yet but I know that Torben is very responsive and friendly.
What's missing? - Sidechain currently and also I'd wish it had an optional limiter at the output-stage but I can't think of anything else right now.
If you're looking for an absolutely professional sounding, highly flexible and easy to use compressor then I can't recommend GCO-1 highly enough. I use it for everything, be it vocals, guitars,drums/percussion, basses or mastering.Read more

I totally agree with everything the other reviewer said. It is now 2019 and I have not found a better VST compressor. Such a shame the company no longer exists.
