The World’s First Matching and Component Based Studio Plug-Ins
Over the past decade, professional effects plug-ins have been about authentic analog emulation of original hardware, with either a black-box approach or circuit analysis and emulation. This gives musicians an easy-to-use user interface and faithful reproduction of analog tone in the digital domain.
Looking forward, the question is how we can create new tools to maximize the sound quality and usability with today’s new technology, with faster processors and memory, matching analysis, advanced nonlinear processing, and a cloud-based worldwide community. What can we do better, smarter, and more efficient?
Positive Grid teamed up the world’s brightest DSP engineers and component level modeling and matching authorities, working with the world’s leading producers, world-class engineers, and mixing & mastering gurus to develop some breakthrough technologies to bring software plug-ins to the next level.
Matching Compressor
The world’s first and unique compression matching works by measuring the dynamic response, pre and post filters, nonlinear transformer characteristics, and attack, release, and ratio curves to capture the nuanced sound of any compressor.
It accurately recreates the underlying architecture of the best compressors in the world, with the most intuitive user interface ever in a desktop plug-in. Audio engineers and musicians will now have virtual access to a wide assortment of the best compressors in the world, no longer limited by the traditional plugin architecture.

Tube Compressor
Models classic analog tube compressor at component level to add richness and fullness to the overall sound. You can instantly feel the difference by changing the input and output tubes, capacitors and transformers. Change the tubes and you can add a different harmonic characteristic and warmth to the sound, while changing capacitors and transformers colors the sound and brings up the high and low end.

Optical Compressor
It provides a careful emulation of the original optical compressor now at component level: you can even change capacitors to enrich the overall sound. We even modeled the light source and detector behavior, so you can fine tune and get the perfect attack and release characteristics by changing the light source, light source age, light source sensitivity, attack, and release knob.

FET Compressor
It captures the authentic sound and feel of the classic FET studio compressor thanks to its extremely accurate matching technology. At component level, it catches the peak very and applies compression with a very fast attack time, release time and look ahead function. It also filters out the low-end and high-end in its detector, so you can control the frequency range you want to trigger in the compression.
