SSi Pro Compressor: VST2 Compressor Plugin by Minimal System Group Free Download

The compressor is built on what Minimal System Group calls a high-end sound engine. The analogue-modeled tube gain stage is the part of the design that colors the signal, adding harmonic character alongside the gain reduction.

Use the gain control to set output level after compression, and the knee control to decide how the compression engages around the threshold. A softer knee tends to make the transition less noticeable, while a harder setting makes the compressor react more abruptly.

The full control set gives you a lot of room to work. Attack and release set how quickly the compressor responds and recovers. Threshold and ratio define how much the signal is reduced once it crosses the set level. Range limits the maximum amount of gain reduction, and hold keeps the compressor engaged for a set time. An RMS option is included as well.

The presets give you starting points for common uses, so you can open the plugin, choose a preset and refine it from there. The interface is laid out to keep the main controls in view, and because CPU use is low, you can place the compressor on many tracks without slowing the session.
