PSP oldTimerME (Master Edition) is a compressor plugin that brings together two distinct versions designed to deliver a highly musical sound with detailed control. Rather than replicating specific hardware units, it draws inspiration from vintage compressor circuits, capturing their most appealing sonic qualities. This approach results in a plugin that offers warmth and character while maintaining flexibility suitable for various mixing scenarios.

The Master Edition stands out with advanced features, including the ability to selectively process left, right, mid, or side channels. Despite its sophisticated capabilities, the interface remains straightforward, allowing users to achieve professional results with minimal effort. The original PSP oldTimer focuses on simplicity and ease of use, making it accessible for both beginners and experienced producers who want a smooth, musical compression without extensive tweaking.

Both versions excel in delivering soft and smooth compression that enhances most audio sources. When pushed hard with high compression settings, the plugins introduce a subtle tube-like coloration on transients, adding a pleasing warmth and character to the sound. This makes PSP oldTimerME a great choice for users seeking compressors that blend transparent dynamics control with a touch of analog-style richness.
