Introducing The AudioScape MK-609 Plugin

The original 1969 diode-bridge compressor became one of the defining sounds in large-format console mixing. AudioScape Engineering redesigned it with modern improvements, and we built the plugin together from their updated circuit.

Three attack modes (including a super-fast setting they added), five ratios, and a sidechain high-pass filter at 50Hz and 100Hz give you more flexibility than the original ever had while keeping the same compression character.

Limiter after the compressor

Limiter after the compressor

The limiter section sits after the compressor in the signal flow and handles the final stage of dynamics control.

Use the compressor on its own for glue, the limiter on its own for peak control, or run both together for a complete dynamics chain in one plugin. It smooths drum transients, tightens bass guitar, and controls vocal stacks without making the source feel smaller.

From transparent to aggressive in one knob

At low gain reduction the MK-609 is clean and punchy. Push it harder and the compression starts to move with the music, adding a lively pump that makes drums and mix buses feel alive.

The sidechain HPF keeps low-end energy out of the detector so kick drums and bass don't trigger unwanted gain reduction on the rest of the mix.

Stereo, dual mono, or mid/side

Stereo, dual mono, or mid/side

Run both channels linked for standard bus processing, unlinked for independent left/right control, or in mid/side mode to compress the center and sides of a stereo image separately.

Every Kiive plugin includes the top bar with input/output gain, oversampling up to 4x, a mix knob for parallel blending, harmonic distortion control, and stereo width.
