SSL Native X-Echo is a vintage tape echo plug-in, inspired by the sound of definitive early tape delay hardware of the 1960s while introducing SSL's signature analogue saturation and warmth. Aside from sounding great from the get-go, it is complemented by numerous other practical and creative features, such as built-in de-essing, waveform visualisation, and a brand-new reverb design.


  • Inspired by early hardware delay units from the 1960s such as the Echoplex tape echo.

  • Combine tape-style analogue degradation with classic SSL-style distortion characteristics using the ‘Wow & Flutter’ and ‘Saturation’ controls.

  • Models classic characteristics of hardware tape echo devices, including the looping EQ, soft clipping, gentle tape hiss and self-oscillation when raising the feedback above 100%.

  • WOW AND FLUTTER emulates the effect of mechanical components like the capstan and pinchwheel, as well as the friction of the tape itself.

  • Use FREEZE and KILL to build risers and drops in recordings and live performances.

  • Bespoke one-knob DIFFUSION control, featuring a brand new reverb design.

  • Built-in DE-ESSER for controlling the sibilant frequencies that tape echoes often accentuate.

  • Designed to sound great from instantiation – even before you start tweaking it.

  • Unique interface and waveform visualisation for seeing how the tape heads interact.

  • Sync your delay to note values with a single click.

  • 4 switch-able tape heads for adding variation.

  • Cleverly stereoises mono => stereo signals using a phase-shifting technique.

  • Built on the SSL Plug-in Engine.

  • SSL’s cross-platform preset management and A/B-ing system.

  • Built-in UNDO/REDO support.

The AVA Spectral Compressor (AVA-SC) is a dynamics processor that allows you to apply compression selectively across 18 frequency bands. These compression bands can either be spread out across the full range of the spectrum, or focused on a specific frequency range for more precise control.

The Depth sliders below the graph control the maximum amount of gain reduction that can be applied to the corresponding frequency bands determined by the current Range setting. The Range can be set to focus on specific areas along the frequency spectrum (Low, Mid, High, etc.), or it can be set to Full Range mode to allow control over the entire spectrum. The Threshold sets the input signal level where the overall compression begins to take effect. Additional controls include compressor Knee and output Trim.


  • Threshold - The slider attached to the input meter on the left is the Threshold control. The Threshold sets the input signal level where the overall compression begins to take effect. The Threshold can be set anywhere between -60 and 0 dB.

  • Frequency Range - The Frequency Range section allows you to select the specific frequency range that gets processed by the compressor. The 18 compressor bands will be distributed across whatever range is selected. For example, with Mid selected, all 18 bands will be focused on the Mid-range, allowing for more precise control over the frequencies within that range.Depth - The Depth determines the maximum amount of Gain Reduction that can be applied within each slider’s control range. Possible Depth values range from -24 to 0 dB. Setting a Depth slider to 0 dB will prevent any attenuation from occurring within that slider’s control range.

  • Knee - The Knee value determines how far the input signal must exceed the threshold in a given band, to incur the full depth for that band. Possible Knee values range from 1 to 30. With a low Knee value (Hard Knee), the compression will activate more abruptly as the signal passes over the Threshold. A high Knee value (Soft Knee) will apply the gain reduction more gradually as the signal passes the threshold.

  • Output Trim - The Output Trim adjusts the level of the compressor’s output signal anywhere from -10 dB to +10 dB. It can be used to increase or decrease the output level as needed for gain compensation.

Gain Reduction Graph

The Gain Reduction Graph provides a visual representation of Gain Reduction across the frequency spectrum. The Reduction curve (red) is displayed above the Input curve (orange-yellow) indicating the amount of Gain Reduction applied and its location along the spectrum. The red line inside the Input curve indicates the level of the compressed signal relative to the input signal.
