Introduction

REVERSIDE is a sophisticated dual-engine reverb processor that combines Early Reflections (ER) and Late Reflections (LR) to create realistic acoustic spaces and creative effects. This manual explains all features and parameters in detail.

  • ER: Early Reflections - Initial sound reflections that provide spatial cues
  • LR: Late Reflections - Dense, diffuse reverberations that create ambience
  • UI: User Interface
Main Page

User Interface Overview

The interface is organized into four main panels (top to bottom):

  1. Top Panel: Main controls and navigation
  2. Reverb Tab Side Panel: Parameter category selection
  3. Main Parameter Panel: Detailed controls for selected tab
  4. Status Panel: System information, color edit etc

Controls and Parameters

Top Panel

[DEVPROAUDIO * REVERSIDE]

  • Clicking on above logo opens the About page with product information and licensing

Preset Management

Access the preset panel by clicking the preset name. It's got two sub-panels: side and main

Presets
  • [KEEP OPEN]: Keeps panel open while auditioning presets
  • [SAVE...]: Creates new preset in current bank/folder
  • [RESAVE]: Updates current preset with new settings

Preferences

No preferences at the moment

Bottom Bar

Click on a [=] button in right corner to open Bottom Bar Menu

Parameter Locks

Parameter locks allow you to prevent specific controls from being changed when switching presets. This is useful for maintaining consistent settings across different presets.

To toggle Parameter Lock mode:

  • Hold the Alt key while clicking on a control
  • Locked parameters will be visually indicated
  • Locked parameters will retain their values when loading new presets

Side Bar

Here you can switch between parameter edit pages. The 3x3 button grid is:

  • [ER ON/OFF][LR ON/OFF]: Engines
  • [ER DF ON/OFF][LR DF ON/OFF]: Diffusers
  • [ER EQ ON/OFF][LR EQ ON/OFF]: Output Equalizers

Reverb Engine Architecture

REVERSIDE uses a sophisticated dual-engine design:

Early Reflections (ER) Engine

  • Simulates initial sound reflections
  • Provides crucial spatial cues
  • Features integrated diffuser module

Late Reflections (LR) Engine

  • Creates dense, diffuse reverberations
  • Generates characteristic ambience
  • Includes independent diffuser

Key Features

  • Flexible ER/LR routing with precise mix control
  • Adjustable ER to LR feed
  • Independent stereo channel processing
  • Optional channel mixing via CROSS parameter

Both ER and LR engine also feature additional Input Diffuser which can be treated as a mini reverb. While ER's diffuser in built into ER engine, LR's can be used on its own independently.

Parameter Tabs

Main Tab

Pre-Delay Modes

  • ER PRE-DLY:
    • AUTO: Automatic setting based on direct path
    • ABS: Manual setting (Free or Host-synced)
    • REL: Relative to automatic value

Filter Controls

Hover over control to see transparent slider. Drag to control 3 bands. Press [EDIT] for full editor.

Modulation Controls

  • MOD DEPTH: Effect intensity (%)
  • MOD RATE: Speed (0-10 Hz)
  • MOD RAND: LFO randomness
  • MOD ON/OFF: Enable/disable
  • MOD MODE: Target selection

REFL (Reflections) Tab

SIZE Controls

  • Main Knob: Sets reference size in meters
  • Width (X): Relative room width
  • Depth (Y): Relative room depth
  • Height (Z): Relative room height

Surface Bounce Types

  • Walls: Room side surfaces
  • Floor: Bottom surface
  • Ceiling: Top surface
  • Random: General surfaces

Additional Parameters

  • [ER ON/OFF]: Enables/disables Early Reflections
  • [SHAPE]: Controls space irregularity (0-100%)
  • [DISTANCE]: Sets source-listener separation
  • [WALL ABS]: Controls wall absorption
  • [DECAY]: Adjusts reflection attenuation
  • [TM WARP]: Modifies delay timing spread
  • [ER NUM]: Sets number of reflections
  • [WIDTH]: Controls stereo image spread
  • [FILL-IN]: Simulates space contents
  • [CROSS]: Cross-mixes L/R channels
  • [GEOM PAN]: Use to position listener in XY plane
  • [MIC SEP]: Controls L/R position distance
  • [DST/SRC Z POS]: Sets relative Z position
Reflections

REV (Reverb) Tab

DENSITY Control

Configuration recommendations:

  • 2,3,4 (high): Fast transients
  • 2,3 (low): Vocal enhancement
  • 1: Sustained sounds

The higher config number correspond to denser tail

Key Parameters

  • [DIFFUSE]: Controls the diffusion
  • [WIDTH]: Stereo field control [STD/WIDE] button. switches normal and wide stereo modes
  • [CROSS]: Channel mixing
  • [CONTOUR]: Envelope shape control
  • [CURVE]: Build-up control
  • [REV TIME]: RT60 decay time
  • [REV SPREAD]: Control a spread of delays inside reverb, for natural sounding use 30% value, use bigger values if you want to increase a perceivable acoustic space size
  • [PD MIX/SCALE]: Envelopment control
  • [CONFIG]: BASE/STD/...
  • Panning controls: Density, RevTime(RT Pan), Env CV/DCY: Allow to scale down L (negative value) or R (positive value) channel's param value. For example, if RevTime = 2s, and RT_Pan = -100, the Left channel's rev time will be around 0.2s, and Right's remain 2s. the actual amount of scaling down depends on control.

Envelope Modes

  • [STD ENV]: Natural exponential decay
  • [FAT ENV]: Extended body

Note that envelop display's Y axis is in dB thus an exponentially decaying curve is shown as line.

Mix

Tips and Best Practices

  • Start with factory presets
  • Adjust SIZE first
  • Fine-tune with SHAPE and DISTANCE

Troubleshooting

Common issues and solutions:

  • CPU spikes: Lower DENSITY and ER NUM
  • Metallic sound: Reduce DIFFUSE or adjust MOD
  • Unclear image: Check WIDTH and CROSS settings
  • Muddy bass: Adjust DCY low band or EQ
  • Harsh highs: Use MAT filter or adjust EQ
