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

User Interface Overview
The interface is organized into four main panels (top to bottom):
- Top Panel: Main controls and navigation
- Reverb Tab Side Panel: Parameter category selection
- Main Parameter Panel: Detailed controls for selected tab
- 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

- [KEEP OPEN]: Keeps panel open while auditioning presets

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 pathABS
: 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

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.

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
