Signal Flow
This chapter describes the signal path through Toraverb 2. It explains the basic components of the unit and its control parameters.
Basic modules
Internally Toraverb 2 consists of a few basic components. These correspond to the secons on the graphical user interface.
Pre-delay
Controls the delay between Dry and Reverberated signals

SIGNAL FLOW BASIC MODULES
By default Pre-delay is expressed in milliseconds and controlled in a range of 0to 500 [ms] (when Sync mode is disabled). The value can be
adjusted by dragging the mouse pointer up or down above the digits represenng the consecuve decimal posions on the display.
Sync. toggle buon:
Sync. buon
This acvates / deacvates the synchronizaon of the Pre-delay with the host applicaon tempo. When enabled, the delay is represented
as a Rhythmic value (in tempo-dependent units) consisng of Note value and Rhythmic modier. It should be noted that when this mode is
acve the Pre-delay value is controlled in a slightly dierent manner and the look of the Pre-delay display changes.

Note values
The Pre-delay’s Note value can be adjusted by dragging the mouse pointer up or down while selecng it.
Pre-delay’s Note value
We can choose one of following values; 1 Bar, 1/2, 1/4, 1/8, 1/16, 1/32 and 1/64.
Rhythmic modiers
Clicking one of available Rhythmic modiers, selects it;
Pre-delay’s Rhythmic modier
There are 3 values to choose from:
• Full – Eecve delay value is equal to set Note value.
• Tri - Eecve delay value is equal to 2/3rds the duraon of set Note value.
• Dot - Eecve delay value is equal to 3/2nds the duraon of set Note value.

Early / Late reecons secon
This secon controls the Early and Late reecons of reverb.

Switching between Early and Late tabs gives an access to parameters controlling Early and Late reecons respecvely.

Early reecons tab
This tab controls the early reecons of the reverb.
Secon controlling Early reecons’ tail
The following parameters can be selected:
• Size - Size of the room.
• Bass cut - Controls the properes of the reecng surface with respect to bass frequencies. Bass frequencies are cut below the value
selected. The range is from 0Hz to 22kHz.
• Crosstalk – Between the le and right channel delay lines
• Aenuaon - This parameter changes the characterisc of the reecng surface - it’s damping properes.
• Diusion – – Is the reecng surface’s ability to spread the echoes out. If this parameter is set to Sharp, the reecng surface is
perfectly at and does not distort reected waves. If this value is set to Smooth, the reecng surface distorts the waves and spreads
them out into dierent direcons.

Late reecons tab
This tab controls the Late reecons of the reverb.
Secon controlling Late reecons’ tail
The following parameters can be selected:
• Size - Size of the room.
• Bass cut - controls the properes of the reecng surface with respect to bass frequencies. Bass frequencies are cut below the value
selected. The range is from 0Hz to 22kHz.
• Feedback – Controls how much of wave energy is consumed every reecon. The less value the more energy consumes every
reecon, that means the feedback is weaker then.
• Aenuaon - This parameter changes the characterisc of the reecng surface - it’s damping properes.
• Diusion – Is the reecng surface’s ability to spread the echos out. If this parameter is set to Sharp, the reecng surface is perfect-
ly at and does not distort reected waves. If this value is set to Smooth, the reecng surface distorts the waves and spreads them
out into dierent direcons.

Parameters to the right on the tab, labeled in orange, control the single-band parametric EQ which alter the Late Reecons.

The Early me and Late me display shows the decay mes of Early and Late reecons respecvely. This is purely for informaonal purpose.

• FX - Crossfade between Dry and reverberated Wet signal.
• Padlock
allows the Dry/Wet balance to be locked so that it does not change when loading presets.
• FX Curve – Transion characteriscs between Dry and Wet for FX knob
• Ducking – Controls the compressor which suppresses the Wet signal proporonally to the level of the Dry signal. This knob controls
the strength of the eect.
• A./Rel. – Adjusts the Ducking Aack and Release mes starng from
• 2ms of aack and 50ms of release for minimum value up to
• 16ms of aack and 400ms of release for maximum value.

Preset Storage
Presets, both those from the Factory content, and User ones, are stored as les in proper locaons on a disc. Each me the plug-in
instance is loaded to the project, these locaons are scanned and presets found there are consolidated into one linear structure (list)
in the Preset Browser.
Browsing Presets
Presets Conguraon and Management secon enables quick navigaon and browsing the presets structure:
Presets Conguraon and Management Secon
• PRESET NAME – Displays the name of the currently loaded preset.
• PREV / NEXT – Buons that allow for linear browsing of presets list (depending on currently set lters – see secons below).
• INIT – Win ( Ctrl + PREV ), Mac ( Cmd + PREV ) – Restores inial sengs of plug-in parameters.
• RELOAD –Win ( Ctrl + NEXT ),Mac ( Cmd + NEXT ) – Reloads a current preset.

• SAVE – Win (Ctrl + BROWSE ), Mac ( Cmd + BROWSE ) – Saves current parameters as a new preset or allows for overwring

• BROWSE – Expands the Preset Browser panel at the boom of GUI secon.
The Preset Browser looks as follows:

One can see three main secons:
• Content – Sources from which presets can be read.
• Filters – Conguraon of presets Filters (non-acve by default).
• Results – List of presets from resources that meet criteria set by Filters.

Resources
In this secon you can choose a resource/resources in which you want to browse presets. There are two resources to choose from:
• Factory – Delivered together with the plug-in, cannot be modied (read-only).
• User – Created by the user during using the plug-in and can be freely modied, shared with other users etc.
Choosing any of them will cause narrowing the results to the presets from one resource.
Preset Filters
The plug-in enables classicaon of presets with the use of Categories and Tags system, whose aim is to facilitate the process of browsing
the content by ltering.
