Voxengo Tempo Delay User Guide
Introduction
Tempo Delay is a multi-feature stereo delay plugin for professional music production
applications. Tempo Delay is based on tempo, incorporating filter and tremolo
sections with separate controls for each stereo channel. Instead of a single “delay
length” control this plug-in features separate “delay”, “repetition period” and “delay
panning” controls which allow you to create an evenly sounding “ping-pong” stereo
echoes.

Compatibility
This audio plug-in can be loaded into any audio host application that conforms to the
AAX, AudioUnit, VST or VST3 plug-in specification.
This plug-in is compatible with Windows (32- and 64-bit Windows XP, Vista, 7, 8, 10
and later versions, if not announced otherwise) and macOS (10.8 and later versions,
if not announced otherwise, 64-bit Intel processor-based) computers (2.5 GHz dualcore or faster processor with at least 4 GB of system RAM required). A separate
binary distribution file is available for each target computer platform and audio plugin specification.

User Interface Elements
Note: Most interface elements (buttons, labels) located on the top of the user
interface and on the bottom are standard among all Voxengo plug-ins and do not
require much learning effort. For an in-depth description of these and other
standard user interface elements and features please refer to the “Voxengo Primary
User Guide”. Learned once it will allow you to feel comfortable with all pro audio
plug-ins from Voxengo.
Tempo
The “BPM” parameter specifies the base (overall) tempo of the delay plugin, in beats
per minute.
The “BPM Mult” parameter specifies the BPM value multiplier as numerator and
denominator.
The “Host BPM” switch enables synchronization of plugin’s BPM value with the
host’s master BPM value.
Delay & Gain
The “Delay” parameter specifies channel’s initial delay, in percent of the base tempo.
The “Rep Period” parameter specifies channel’s further repetition period, in percent
of the base tempo.
The “Feedback” parameter specifies repetition’s feedback amount, in decibel.
The “Panning” parameter specifies repetition’s stereo panning, in percent left-right.
The “Gain” parameter specifies channel’s overall loudness, in decibel.
Note that parameter values of the channels can be changed synchronously with the
right mouse button.
Tremolo
This section controls the sound of the tremolo effect.
The “Pre/Post” switch selects the position of the tremolo effect: the “Pre” position
applies the tremolo to the signal before the repetition is made, the “Post” position
applies the tremolo to channel’s overall output.
The “Period” parameter specifies tremolo’s period, in percent of the base tempo.
The “Depth” parameter specifies tremolo’s depth, in decibel.
Filter
This section controls the sound of the filter of the selected type. The filter is applied
before the repetition is made.

The “Freq” parameter specifies filter’s center/corner frequency in Hertz.
The “Q” parameter specifies filter’s quality: higher quality value produces a steeper
filter shape.
The “Drive” parameter specifies filter’s saturation amount (in percent).
Output
The “Wet Gain” parameter adjusts the loudness of the signal generated by the delay
module, in decibel.
The “Dry Gain” parameter adjusts the loudness of the original unprocessed signal, in
decibel.
The “Dry Mute” switch mutes the dry signal completely.
