Using a Key Input for Side-
chain Processing
Bruno and Reso feature side-chain processing
capabilities. Side-chain processing allows you to
trigger certain parameters from a separate refer-
ence track or external audio source. The source
used for triggering is referred to as the key input.
You can use this capability to control the rate at
which Bruno performs sample switching or Reso
toggles its harmonics back and forth using the
dynamics of another signal (the key input).
Typically, a rhythm track such as a drum kit is
used to trigger these parameters and create
rhythmic timbral changes that match the
groove of the key input.
To use a key input for side-chain processing:
1 Click the Side-Chain Input Selector and
choose the input or bus with the audio you want
to use to trigger the plug-in.
2 Click the Key Input button (the button with
the key icon above it) to activate side-chain pro-
cessing.
3 To hear the audio source you have selected to
control side-chain input, click the Key Listen
button (the button below the Ear icon).
4 Begin playback. The plug-in uses the input or
bus that you chose as a side-chain input to trig-
ger the effect.
5 Adjust other parameters to create the desired
effect.
Bruno Parameters
Bruno uses time-slicing for tone generation, ex-
tracting timbres from the audio track during
playback and cross-fading them together at a
user-selectable rate.
This crossfading can create a rhythmic pulse in
the sound as the timbre changes. This makes
Bruno ideal for creating tonal effects with a con-
tinuously shifting timbre—similar to the wave
sequencing found on synthesizers such as the
PPG, Prophet VS, Korg Wavestation, and Wal-
dorf XT.
By carefully choosing the type of source audio,
the crossfade length, and the type of switching,
you can create unique and complex sound tex-
tures.
