For optimum effect, set the Damping Amount to
a middle value, then set Damping Velocity ac-
cordingly for the desired effect.
The resonator adds harmonic overtones to the
source audio signal that are integer multiples of
the fundamental frequency of the signal. The
Harmonics control selects between all of these
harmonics, or just the odd-numbered intervals.
Your choice will affect the timbre of the sound.
All
Adds all of the harmonic overtones generated by
the resonator. In synthesizer parlance, this pro-
duces a somewhat buzzier, sawtooth wave-like
timbre.
Odd
Adds only the odd-numbered harmonic over-
tones generated by the resonator. In synthesizer
parlance, this produces a somewhat more hol-
low, square wave-like timbre.
Reso Toggle Controls
Reso can automatically toggle between the All
and Odd harmonics settings, producing a rhyth-
mic pulse in the timbre.
Harmonic toggling can be controlled either by
triggering (using the dynamics of the source au-
dio itself, or those of an external key input) or
by MIDI Beat Clock.
External Key
Toggles the harmonics from a separate reference
track or an external audio source. The source
used for toggling is referred to as the key input
and is selected using the Side-chain Input pop-
up. You can assign either an audio input channel
or a TDM bus channel.
Typically, a drum track is used as a key input so
that toggling occurs according to a definite
rhythmic pattern.
Key Listen
When enabled, monitors the source of the key
input. It is useful to do this to fine tune Reso’s
settings to the key input.
Threshold
Sets the level in decibels above which toggling
occurs. When the audio input level rises above
the Threshold level, Reso will toggle its harmon-
ics setting. The range of this control is from a
low of –48 dB (maximum toggling) to a high of
0.0 dB (no toggling). If no key input is used, the
dynamics of the source audio will trigger tog-
gling. If a key input is used, the dynamics of the
key input signal will trigger toggling. Thresh-
old-based switching can be used at the same
time as Key Input-based switching.
MIDI Clock
Triggers toggling in sync with a MIDI Beat Clock
signal. This creates a very regular, highly rhyth-
mic wave sequencing effect that is ideal for ses-
sions arranged around MIDI beat clock. This
control can be set to quarter, eighth, or six-
teenth notes, or dotted triplet values of the
same.
Damping Velocity only has an effect when
you play Reso with a velocity-sensitive
MIDI keyboard controller.
