5:2 Master tuning controls
The Pitch and Fine controls allow you to tune the master oscillator bank.
Due to Amber’s paraphonic architecture, these controls adjust the pitch of all paraphonic notes within a single
voice simultaneously.
You will mainly need to use these controls when using multiple Amber voices – try setting some modulation
on the
Fine control from a Voice or Unison source in order to detune each voice.
You could also use the Drift source to modulate the pitch when using a single voice, in order to simulate a
synth with unstable, drifting oscillators.

Level controls: 8’, 4’ & Nse
The Synth section features level controls for the 8’ and 4’
octaves, and for a gaussian white noise generator ( Nse).
When using the AmberFX plugin (MIDI-controlled audio effect
plugin version), the external audio input appears in place of the
Nse source.
Inv (invert)
The Inv button inverts the phase of the Synth section in relation
to the Ensemble section. This can result in interesting phase-
cancellation effects when both sections are in use.
Paraphonic ADSR envelopes and VCAs
Each note in the Synth section possesses its own dedicated
ADSR envelope to control its amplitude over time (the envelopes
are internally connected to VCAs for each note). The shape of all
these envelopes is dictated by the Synth Envelope.
Vel (Velocity)
The Vel control sets the velocity sensitivity for the Synth section’s VCAs. At the minimum setting, there is no modulation of
amplitude by velocity.
LP & HP (paraphonic 1-pole tone filters)
The tone of each paraphonic note is adjusted by a 1-pole filter stage featuring high-pass and low-pass filters. Use the LP
and HP controls to adjust the cutoff frequencies of these filters.
These filters are keytracked (directly modulated by keyboard pitch) relative to the cutoff frequencies, with maximum depth.
This direct modulation cannot be adjusted.
Filter stage (polyphonic multimode resonant filter)
All the individual paraphonic Synth section notes are summed before being passed through the multimode resonant filter
stage.
This filter stage is polyphonic – monophonic for each voice.
Power
The Power button enables or disables the filter. When disabled, incoming audio passes through the filter stage unaffected.
Cutoff & Res (Resonance)
The Cutoff and Res parameters control the cutoff frequency and resonance of the filter stage,
Mode
The resonant filter can be used in any of the following modes:
• Low-Pass 2-pole or 4-pole
• High-Pass 2-pole or 4-pole
• Band-Pass 2-pole or 4-pole
• Peak 4-pole
• Notch 4-pole
