REFERENCE
GUIDE
RESONATOR
TUNE
Changes the pitch of the resonator bank by
altering the sample rate of the DSP over a
4 octave range. Range/spacing of the
resonators is determined by MODE.
DAMPING
High frequency damping of the resonator.
Turn clockwise to increase brightness,
with metallic artifacts at max. Highly
interactive w/ DECAY.
DECAY
Overall resonator sustain. At higher
settings, adds an analog feedback loop to
create sustaining, metallic drones.
MODE
Selects the interval spacing between
strings in the resonator bank as follows:
Single note. Straightforward, with
additional strings forming overtones.
Stacked neutral 3rd. Has a dreamy
quality thanks to its microtonal nature.
Stacked 5th. Deep, expansive, and
sustaining, like a giant piano floating in
the astral plane.
Chromatic. Twelve strings,
packed a semitone apart. Uses a lower
fidelity string model to maximize
density, while imparting a slight digital
haziness.
Long press MODE to shiſt up an octave.
This also mellows out higher overtones.
I/O I/O
Audio: low noise, high
headroom buffered dry path
with selectable regular or
trails bypass.

PRESETS
each
To save, hold until the first
LED blinks. Then scroll to a
slot and long press to confirm.
To recall, press Preset to
scroll through slots 1-3.
Up to 16 slots available via
MIDI PC messages.
CTRL: use 0-5V CV, an
expression pedal, or tip active
MIDI (via a MIDI box). Auto-
configures based on its input.
AUX
Use the button to determine
footswitch behavior.
MORPH mode intelligently and
expressively ramps between
two control states.
PRESET mode scrolls through
the first 3 preset slots.
Power: 9VDC, <200mA.
Protected from over-voltage
and reverse polarity
conditions.
ANALOG
MIX
Sets the relative balance of dry and
effected signals from 0% to 100%.
DRIVE
Signal gain into the resonators. (The dry
level is unaffected.) Use this to reduce
the sensitivity of hot signals or overload
the input with graceful overdrive.
LFO
RATE/AMOUNT
The LFO speed ranges from glacially slow
to the lower range of audio rate
modulation, and the amplitude ranges
from zero to completely off the rails.
WAVE
Select between normal and random LFOs.
LFO is assigned to TUNE by default. Hold
WAVE to access the Mod Matrix, where you
can assign the LFO to other controls.
ENGAGE
Activates the effect. Hold until the bypass
LED blinks to toggle bypass modes. In trails
bypass, the resonators will ring out naturally
when the effect is turned off.
