– Two pairs of state variable filters in stereo.
– Continuously morph between Lowpass, Bandpass and Highpass.
– Continuously route/mix between parallel and serial configuration.
– Two audio-rate LFO modulating filter cutoff.
– Filter cutoff and LFO rate can be mapped to accurate note frequencies for external Midi / CV automation.
– All internal parameters can be assigned to hardware knobs as macros.
– Up to 16+1 patches can be packed into one user unit.
– Each patch can be continuously morphed into the next.
– Carefully optimized algorithm, lighter than the factory flanger.
– Available as any of the effect types (modulation / delay / reverb).


Editor Parameters

Project Name:
Name the project in 10 characters, it will be used as both the filename and FX name displayed on the hardware.
Export Button:
Export the current project as a ready to use user-unit file following the “export format” setting.
Export Format:
The target fx slot and platform to export. The choices are:
Mod: modulation fx
Mod(Bi): bi-timbral mod fx for Prologue
Del: delay fx
Rev: reverb fx
MnlgXD: Minilogue XD file extension
NtkDig: Nu:tekt Digital (NTS-1) file extension
Prlg: Prologue file extension

Patch Edited:
The current patch being edited by the editor.
Patch name:
Double Click the box to edit patch name. It’s only visible in the editor, won’t be displayed on the hardware.
Copy patch:
Select a patch slot to copy from, overwriting the current edited patch.
Patch Monitored:
Select the patch you are monitoring. “Currently Edited” means just that, “Knob Position” monitors patch selection corresponding to the knob and range settings just like on the hardware.
Patch Select Knob:
Choose which knob you want to be used for patch switching on the hardware.
Knob Select Range:
The range of patches you want the knob to select. To disable patch switching, simply select any of the knobs, set the same patch for range, and disable Patch Morph.
Patch Morph:
Turns on patch morphing mode, parameters will be morph between two settings of consecutive patches. To hear the effect, make sure you set Patch Monitored to Knob Position. You can check the current morph position at the Patch Position monitor label.

Monitor Knobs “A/Time,” “B/Depth,” “shift-B”
The three knobs on the bottom-right are simulators of corresponding knobs on the hardware for monitoring purpose.


Engine Parameters:

F1/F2 Cutoff:
Cutoff frequency of each filter in Midi note scale, you can check the calculated hz frequency in the Engine Monitor.
F1/F2 Resonance:
Resonance amount of each filter.
F1/F2 State:
Continuously morph between Lowpass (0%), Bandpass (50%) and Highpass (100%).
F1/F2 LFO Freq:
Audio-rate LFO modulating the cutoff frequency of each filter.
F1/F2 LFO Amt:
LFO amount in semitones, corresponding to midi note scale used in Cutoff.
F2 Input Mix:
Crossfades the between Dry signal and Filter 1 output signal.
Output Mix:
Crossfades the final output signal between Filter 1 and 2 output.
For parallel configuration: set F2 Input Mix to 0%, Output Mix to 50%.
For serial configuration: set F2 Input Mix to 100%, Output Mix to 100%.


Parameter Macro Settings

Top-Right Selector: Knob Assign
Choose which knob will be controlling this parameter.
Top-Left Selector: Parameter/Macro Mode
– Fixed: means the value is fixed throughout this patch.
– Lin-Lin: parameter value follows knob movement linearly in the range specified by the three sliders corresponding to 0%, 50% to 100% position of the knob. For example, to recreate the shift-Depth dry/wet control of factory onboard delay/reverb, follow this setting:

– Lin-Fix
– Fix-Lin
– FIx-Fix
These are similar to the Lin-Lin setting, but with parameter value fixed on either or both side (0%~50% and 50%~100%) of knob position.

Midi mapping for CC control
Oct/V mapping for CV control
Parameters in “mid” are scaled to midi note frequency, that means if mapped carefully they can be automated by midi CC or CV voltage to pretty accurate note frequency. Below is the example setting for CC (left) and CV Oct/V(right).
