Regency: multi-tiered phase distorting synthesizer

Regency offers a novel method of synthesis, based off traditional phase distortion synthesizers. Each of the two generator layers has three editable multi-segment curves. These curves are applied to distort the phase of the generator in series, in modulatable amounts. There’s also a wide range of modulation options and effects, as well as a multi-mode ladder filter to provide a great number of sound design possibilities.

Super modulation.
Regency has a wide range of modulation units. As well as the four envelopes and three multi-segment LFOs, there are two math modulators, which let you shape and warp other modulation sources.
Each modulation unit has several built-in assignment slots. And there’s also a 6 slot modulation matrix for making additional articulations.

The final touches.
There are three effect slots, each of which can contain any of the six effect units included it.
You can reorder units, and even use the same unit multiple times in your effect chain.
Available units: bitcrusher, flanger, pattern delay, trancegate, delay line, five-band EQ.

Highly tuned performance.
Regency automatically detects the features on your CPU and selects the most optimal code, to ensure the best performance.
With native support for Intel processors over a decade old all the way up to the latest Apple Silicon processors.

The latest technology.
Regency leads the way to the future of audio plugins, built from the ground up for the new plugin format CLAP.
CLAP is based on an extensible architecture. If both your host and the plugin support a given extension, you’ll get access to its advanced features.
Regency already supports many extensions, such as polyphonic modulation, preset discovery, parameter indication, remote controls and more.

Product specifications:
2 phase distortion generators
6 multi-segment wave graphs
Ladder filter with 4 modes
4 envelopes (1 ADSR and 3 DAHDSRs)
2 math modulators
3 multi-segment LFOs
6 slot modulation matrix

Cardinal Rack is a free and open-source virtual modular synthesizer plugin, available as JACK standalone and AU, LV2, VST2 and VST3 audio plugin for FreeBSD, Linux, macOS and Windows.
It is based on the popular VCV Rack but with a focus on being a fully self-contained plugin version.

More specifically, this is a DPF-based plugin wrapper around VCV Rack, using its code directly instead of forking the project, with the target of having a proper, self-contained, fully free and open-source plugin version of Rack.
See the why section below for the reasons Cardinal Rack exists, also for frequently asked questions check this FAQ document.

Cardinal Rack contains Rack, some 3rd-party modules and a few internal utilities all in a single binary.
All “Core” modules from Rack have been replaced by Cardinal equivalents, simplified to better work for an audio plugin.

Cardinal does not load external modules and does not connect to the official Rack library/store.
All VCV branding has been removed (to the best of our knowledge) in order to avoid any trademark issues.

The VST3 version is in progress, already part of the build but still experimental.

Stable release
Cardinal releases have official builds for Linux, macOS and Windows.
There are Linux builds for various architectures (armhf, arm64, i686 and x86_64), macOS “universal” (arm64 + intel) and Windows 32 and 64bit builds. Both macOS and Windows builds have an installer.

Plugin variants
Cardinal Rack provides 3 plugin variants – “main”, Synth and FX.
They are all equivalent in performance and behaviour, with only the IO and metadata that changes.
This is because some hosts are very strict on which plugins are allowed as instruments vs FX, so separate variants of the same plugin are needed.

FX and Synth variants both have 2 audio outputs, while “main” has 8.
All variants have MIDI input and output support.

Main
This variant provides 8 audio inputs and outputs and 10 CV inputs and outputs.

NOTE: Due to AU and VST2 formats not supporting CV ports, this variant is not available for those formats.

Synth
This variant provides 2 audio outputs but no audio inputs or CV ports.
Plugin type is set as “instrument”.

FX
This variant provides 2 audio inputs and outputs, but no CV ports.
Plugin type is set as regular “effect”.

Screenshots
Because people will ask for it. It is, well… Rack.
But a couple of modules background’s have their colors flipped, because damn we want proper dark mode!

Included modules
At the moment the following 3rd-party modules are provided:

Linda Audio releases Digimorph VST – experimental digital synthesizer. It does not emulate any real hardware, instead it brings original combination of substractive and additive synthesis with powerful modulation matrix. On top of that there are quality master fx (chorus, delay, reverb and two saturations) and arpeggiator. Digimorph is capable of wide range of sounds from ethereal evolving pads to gritty chiptune leads, raw digital basses or synth arpeggios, beatiful organs or some fm-like sounds. There are 200 presets included, covering all of these areas. Digimorph is great for modern electronic music, soundtracks, chiptunes, or anywhere where you need to add some original and interesting digital sounds.

The core of Digimorph is additive non-band limited oscillator which can contain mix of 16 harmonics. Its shape can be sinus, triangle, pulse, saw and multi-pulse. This can be run in monophonic, polyphonic (max 16 voices) or live-arp mode. In live-arp mode presed notes are automatically generating arpeggio sequence.

Additive section (violet) allows to set gains of harmonics. Other parameters are Phase shift – adjusts phase offset added to harmonics, Harmonics slope – adjusts how fast harmonics decay or rise in time and Harmonics lfo – introduces modulation to harmonics gains.

Each oscillator has several classic parameters (yellow) such as amp, pitch, fine tune, pan, glide and spread (random spread of notes in panorama).

There are some more sound-character parameters (orange section). Pulse width adjusts pulse width for pulse, saw and multi-pulse shapes and can be applied in two different modes – classic and harmonic. Wave shaper introduces wave-folding by sine wave. And Ring mod adds ring modulation by sine or saw wave with adjustable speed (this can be free or locked to harmonics).

In gray section there are sound degradation parameters – Bit div is sample rate divider, Bit feed introduces feedback of samples reduced by Bit div and Pitch noise adds random pitch modulation with variable speed.

After each oscillator there is one multi-mode, state-variable resonant filter (red section) which can be continuously switched between low-pass, band-pass and hi-pass with adjustable frequency and resonance.

Each oscilator can be modulated by two ADSR envelopes (one for amp envelope and second for anything else) and two LFOs. It can be also modulated by note velocity, modwheel (can be switched to listen also to aftertouch controll) and arpeggiator. LFO’s amp and speed can also be modulated by ADSR 2 and by modwheel. All available modulations can be set directly by sliders in the center of the Digimorph gui

Arpeggiator is a tempo synchronized step sequencer of maximum 16 steps. You can adjust sequence length, loop start and tempo. For each step you can adjust oscilator pitch, shape and modulation source. Modulation source can be interpolated.

In Live-arp mode you can select from several sequence shapes. If Arp-on switch is engaged, shape and mod arpeggiator modulations are applied.

At the end of the sound generator chain there are several master fx (blue section). Available is Chorus, Ping-pong delay, Reverb and two distortion modules (DIST1 adds more subtle harmonic distortion while DIST2 applies tube saturation).

Digimorph also provides undo, redo, A/B and 200 presets.
