  • Drag-and-drop import for Ichiro Toda Synth1 presets (.sy1).
  • Native MIDI SysEx bank import for Roland JP-8000 and JP-8080 soundbanks.
• Mathematical Bitwise Combine Modes: Applies raw binary logic operators (AND, OR, XOR) directly to audio samples for digital distortion, bit-crushed textures, and pseudo-rhythmic harmonics.
• Comprehensive Modulation: 3 LFOs, 3 ADSR envelopes, and an 8-destination Modulation Matrix populated with 30 target presets.

Merging Virtual Analog Warmth with Wavetable Rigor
DiscoDSP Corona bridges classic hardware subtractive synthesis with digital wavetable manipulation. At its core are three versatile VA/WAVE oscillators capable of producing classic analog shapes or cycling through rich digital tables. For massive trance leads, euphoric chords, and cinematic swells, Corona incorporates the Super 7 and Super 7+ unison algorithms, modeled directly on the behavior and phase interaction of the legendary Roland JP-8080.

Rather than relying on standard sample blending, Corona allows oscillators to interact dynamically through its advanced operator combine modes. You can run oscillators into one another using frequency modulation, phase modulation, ring modulation, or mathematical operations that sculpt unique harmonic profiles before reaching the dual ZDF filter stages.

The Corona 7 Performance Sequencer
Version 7 introduces an overhauled arpeggiator and step sequencer. The sequencer transforms standard pitch manipulation into an interactive 12-semitone grid. With features like SEQ SYNC, live key transposition waits until the current sequence cycle finishes, eliminating jarring rhythmic jumps mid-measure. Coupled with direct Synth1 and Roland JP SysEx bank loading, Corona unites iconic synthesizer history with modern sequencing flexibility.

Sequencer & Arpeggiator Innovations:

• 12-Semitone Grid Interface: Replaces legacy volume/pitch sliders with an intuitive chromatic note matrix.
• Three Playback Trigger Modes:
  • SEQ HOLD: Plays sequence only while a key is physically held down.
  • SEQ TOGGLE: Latches playback on key press until the same key is struck again.
  • SEQ SYNC: Holds and queues key transposition until the running bar finishes its cycle to preserve phrase continuity.
• Interactive Step Recording (Edit > Record):
  • C4 – B4: Enter specific semitone pitch values.
  • C3: Tie / Syncopate notes into held ties.
  • D3: Insert musical rests / pauses.
  • E3: Step backward to overwrite mistakes.
• Algorithmic Bassline Generator (Generate Sequence): Creates playable bass grooves with locked musical scales, downbeat root anchors, and bar-end resolutions.
• Direct MIDI Export (Edit > Export MIDI): Exports pattern loops directly to standard MIDI files, translating internal ties, tempo tracks, time signatures, and routing M1/M2 macro lanes to MIDI CC22 and CC23.

Workflow & Interface Additions:

• Visual MIDI Learn: Controller CC badges overlay directly on assignable UI controls via Edit > MIDI, with hardware controllers organized by manufacturer.
• Mod Matrix Expansions: 30 dedicated quick-assignment presets across target drop-down menus.
• Mouse Wheel Navigation: Direct parameter adjustment via mouse scroll wheel across ArpSteps.

Oscillator Operation Modes (12 Phase / 16 Detune Modes):

• Classic Additive: Sums oscillator waveforms linearly.
• Subtractive: Inverts and subtracts secondary oscillator phases.
• Multiplicative: Multiplies sample amplitudes for intermodulation harmonics.
• Pythagorean: Scales harmonics according to classical pythagorean intervals.
• Hard Sync: Forces oscillator phase resets locked to the master oscillator cycle.
• Ring Modulation (RM): Generates metallic, bell-like sum-and-difference sidebands.
• Phase Modulation (PM): Modulates oscillator phase dynamically for classic FM-style timbres.
• Bitwise Logic Modes (Standard & Absolute AND / OR / XOR):
  • Applies binary logic operations directly to 16-bit waveform sample data.
  • Generates abrasive digital crunch, digital aliasing, and pseudo-rhythmic harmonic textures impossible to achieve with standard filtering.

System Prerequisite:
This release requires TEAM R2R System v1.5.3 (included in the distribution package). Ensure the R2R System runtime is deployed and active before installing the plugin.

Installation Steps:

1. Open the included R2R folder and run TEAM R2R System v1.5.3 Setup.exe as Administrator (Right-click -> Run as administrator).
2. Run the main installer (DiscoDSP_Corona_v7.1.0_Setup.exe) as Administrator.
3. Select your desired plugin formats (Standalone, VST, VST3, AAX) and target installation paths.
4. Complete the installation wizard.
5. Launch Corona in Standalone mode once to initialize factory soundbanks, wavetable caches, and MIDI profiles.
6. Open your DAW, perform a plugin rescan, and load Corona on an instrument track.

Importing External Presets:

• Synth1 Patches: Drag any .sy1 preset file directly from Windows Explorer onto the Corona interface to convert and load it.
• Roland JP-8000 / JP-8080 Banks: Go to File > Import SysEx, select your hardware .syx bank file, and Corona will automatically parse and convert compatible patch settings.

Frequently Asked Questions (FAQ):

• Q: How does bitwise combining differ from regular wave distortion?
  A: Bitwise modes manipulate raw binary bit patterns (0s and 1s) representing sample amplitudes. Instead of smooth rounding or hard clipping, it generates non-linear digital artifacts and stepped harmonic overtone series.
• Q: Can I run Corona on older Windows versions like Windows 7?
  A: Version 7.1.0 targets modern 64-bit architectures and requires Windows 10 or Windows 11 for hardware-accelerated GUI rendering and modern VST3/AAX host compliance.
