Pulsar Modular - R52 Baxandall v1.0.0 VST3, AAX for Windows

• Unified Feedback Network: Bass and Treble controls operate as two interactive arms of a single feedback loop rather than isolated frequency bands. Boosting both shelves naturally recesses the midrange, while cutting both pushes mids forward.
• Integrated Tube-in-Loop Topology: The valve is positioned inside the curve-generating loop itself. Input drive dictates valve presence, and boosting treble drives valve harmonics specifically within the boosted spectrum with no harsh clipping point.
• Real-Time SCOPE Visualizer: Interactive display illustrating the precise phase and curve interactions between feedback arms as controls are adjusted.
• Interactive Impedance Controls:
  • SOURCE: Variable source impedance from 0 Ω to 250 kΩ (marked with the original 1952 operating boundary up to 10 kΩ; default: 0 Ω).
  • LOAD: Selectable amplifier output damping into a fixed 15 Ω monitor load (OFF, 0.7, 1.5, 2.5, 3.5, and 7.0 Ω; OFF provides complete stage bypass).
  • SHELF: Continuous interpolation between Baxandall's two original published high-frequency corner specifications.
• Multi-Channel & Immersive Audio: Supports any channel configuration from mono up to multi-channel immersive formats, running an independent modeled valve circuit per channel.
• Flexible Channel Routing: Stereo instances support Stereo, Mid, Side, Left, and Right channel modes, complete with an ISOL solo audition function.

Selectable Circuit Topologies:

• 1952: The original historical design featuring the SP61 pentode in the active loop.
• 1957: The updated revision based on the ECC81 (12AT7) dual-triode valve.
• 1957 ALT: The 1957 circuit topology driven by the SP61 pentode.

AMP Path:

• Engages the dedicated amplifier in the LOAD path (requires LOAD enabled; available in Mono/Stereo, excluded in Mid, Side, L, R modes).
• Operates in real-time up to 96 kHz. At project sample rates above 96 kHz, the AMP path automatically utilizes a freeze/render/export mode while routing standard LOAD for live monitoring.
• Preserved across user presets, DAW sessions, and A/B comparison slots.

• Internal Processing: Pure 64-bit floating-point precision for bit-identical offline bounces across matching sessions.
• Automatic Oversampling: Continuously active linear-phase oversampling that automatically scales to match session sample rates.
• Latency & PDC Reporting:
  • 44.1 kHz / 48 kHz: 91 samples (~2 ms)
  • 88.2 kHz / 96 kHz: 71 samples
  • 176.4 kHz / 192 kHz: 0 samples
  • Fully reported to host DAW for automatic plugin delay compensation (PDC).
• True Bit-Accurate Bypass: Dedicated IN/OUT processor delivers click-free, bit-transparent throughput while matching active latency to eliminate phase offsets during A/B evaluation.
• Automation Parameters: Fully automatable Bass, Treble, Shelf, Source Impedance, Load, Input (dB), Output (dB), and In/Out. (Circuit Version, Matching, and Channel Mode are stored with the session file).
• Preset File Management: Native .R52Preset files dynamically scanned from:
