Synapse Audio Obsession delivers the legendary Oberheim OB-Xa polyphonic analog synthesizer sound through revolutionary individual voice control technology never achieved in software emulation before.

This vintage analog synthesizer plugin meticulously models voltage-controlled oscillators, filters, and amplifiers from the iconic 1980s hardware that defined classic synthwave, film scores, and progressive rock productions.

Obsession goes beyond simple circuit modeling by implementing comprehensive per-voice parameter control, allowing each voice board to differ noticeably creating the organic, lively sound vintage analog polysynths are famous for. Combined with modern enhancements including 16-voice polyphony, stepped LFO freehand drawing, shimmer reverb effect, and dual-part architecture, Obsession bridges vintage character with contemporary production workflow.

Pre-activated and ready for immediate music creation, this professional synthesizer plugin includes 420 factory presets designed by leading sound designers for instant inspiration across multiple genres.

❓ Frequently Asked Questions

Q: What makes Obsession’s individual voice control groundbreaking compared to other OB-Xa emulations?
A: Obsession allows unprecedented per-voice parameter adjustment for cutoff frequency, amplifier release, oscillator scaling, filter scaling, and pan position. Each of the 8 or 16 voices can be individually tweaked, creating organic variations impossible with traditional synthesizer plugins. This mirrors hardware trim pot adjustments found on original OB-Xa voice boards, producing the natural inconsistencies and lively character that make vintage analog polysynths sound alive rather than static.

Q: How does the Organic knob simulate temperature-dependent fluctuations?
A: The Organic knob simulates vintage hardware behavior where temperature changes affect oscillator pitch stability, filter cutoff accuracy, and envelope timing. As vintage analog synthesizers warm up, component drift creates subtle pitch wavering and filter movement. Obsession recreates this controllable instability, adding expressive character and preventing the overly perfect, sterile sound typical of digital synthesizers. Higher settings increase drift amount for maximum vintage authenticity.

Q: What is shimmer reverb and why is it included?
A: Shimmer reverb, coded by audio expert Mirko Ruta, blends reverberated signal with octave-up transposed copy creating ethereal, lush atmospheres perfect for pads, leads, and cinematic textures. The Regen function feeds transposed signal back creating multiple cascading octaves producing expansive depth and richness. This premium reverb effect eliminates need for external processing, delivering professional shimmer sounds directly within the synthesizer for immediate inspiration.

Q: Can I use stepped LFO with freehand drawing for rhythmic sequences?
A: Absolutely. Obsession’s stepped LFO control allows creating rhythmic, tempo-synced modulation of virtually every sound parameter with freehand drawing for arbitrary shapes. Draw custom modulation curves directly in the interface, snap to tempo sync, and assign to filter cutoff, oscillator pitch, panning, effect parameters creating evolving generative patches. This powerful feature enables complex rhythmic sequences and organic movement impossible with traditional LFO shapes.

Q: Does Obsession support dual-part architecture and keyboard splitting?
A: Yes, Obsession features comprehensive dual-part engine with Single, Dual, and Split modes. Single mode plays one patch normally. Dual mode layers Part A and Part B simultaneously for thick stacked sounds combining different patches. Split mode assigns Part A and Part B to separate keyboard regions creating performance setups with bass in lower octaves and leads in upper octaves, perfect for live performance and complex arrangements without multiple plugin instances.
