Everything You Need to Know About GForce Oberheim OB-1: A Must-Have Synth Plugin

Reviving a Rare Classic with Modern Sonic Versatility.

GForce Software’s Oberheim OB-1 plugin is a meticulously crafted emulation of the 1978 Oberheim OB-1, the first programmable monophonic synthesizer. This rare gem, often overshadowed by synth icons like the Minimoog and MS-20, was groundbreaking in its time for introducing patch storage. GForce has not only recreated its unique analog character but expanded it with powerful modern features, making it a versatile tool for contemporary music production.

Sound Quality

The OB-1 plugin retains the rich, aggressive tonal character of the original while adding modern enhancements. Its dual oscillators support waveshaping and sub-oscillators, delivering a range of sounds from warm basses to snarling leads. The signature Oberheim filter—now offering 2-pole and 4-pole modes—provides resonance options that excel at both smooth and screaming sounds, ideal for cinematic, ambient, and electronic music styles.

Features

1. Expanded Polyphony
   The original OB-1 was monophonic; the plugin expands this to include 16-voice polyphony and unison modes, enabling lush, massive sounds.
2. X-Modifier System
   A standout addition, the X-Modifier system allows extensive modulation of almost any parameter using X-LFO and X-ADSR controls. This simplifies complex sound design, making it accessible without sacrificing depth.
3. High-Pass Filter
   A new high-pass filter adds precision for modern mixes, enhancing the original’s sonic palette.
4. Arpeggiator and Sequencer
   The 16-step sequencer offers independent control of pitch, velocity, and modulation, with randomization and probability features that encourage creative experimentation.
5. Built-in Effects
   Integrated chorus, delay, and reverb effects further expand the plugin’s versatility, providing atmospheric and polished textures.
6. Macros for Real-Time Control
   Four programmable macros allow users to control multiple parameters simultaneously, perfect for expressive live performances or dynamic automation.
7. Intuitive Interface
   The UI is fully scalable and user-friendly, balancing vintage authenticity with modern workflow enhancements.
8. Extensive Preset Library
   Featuring over 300 presets crafted by top sound designers, the OB-1 covers a broad spectrum of styles, from nostalgic tones to modern experimental sounds.
