Tobinski - Dual LPG/VCA

Tobinski Dual LPG/VCA - brings together Buchla and Moog designs.

The Tobinski Dual LPG/VCA combines two classics of the synthesizer world in one compact Eurorack module: a Buchla-inspired Low Pass Gate (LPG) and a Moog-based Voltage-Controlled Amplifier (VCA). Perfect for organic dynamics and precise amplitude control - a real workhorse for amplitude control.

The LPG is built on a vactrol-based circuit that elegantly combines volume control and filtering. The result: warm, woody textures, percussive plucks and natural decays - ideal for dynamic, lively patches. The VCA, inspired by the legendary Minimoog, delivers clean, distortion-free amplification with plenty of headroom, perfect for subtle volume modulation or more intense signal shaping.

Thanks to separate CV inputs for amplitude and filtering, the module can be used in a variety of ways and flexibly controlled with envelopes, LFOs or sequencers. It is also very compact considering its range of functions. Whether classic subtractive synthesis or experimental sound design - Tobinski's Dual LPG/VCA brings together two legendary concepts and ensures deep, musical expressiveness.

Features

• Two independent LPG/VCA circuits
• VCAs inspired by Dr. Bob Moog’s classic soft-saturation design
• LPGs modeled after Don Buchla’s iconic circuit
• Two switches to toggle between VCA and LPG mode
• Two 3-way toggle switches to select between low-pass, combo, or gate mode for the LPGs
• Two sliders to control input level in VCA mode (saturation kicks in above 50%) or adjust filter/gate opening in LPG mode
