North Coast's complex VCO is comfortable on a journey to the East or the West, while providing a stable foundation at home in any Eurorack. The module contains two triangle-core VCOs, each with four waveforms and standard V/octave control. As basic VCOs running independently these can be the heart of a traditional subtractive East Coast synthesizer. But the Middle Path's oscillators can also be used together, with or without sync, to drive its unique multi-output Gilbert-style sine shaper. The shaper, which can also take external input, offers wave shaping, distortion, folding, phase modulation including through-zero, and imitation stereo. These effects take the sound into West Coast territory.
The design emphasis is on harmonious combination of simple principles. The exponential converter uses premium analog multipliers and a transistor array to ensure temperature stability without fiddly adjustments or hard-to-control "tempco" resistors; it should provide consistent tracking, and especially between the two oscillators, without needing to warm up. The triangle cores are intrinsically frequency-accurate without needing extra circuitry to compensate for reset time. The sine shaper includes our own novel quadrature modification which can be used to generate a stereo signal or in combination with other modules to create frequency shift effects. The sync circuit joins the oscillator cores in another way with a selection of soft and firm modes.
The Middle Path is available as a pre-built 24HP Eurorack module or a DIY kit. It may be the only VCO path you need walk in this or multiple lifetimes.
