Build North Coast's complex VCO kit for a journey to the East or the West, or bring it home as a stable foundation for any Eurorack. The module contains two triangle-core VCOs, each with four waveforms and Eurorack-standard V/octave pitch CV. 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.
This is one of the easiest complex VCOs to build. It's all through-hole, without flying wires or complicated physical design. The exponential converter uses premium AD633 analog multipliers and a THAT320 transistor array to give excellent temperature stability in a simple, foolproof build. There are only four trimmers to adjust (one tracking and one sawtooth shape per oscillator) and they don't interact. The circuit is simple for the range of features it offers, and solidly documented. With two oscillators and many modulation options, building just one kit puts you well on the way to a complete DIY Eurorack synthesizer.
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.
