"Deep dive into the Local Parks oscillator."
Local Parks got its first mention back in May of 2023 during SUPERBOOTH23.

"The Pittsburgh Modular Local Parks is drawn from our waveform manipulation research where advanced approaches to wave shaping throughout the oscillator showcase new sounds and unique waveforms. A full compliment of robust waveforms and modulation options paired with unmatched waveshaping creates a truly modern analog oscillator.
Our in-depth experimentation has created pulse waves which can be manipulated in multiple dimensions utilizing both Pulse Width and Pulse Shift. Pulse Shift creates an adjustable “step” within the pulse wave to further enhance the harmonic content of the wave. The wave used to create the pulse can be switched between sine and saw for additional sonic variation.
The Blade Wave is a morphing saw wave pitched one octave above the core frequency of the oscillator that smoothly shifts back to the core frequency as it changes shape. This creates a chorus-like effect on the sound of the Blade Wave without ever falling out of tune.
A Binary Logic waveform further expand the distinct sonic palette of the Local Parks. First utilized in our Narwhal Cymbal module, this waveshaper uses analog binary logic to create everything from gate effects to atonal bell like tones. The pulse and blade waves can be summed with the binary output for even more complex results.
Local Parks includes a built-in voltage controlled modulator to handle the bulk of modulation needs. This ensures that Local Parks can be a dynamic oscillator that produces evolving, high harmonic sounds within any eurorack setup."
