Lines is an effect plugin that crosses borders: it can be used as a creative mangler of all kinds of signals, ranging from lo-fi telephone sounds, lush phasing, warm distortions, crushing feedback, ring modulation and unique frequency shifting. But even without any input, it can be an experimental synthesizer based on feedback, allowing for a wide range of inspiring rhythms, pulses, and organic soundscapes. If you combine input and internal engines an unheard spectrum of sounds appears.
