Q is a free synthesizer plugin designed for Windows, offering a rich palette of sound creation options. It features two virtual analog oscillators alongside a phase distortion oscillator and a frequency modulation oscillator with five operators. Each oscillator can be routed flexibly, either directly to the amplifier with individual panning or through one or both of the two available filters, enabling complex sound shaping.

The sound design possibilities expand with four envelopes dedicated to modulation, amplitude, and each filter, plus two filters—a lowpass and a multi-mode filter that includes distortion and shaping options. These filters can be arranged in parallel or serial modes, allowing for intricate tonal variations. Four LFOs and four modulation sequencers provide dynamic control over parameters, with each offering retrigger options and adjustable speeds that can synchronize with the host tempo or run independently.

Additional effects such as a bitcrusher for lo-fi textures, delay, and reverb are included to enhance the sonic output. The modulation wheel’s targets are customizable, giving performers hands-on expressive control. As a freeware instrument, Q invites users to integrate it into their projects freely and share their custom presets, fostering a community of sound enthusiasts who appreciate its depth and flexibility.
