The Sosnowski Synthesizer is a software instrument that emulates classic analog synthesis with a user-friendly interface. It is available both as a standalone player and a VST plugin, compatible with various digital audio workstations. Featuring 128 onboard preset sounds along with additional external sound files, this synthesizer is designed to excel in live performance settings as well as studio production, sequencing, and notation environments.

Its layout is clean and logically organized, making it accessible to beginners while offering deep control options that appeal to experienced producers. The sound engine is built around four oscillators, each capable of generating sine, triangle, sawtooth, square, and noise waveforms. These oscillators feed into a multi-mode filter with its own envelope, complemented by dual adjustable low-frequency oscillators for rich modulation possibilities. A final envelope shapes the output before it reaches the onboard effects section.

The sound treatment section includes stereo chorus, reverb, echo, and automated panning, all fully adjustable from the interface. Additional tools such as an onboard velocity-sensitive keyboard, parametric equalizer with visual feedback, and a built-in oscilloscope support detailed sound design and performance control. With MIDI compatibility, 32-voice polyphony, and a powerful preset manager, the Sosnowski Synthesizer offers a comprehensive and affordable solution for musicians and producers seeking analog-style synthesis in software form.
