Synthica: a free synth that shows you how sound works

// Lab Notes By Piruz Labs · 21 May 2026

Most synths hide what they are doing behind hundreds of controls. Synthica does the opposite.

It keeps the classic signal path simple and visible, and it draws the sound, as a waveform and a spectrum, in real time, so you can see what a filter, an envelope or an LFO actually does. It is the synth I wish I had when I was starting.

See the sound

Turn the cutoff and watch the waveform change shape. Move an envelope and watch the sound rise and fall. The fastest way to understand synthesis is to see it happen, not to read a manual about it.

The classic path, made clear

Two oscillators plus noise, a mixer, a resonant filter, an amplifier, two ADSR envelopes and an LFO, with mono and poly modes. Nothing exotic, just the real building blocks of subtractive synthesis, laid out so the relationships are obvious.

Free, for anyone starting out

Synthica will be free, forever. Not a limited demo, a real first instrument, for anyone curious about how synths work. Because a first instrument should not cost anything.

Why free

From every paid Piruz Labs plugin, a portion goes toward putting first instruments in more hands. Synthica is the same idea in software form: lower the doorway, and let more people walk through it.
