The ideas inside every synth, ready to play
Each example is a real Maru instrument, the same ones our guides are built on. Pick one, play it with your computer keyboard and move a single control. That's how every guide starts.
Why we're building this
The answers exist. They're just scattered.
We build instruments, effects and research tools for musicians. The best conversations we have aren't about features. They're about why a chord sounds muddy, why a compressor pumps, or why a separated vocal sounds underwater.
Those answers are spread across forum threads, plugin manuals and textbooks that never let you hear what they describe. We want one place where the music, the sound and the tool are explained together, and where you can play every idea as you read about it.
- Judgment you can take anywhere
- Know why a technique works and where it stops working, so you can decide for yourself instead of copying a preset. It applies in any DAW and with any plugin.
- Connections other tutorials miss
- The beating in a detuned chord is the shimmer of a chorus pedal and the tuning of a Balinese gamelan. Our guides link theory, sound design, mixing and code, so one idea leads to the next.
- Something you made
- Every guide ends with a preset, a phrase or a patch that you keep, open and change.
- Straight answers about AI
- When a guide uses machine learning, we show what the model really does, where it shines and where it's guessing.

The guides
From your first listening test to your own instrument
Five families of guides. Follow one as a path or dip in where you're curious; each family page describes every guide in it. We publish them one at a time, and share early drafts for review.
