This is just a quick explainer of how I create low-cost “piano-esque” sounds, which I often use in generative patches. No one is going to confuse this for a concert grand any time soon, but with a little reverb or delay, in the mix with some other voices, it can be reminiscent enough of piano to get the job done. All it takes is a self-FMing sine wave, a VCA, a specific envelope, and some filtering — the total cost is under 10% of the CPU.
This deviates a little from the other Zynth Zekret videos in that it doesn’t really cover a type of synthesis; this is just a patching technique that I use quite often and thought others might be curious about. I hope you enjoy!

Really love this approach! It’s always cool to see creative ways of building convincing “piano-esque” textures with minimal CPU use. The idea of self-FMing a sine wave to shape tone and character is clever — definitely going to try blending it with some ambient delay for that dreamy, generative vibe.

Geometry dash subzero is a rhythm-based platformer where players steer a geometric cube through a neon landscape with spikes, traps, and more. The Geometry Dash spin-off has three distinct levels: Press Start, Nock Em, and Power Trip. Each features upbeat music that matches the increasingly challenging obstacle courses.
