Developer nakst re-released Altitude, a previously commercial hybrid synthesizer plugin, as freeware on August 1 — following the same pattern set by nakst’s Integrate synth, which went free back in December 2025. Two serious commercial instruments turning free within an eight-month span from the same small developer is a pattern worth noting on its own, separate from what either synth actually does.

What’s inside a genuinely hybrid engine
Altitude runs eight generators total, split between four virtual-analog oscillators and four sample-playback layers — meaning a single patch can blend classic subtractive synthesis tones with sampled material in the same signal chain, rather than requiring a separate sampler instrument layered on top. On top of that: two filters offering 15 algorithms, eight effect slots spanning 17 effect types, and two 24-step sequencers with built-in arpeggiators. The library ships with over 300 factory patches and 256MB of content specifically for the sample-based oscillators — a genuinely substantial starting point rather than a handful of demo presets.
Format support is somewhat unusual: Altitude runs as CLAP, AU, and a native FL Studio plugin, across macOS (Apple Silicon and Intel), Linux, and Windows — but there’s no VST3 version, which will matter for anyone running a DAW that doesn’t support CLAP or the native FL Studio format directly.
Why “free now” is more interesting than “free”
Free synth plugins are common; a developer taking a second previously-paid, full-featured instrument and releasing it free within less than a year of doing the same with another is a different signal. It suggests either a deliberate shift in nakst’s business model (away from per-instrument sales entirely) or simply that older instruments in a catalog get freed up once newer paid work supersedes them commercially. Either read points to the same practical outcome for musicians: a small developer’s back catalog of genuinely capable hybrid synthesis tools is becoming free faster than most users would expect from a working plugin developer.
