A living sound instrument
Every season
has a sound.
A two-layer sampler with a globe at its centre — move it, and the whole instrument turns through the year.
Listen
One phrase. Ten presets.
The same MIDI through every preset, rendered by the plugin exactly as it ships. Pick another one and the sound changes mid-bar — the music doesn't stop.
Playing
Plays like an instrument.
A sample library plays back. 4seasons responds.
Effects
Five effects,
built as pedals.
Inside
Made from real sound.
Analog synths breathing through their filters. A real piano, played soft and hard. Real voices. Field recordings underneath it all. The heart of 4seasons moved air before it became a sample — that is where the warmth comes from, and why it feels like something instead of just sounding like something.
Alongside the hardware: sounds designed from scratch in synths and resampled through effect chains.
One-time purchase
Let the year
play through you.

Questions
A few things
people ask first.
The full list, with everything on activation and moving computers, lives on the support page.
What do I need to run it?
- Formats
- macOS: VST3, Audio Unit, standalone application · Windows: VST3
- System
- macOS 10.13 (High Sierra) or later, Intel and Apple Silicon · Windows 10 or later, 64-bit
- Disk space
- 1.05 GB for the sound library. It is a single file, so you need that much and no more.
No dongle, no iLok, no account. A licence key and one online activation, and that is the whole of it.
Can I use the sounds in commercial releases?
Yes. You may use the software and every sound in it in your own music productions, including commercial releases — no further licence fees, no revenue share, no credit required. That covers commissioned work, film, advertising, games and library music.
What is not allowed is passing the sounds on as sounds: reselling or publishing the library or individual audio files, or using them as part of another sample pack, preset pack or instrument — anywhere the sound itself is the product being sold rather than part of a music production. You may share your own presets, as long as they contain no audio files from the library.
The rule of thumb, from the licence terms: make as much music with it as you like, do not resell the sounds themselves. The binding wording is § 4 and § 5 of the licence terms.
Is there a subscription?
No. One payment, and updates within version 1 are free. Beyond version 1 there is no claim to future features or later versions — see § 2 of the licence terms.
How many computers can I use it on?
The key may be active on two computers at the same time, and you can release an activation from inside the plugin whenever you like — so two at a time, not two forever. See § 3 of the licence terms, and the FAQ for how to move one.
Will it run in my DAW?
It runs wherever VST3 or Audio Unit plugins run. On macOS Logic Pro uses the Audio Unit; Ableton Live, FL Studio and Reaper load the VST3, and there is a standalone application if you want to play it without opening a DAW at all. On Windows it is the VST3.
One thing catches nearly everybody: restart your DAW completely after installing. A plugin rescan alone is often not enough, and 4seasons then looks as if it had not installed.
