How it connects
Portfolio advantageFusion Synth’s engine is also what Fusion Keys plays through, so the two products improve together. Fusion Synth loads in Fusion Audio Studio as a plug-in, as Fusion’s other instruments do.
What Fusion Synth brings together.
WHAT IT ENABLESOne sound engine for synthesizer patches and for Fusion Keys’ instruments. Fusion Synth is in development and has not been released: what is marked in development works in a development build on Windows, and what is marked planned is not built. The picture is that build’s own window.
Sixty-one factory patches
01 · IN DEVELOPMENTEvery factory patch plays in the C++ engine, each checked to match the engine it replaces sample for sample.
Twelve controls
02 · IN DEVELOPMENTTwelve controls shape the patch you are playing.
One engine, two products
03 · IN DEVELOPMENTFusion Keys’ pianos, organs, and accordions are played by this engine.
Your own sounds
04 · PLANNEDA preset library, saving your own patches, macro controls, and SoundFont and SFZ instruments.
A plug-in and an application
05 · IN DEVELOPMENTFusion Synth is a VST3 plug-in for an audio workstation and an application that runs by itself on Windows, played from a MIDI keyboard or the computer’s keys. The plug-in passes the VST3 validator and loads and plays in Fusion Audio Studio.
Installers and more systems
06 · PLANNEDSigned installers, a CLAP plug-in, and versions for Fusion OS and Android are planned. It has not yet been tried in audio workstations from other companies.
