“4Front E-Piano is a small single sound instrument without any settings that reproduces a timbre, which is similar to DX-7 type e-piano. It is available as VSTi for Windows, and as an AudioUnit, VSTi and RTAS for Mac (see enclosed readme file).
This instrument is small on memory and CPU usage and was found useful by many users and software developers as a plug&play e-piano module, which does not require any configuration or adjustment.”
Great simple to set up electric piano, for anyone who wants a vintage DX-7 sound.
