Neptunely is a smart sample generation engine and a procedural music production library. It takes midi files as input and generates original samples that fit with your compositions. It can also be used to generate full songs and albums with given parameters: Listen to a demo.

I am looking for producers and musicians to try it out and help with the pattern library!

Send me a chord progression as a midi file and I’ll send you back a sample pack generated by the engine. If you want to contribute to the pattern library, I am currently looking for expressive bass, drum, and keys patterns as midi files. Until the full site is up, please send files to
