The Dream Sounds “Harmony” series are a collection of computer UI sounds made with a MIDI synth program called Accordion and with simple homemade noises.
Most of the sounds are made of different digitalized instruments thanks to a MIDI sound font called OmegaGMGS2. Their purpose is to notify the user of something on the computer that has happened like an error, a message, an alert, etc.
They’re free to download and use. Just give credit to me and don’t claim them as yours, thank you.
