Tones.fm – Make synth music

In plain words

Tones.fm is a collaborative music-making platform where users create synthesizer-based music by clicking dots to form note patterns. Users can load demo tones, remix existing ones, and adjust settings like key, scale, and drum tracks independently for each pattern. The platform is designed for anyone interested in composing simple electronic music through an accessible, open interface.

From the sources

Tones is a simple, open, collaborative music-making platform. All tones are created using the built-in synthesizer. Load a demo tone from the browse menu, or find one you like in the charts on the home page. Remix to create your own tone. Create a pattern of notes to play by clicking the dots. Each row plays a note from the scale chosen in the Notes menu (see below). Change the key, scale and offset, and toggle the drum on / off. These settings are applied to the currently selected pattern, so you can drop the beat or change the key etc during the sequence. Use the sequencer to compose a longer tone of multiple patterns, each with their own notes, key, scale, repeat length and drum setting.…from tones.fm
