Gridline is a free, open source music workstation built around patterns.
Sketch beats in the channel rack, write melodies and chords in the piano
roll, arrange patterns, audio and automation in the playlist and mix
everything on a full mixer with built-in instruments and effects.

It hosts VST3, CLAP, VST2 and LV2 plugins, runs as a VST3 and CLAP plugin
itself (the Gridline Suite brings its instruments and effects to other
hosts) and supports live collaboration over the network.
