Tech Crunch reports: “Spotify’s digital audio workstation (DAW) platform Soundtrap is introducing new features for musicians, including live collaboration, auto-save and comments. The firm said the first two features are under an opt-in beta so artists will have to manually enable these features. The company is rolling out the comments feature to all users starting today. This will allow people working on a project to leave notes on different parts of the track for remote collaborates.”
