One great way to do so without having to ask people for their contact information is through subscribing to your band where they consume music directly. For listening tendencies, this means encouraging them to subscribe on Spotify, YouTube, Apple, Amazon or whatever their favorite streaming site is. If they want to just know when they can see you live again, ask them to subscribe to your tour dates on BandsinTown or Songkick; whichever platform you use to post your shows.
Music creation software follows a few different interface metaphors: the multitrack mixing desk (Pro Tools), the rack of modular synths (Reason), the sheet of staff paper (Sibelius, Dorico, Noteflight). There are also hybrids of all of the above (Logic). Ableton Live is in a category by itself, because it’s organized around a kind of performable spreadsheet. Serato’s metaphor is two turntables, a crate of vinyl records, and a DJ mixer.
