Add ability to toggle drums, vocals etc from track
It would be great to customise tracks to toggle features such as drums, vocals etc. So I could use the app to play the song with others band members. For example I want play the guitar with guidance from Yousician and a drummer plays the drums rather than it on the backing track, but still have Yousician play the vocals and other instruments.
But make customisable so you can decide what you want to turn off and on.
Support for "muti-player" would be good, so multiple band members could run the app, but the song time-line is synced so everyone is playing in time.
