It's not very user friendly but anyway You will need to restart the project whenever you change the settings. A brief explanation of each: Scale: switch between major; natural, harmonic, and blues minor scales Tonic: change the starting pitch of the scale (60 is middle C) Octave range: change the range of notes played in each clef (right hand and left hand) Tempo: change the speed of the "music" PlayerR/L: volume: change the respective volume of the right and left hand notes Tell me if there's anything else you'd like to be customizable. ♪ I present you a project I did at 3 AM instead of my music theory homework :) Eula probably remembers a similar project from long ago. Somehow I didn't learn my lesson from that one that random notes on a scale sounds bad. ♪ By the way! I'd like to make another noteblock and I'm taking song requests for those. If you have a request, either name something I've been doing (Hamilton, Dancing Line, Sky :P) or give me a link to the song and sheet music I can use (i.e. from Musescore).
