They can also be used to play notes which are usually unplayable such as overlapping notes or notes which are blocked by Bedrock. They can only play piano, drum, bass, sax, flute, spanish guitar, and violin notes and sheets such as Sheet Music: Spooky and Sheet Music: Winterfest cannot be played.
The volume can also be adjusted, however, the sound can only be softened. The maximum volume is 100 which is the same as a regular sheet music. It can be reduced by changing the value to less than 100.
A single Audio Rack can play up to 5 notes at once. Notes can be added by entering a series of music notes into the textbox after interacting with the block with a wrench. Each "music note" entered into the Audio Rack has three parts, the instrument, the note, and the accidental, entered in that order. The note is any letter A through G, with lowercase being the lower octave and uppercase being the higher octave. The options for accidentals and instrument names are listed below.
The letter for each playable instrument:
- 'P' - Piano
- 'B' - Bass
- 'S' - Sax
- 'F' - Flute
- 'G' - Guitar
- 'V' - Violin
- 'D' - Drums
The letter for each accidental:
- '#' - Sharp
- '-' - Natural
- 'b' - Flat
