Describe note

note

[note (symbol_or_number)]

Takes a midi note, a symbol (e.g. :C ) or a string (e.g. 'C' ) and resolves it to a midi note. You can also pass an optional :octave parameter to get the midi note for a given octave. Please note - :octave param is overridden if octave is specified in a symbol i.e. :c3

Introduced in v2.0.0

Example 0 


# These all return 60 which is the midi number for middle C (octave 4)
puts note(60)
puts note(:C)
puts note(:C4)
puts note('C')


 
 
 
 
 
 



Example 1 


# returns 60 - octave param has no effect if we pass in a number
puts note(60, octave: 2)

# These all return 36 which is the midi number for C2 (two octaves below middle C)
puts note(:C, octave: 2)
puts note(:C4, octave: 2)
puts note('C', octave: 2)


 
 
 
 
 
 
 # note the octave param overrides any octaves specified in a symbol
