Convert a MIDI note number to frequency Performs MIDI-note-number to frequency conversion. Frequency is reported in as a float in Hertz (Hz). Cycling '74 Max math MIDI TEXT_HERE TEXT_HERE MIDI note number input MIDI note number input frequency output TEXT_HERE TEXT_HERE MIDI note number Outputs the frequency for the incoming MIDI note value (0 - 127). MIDI note number Outputs the frequency for the incoming MIDI note value (0 - 127). List of MIDI note numbers Generates a list of frequency values corresponding to the list of MIDI note numbers. Set the base frequency Sets the "base frequency" used when calculating frequency values (e.g., A = 440.). The default base frequency is 440 Hz. Keyboard Map A set of values, given as a list, for a keyboard map in Scala format:

• Size of map; the pattern repeats every so many keys (example: 12)
• First MIDI note number to retune (example: 0)
• Last MIDI note number to retune (example: 127)
• Middle note where the first entry of the mapping is mapped to (example: 60)
• Reference note for which frequency is given (example: 69)
• Frequency for reference note, as a float (example: 440.0)
• Frequency for reference note, as a float (example: 440.0)
• Scale degree to consider as formal octave, determines difference in pitch between adjacent mapping patterns (example: 12)
• Mapping (example: 0 1 2 3 4 5 6 7 8 9 10 11)

Note: to indicate an unmapped key, you can use either an "x" or "-1". At the end of the list, unmapped keys may be left out. For more information about keyboard mappings, visit the Scala documentation. Keyboard Map File The name of a valid keyboard map file in Scala format that has been saved in Max's search path will cause mtof to use that mapping. The file extension (.kbm) can be omitted. For more information about keyboard mappings, visit the Scala documentation. Middle Note Number The note number where a Scala scale begins (default 60). Reference Note Number The MIDI note number assigned to the base frequency (default 69). Scale Data A set of values, given as a list, for a scale described using the Scala format. The first value is the count of notes, followed either by floats defining a value in cents (example: 579.47057) or a ratio of two ints (example: 5/4). For more information, see the the Scala documentation. Scale Name A valid scale name from the Scala archive , will cause mtof to use the tuning described in that scale for its MIDI to frequency conversion. For this purposes of this attribute, the file extension (.scl) can be omitted. The frequency corresponding to the received MIDI pitch value.
