Convert frequency to a MIDI note number ftom converts frequency to MIDI note numbers Cycling '74 Max math MIDI TEXT_HERE TEXT_HERE Frequency In TEXT_HERE TEXT_HERE MIDI Note Number Out TEXT_HERE Float output If a float value is present, the ftom object outputs floating-point values with fractional parts. By default, it outputs whole number values. Convert frequency to MIDI note number Outputs the MIDI note number (from 0 to 127) corresponding to the frequency Convert frequency to MIDI note number Outputs the MIDI note number (from 0 to 127) corresponding to the frequency Convert frequencies to MIDI note numbers Outputs a list of MIDI note numbers (from 0 to 127) corresponding to the frequencies in the input list Base frequency Sets the "base frequency" used when converting frequency values (e.g., A = 440.). The default is 440. Keyboard Map A set of values 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 ftom 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). Round Output When round is non-zero, ftom outputs the closest whole MIDI note number value for the frequency it receives. Otherwise if in float mode, ftom outputs a number with a fractional part corresponding to the distance between the two closest MIDI note numbers. If ftom is in int output mode, it outputs the MIDI note number at or below the input frequency value. Example: in int mode with other attributes at their default values, 439 would output 69 when round is enabled and 68 when round disabled. 439 is closest to 440 Hz (MIDI note number 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 Scala documentation. Scale Name A valid scale name from the Scala archive , will cause ftom to use the tuning described in that scale for its frequency to MIDI conversion. For this purposes of this attribute, the file extension (.scl) can be omitted. The MIDI note number that corresponds to the input frequency. When an input frequency falls between two equal tempered pitches, the value is rounded to the nearest int when ftom is used in its default int mode. When ftom is used in the optional float mode, the fractional part of the float is included, which could be used to calculate an additional pitch offset for applying MIDI pitch bend.
