Class Utils

Converts velocity to value 0-127

Gets what to multiple ticks/quarter note by to get the specified duration. Note: type=='note' defaults to quarter note, type==='rest' defaults to 0

Returns the correct MIDI number for the specified pitch. Uses Tonal Midi - https://github.com/danigb/tonal/tree/master/packages/midi

Due to low precision of MIDI, we need to keep track of rounding errors in deltas. This function will calculate the rounding error for a given duration.

Static

Due to rounding errors in JavaScript engines, it's safe to round when we're very close to the actual tick number

Static

Gets the total number of ticks of a specified duration. Note: type=='note' defaults to quarter note, type==='rest' defaults to 0

Checks if argument is a valid number.

Get an int from an array of bytes.

Takes a number and splits it up into an array of bytes. Can be padded by passing a number to bytesNeeded

Translates number of ticks to MIDI timestamp format, returning an array of hex strings with the time values. Midi has a very particular time to express time, take a good look at the spec before ever touching this function. Thanks to https://github.com/sergi/jsmidi

Counts number of bytes in string

Convert a string to an array of bytes

Converts value to array if needed.

Gets MidiWriterJS version number.
