  Scales with Scalemaker

// create a minor pentatonic scale over 2 octaves (9 notes), starting on F# in the
// 5th octave and get the value of the notes in hertz
// or 
// allScales === ['chromatic', 'wholeTone', 'major', 'majorPentatonic', 'minorPentatonic', 'kuomiPentatonic', 'chinesePentatonic', 'naturalMinor', 'harmonicMinor', 'melodicMinor', 'myWeirdScale'];

var myScaleInHertz = ScaleMaker.makeScale('majorPentatonic', 'F#3', 8).inHertz;
// console.log(myScaleInHertz)

const synth = new Tone.Synth().toDestination();

// Tonejs wants values in hertz
// make sure the arrays match in length
// try to use square brackets to add together multiple notes
// ['r', etc] will make it into a rest
const pitches = myScaleInHertz 
const durations = ['8n', '8n', '8n', '16n', '2n', '16n', '8n', '8n', '16n']
console.log(pitches.length === durations.length)
// combine them together 
const mergedData = toneRhythm.mergeMusicDataPart({
  rhythms: durations,
  notes: pitches

// see the data as an array of objects like Part needs
// console.log(mergedData)
const melodyPart = new Tone.Part((time, value) => {
  synth.triggerAttackRelease(value.note, value.duration, time);
}, mergedData).start(0);
melodyPart.loop = true
