Intonation
Mostmodernwesternmusicuseswhatisknownasequaltemperament.Thismeansthatthe
intervalbetweeneachsemitoneofthe12‐toneoctaveispreciselythesameaseveryother
semitone.However,manydifferentintonationintervalshaveevolvedoverthecenturiesand
acrossculturesandinstruments,soequaltemperamentwill
notsoundappropriateforcertain
stylesofmusic.ThePC3LEsuppliesyouwith17differentfactoryintonationmapswhichare
usefulforarangeofdifferentstyles.Bychangingthevalueforthisparameter,youselectfrom
amongtheintonationmapsstoredinthePC3LE’smemory.Eachofthesemaps
definesdifferent
intervalsbetweeneachofthesemitonesinasingleoctave(usedforalloctaves)bysettingpitch
offsetsforeachnoteincents.
ScrollthroughthelistofIntonationmaps,andlistenforthedifferencesbetweensemitones.
Someoftheintervalsbetweensemitonesmaybequitedifferentfromequal
temperament,but
you’llnoticethatallnotesarepreciselytunedwithnotesthatareanoctaveapart.Thisisbecause
theintonationmapssettheintervalswithinasingleoctave,andapplythoseintervalstoeach
octave.
Likemanyinstrumentsbeforetheadaptationofequaltemperament,mostoftheseintonation
maps
weredesignedtosoundbestinonespecifickey.Thoughsomemayhavehistoricallybeen
inadifferentkey,allofthePC3LEsfactoryintonationmapsaresettorootnoteCbydefault.You
canchangetherootkeyofthecurrentintonationmapbyusingtheInt.Keyparameter(see
