ThefourparametersonthispageareStart(S),AlternativeStart(A),Loop(L),andEnd(E).
Selectingthese
parametersandadjustingtheirvaluesenablesyoutomodifyhowthesample
playsbackwhennotesaretriggered.Eachoftheseparameterpointsareexpressedinindividual
samples.Forexample,aonesecondsampleatasamplerateof44,100Hzwouldhave44,100

TheStart(S)pointdeterminesthebeginningofthecurrentsample.Youcantruncatethe

IfyousettheAlternativeStartaftertheEnd,youcanextendtheplayofloopedsamples.
Normally,looped sampleswillplaythroughtotheEnd,thenwillloopbacktotheLooppoint,

IftheAlternativeStartissetaftertheEnd,loopedsampleswillloopinthesamewaywhilenotes

TheLoop(L)parameter

youtrytomoveitaftertheEnd,theEndwillmovewithit.Whenyou’ resettingaloopsegment
