ForoptimumresultswhenusingConsolewithoutaDAW,performsampleratechangeswithintheConsoleapplication(instead
ofwithinMacOSX'sAudioMIDISetupapplication).
ForoptimumresultswhenusingaDAW,performsampleratechangeswithintheDAWitself(insteadoftheConsoleapplication
orwithinMacOSX'sAudioMIDISetupapplication).
ForoptimumresultswhenApollo'scurrentsamplerateisdifferentfromthesampleratesetwithinaDAWsession,change
Apollo'ssampleratewithinConsoletomatchthesamplerateoftheDAWsessionbeforeloadingtheDAWsession.
UADResourceUsage
ApolloTwinusesDSPandmemoryforitsinternalDSPmixer.Therefore,theUADMeter&ControlPanelapplicationwillshow
someDSPandmemoryusageevenwhenUADpluginsarenotinuse.
UADPresets
Whenloggedintothecomputerunderanaccountthatdoesnothaveadministratorprivileges,savingUADpresetfilesviathe
UADToolbarwillresultinan"Unabletosavepresetfile"dialog.Ifthisoccurs,eitherloginwithanadministratoraccount,oruse
theDAW'spresetmanagementtools.
WhatisthelowesthardwarebuffersettingIcanusewithApolloTwinforstableoperation?
TheaudiointerfacehardwareI/OportionofApolloTwincanrunatanyhardwarebuffersettingthatisstablewithintheDAWitself.
ResultsmayvaryasaresultofhowmuchtheDAWsessionstressesthecomputersystem.Thiscanbeinfluencedby:
Sessiontrackcountandsamplerate
Howmanyprocessorintensivenativeplugins(suchasvirtualinstruments,convolutionreverbs,etc.)areinthesession
Processortype,speed,andoverallpowerofthecomputer
Ofcourse,forthelowestpossiblelatencywhenmonitoringliveinputs,werecommendusingtheincludedConsoleapplicationto
takeadvantageofApolloTwin’suniqueRealtimeUADProcessingfeature,whereDAWI/Obufferingdoesnotapplyatall.
SystemSleep
SystemsleepiscompatiblewiththelatestApolloTwinsoftware.However,disablingsleepwhenusingDAWsoftwareisgenerally
recommended.ForoptimumresultswhenusingApolloTwinwithDAWsoftware,followtheseguidelines:
Disablesleep.OpentheEnergySaverpanelwithinSystemPreferences*anddragthe“ComputerSleep”slider(ifpresent)to
“Never”(thefarrightposition).
Beforesleepingthesystem,quitanyDAWsoftwareusingUADplugins.
IfUAD2SatelliteFireWireisconnected,systemsleepMUSTbedisabled.SleepisnotcompatiblewithUADFireWiredevices
(UAD2SatelliteThunderboltiscompatiblewithsystemsleep).
*ToaccessSystemPreferences,clicktheAppleiconintheOSXMenuBar(upperleftofscreen)thenselecttheapplication
fromthedropmenu.
