A9‐3.Checkifrecordingsoftware
(notsuppliedwithGT40)recognizestheGT40asthedefaultrecordingdevice
※ RecordingsoftwareisrequiredtorecordusingtheGT40.Furutechrecomme ndsfree‐to‐download

A9‐4.ChecktoseeifbothInputandOutputsettingsintheSoundorMIDIapplicationarenotsetto24bit/96KHz
TheTENORchipusedintheGT40hasabandwidthlimitationof12Mbps(USB2.0fullspeedoperation),and
duetothislimitationonly oneI2Sinputoroutput
canbesetfor24bit/96KHzapplicationatonetime.
Therefore,underthiscondition,forsimultaneousmultiple‐channelapplicationsotherI2Sinterfacesmust
beconfiguredat16‐bit/48KHzor16‐bit/96KHz.Inotherwords,whenrecordingitisnecessarytosetthe
audioInputonthecomputerto24bit/96KHz(PC‐Sound
application;MAC‐MIDIapplication),butdonotset
nottheaudioOutputto24bit/96KHz.TheOutputshouldbesettoalower16bitresolutionuntilrecording
isdone.Thenwhenyouwanttoplaybackyour24bit/96KHzfilesthroughtheGT40youneedtoresetthe
outputto24bit/96KHzandresetthe
inputtoa16bitresolution.
