how do I turn on input monitoring in garage band
Tracks I can hear display a small 'button' labelled 'input monitoring'
Tracks I can't hear don't
Where do I go to enable this 'button'?
iMac, OS X Mavericks (10.9.5)
You enable it when you create the audio track,
If you do not enable it at that time, the audio tracks have an input monitoring button in the Smart Controls for the track, in the "Record Settings" in the Info panel.
