Input Echo: Auto Thru

The help file says the options for the input echo button are On and Off, however my options are On and Auto Thru.  What is the difference between these two choices?

Yes, I am using Sonor VS. On the audio tracks, the options appear to be On & Off, while on instrument and midi tracks the options appear to be On & Thru.  I'm just trying to get a sense of what the functions of this button are.  Thanks much.

On & Auto Thru is only going to be relevent when you are tracking midi. To be really honest, I don't do a lot of midi and can't give a clear explanation of those. Maybe someone else that records a lot of midi can chime in. It means nothing when tracking Audio.

As for ON/OFF on audio, that I understand a lot more. With Input Monitoring ON - the audio you are recording will be directed back to the output so you can hear it. This is useful if you need to hear effects while tracking, or when your hardware doesn't allow you to monitor the input with the output.

However you have a VS-100. This allows you to monitor at the hardware level. Unless you really need to hear the effects added with Sonar, I would recommend you monitor directly through the VS-100. When I use my VS-100 I always turn input monitoring off.
