So you are using Neural as an inserted plugin on the guitar channel in PT, yeah? And you're still hearing the direct clean sound when you play, but not when you playback what you've recorded?

Do you hear the clean sound through your UA even without arming the track in PT? If so, you may have "direct monitoring" switched on. Run your UA app "Console" to check for that.

This can also happen if your hardware responds to selecting low-latency monitoring in PT - but I don't know if the Apollo does.

Latency may be an issue with Neural once you get that DI sound muted... If so, you could look into using an onboard amp sim in the Apollo (even for monitoring only while still recording through the Neural in PT) because it has its own processors for plugs to help reduce latency. You'll need to experiment...
