Hi Tony,

Band-in-a-Box doesn't provide input monitoring (this is handled by your audio interface), so this can't be done, sorry.

RealBand can do it though. You'll have to be using an ASIO audio driver (or WAS if you're using 2018), and have "Enable Input Monitoring" checked in the Audio tab of Preferences.

Then in the DirectX/VST Window, choose "Input Monitor Insert" in the Track drop-down menu, and any plugins you select will be heard in your headphones or speakers while you record.

Thanks
Kent
