Not sure what you are asking for here, the GLD recording is at 48Khz 24bit. I record multi track using a Dante card on a regular basis, and 2 track to USB.
If you are saying you want only 16 bit just down convert on mixdown.
As for the ip8 is designed for drive and it talks a different language, but if remote control is what you want the iPad app works great, and you can create custom layouts, also One Mix for giving musicians control over their mix while not giving them access to everything.
If a unique mix is what you are looking for the ME1 is great, all our musicians use them for IEMs.
