Getting good levels and panning

Hi loving this so far.. We’re lucky enough to all have good wifi and live within 5 miles of eachother so we can rehearse with <20ms latency so life changer for us..
However biggest problem for us is being able to get a loud enough mix – our local instruments are drowning out the remote instruments. Would be great to have the ability to boost the remove signal.
The remote signal is also panned to one side, this happens for both parties so we only get the other player in one ear. It seems like we’ve achieved the biggest hurdle of latency but can’t quite rehearse successfully due to these small details..
Thanks you for all your efforts with this service
