A speedy recovery, Scott.
One thing I tried doing while my hand was immobilized was using Pianostyle Mode with just the one hand (my RH). Full kbd chord recognition, etc., then just chord where needed, and solo over it. It's a really good exercise to train your hand(s) to solo with only one or two notes tops, so you don't trigger another chord accidentally.
Another trick is to set the sound up so that it ignores the first 20-30 velocity levels.... Whatever your arranger needs in order to allow you to solo but play softly on the chord part and it ignores it. Now you can do the same trick with non-comping sounds like sax etc..
Get well soon...
