Electronics is one of my areas of expertise...and as a Ham Radio operator (licensed radio station) with significant antenna systems I have studied and implemented lightning protection all too much.
Once, I had a direct hit on the antenna at 72 ft. to see that ball of fire come down the tower and crash the ground was something you can't imagine! None of my equipment was damaged...due to the protection I have installed. Even though a $400 Polyphaser protection module was blown off the side of the house on fire! (That's where all the antenna feedlines come in)

IMHO, My sugestions are:

1) Get a good quality power supply conditioner/surge surpressor, This is not one of those $20 units. One intended for a high end home theatre setup is perfect.

2) Leave the keyboard ON during any normal period of playing...whether it's a whole day, a gig, a morning..whatever. Do not turn it on/off every few minutes. In general it is better to leave electonics on all the time, but be practical.I never turn my computers at the house off (unless storms are coming)

3) If a storm is approaching UNPLUG the power surpressor (all you goodies should be plugged into it anyways) Do not just turn off the p[ower switch of the surpressor, unplug it. Hey,if your goning to be gone for a few days ect...just unplug it.

Ligtning is not forgiving.
