well,im no expert but,what i can say is,
it would be better if you could learn from experience drummers on how to tune it the good old-fashion way.This is because you wouldnt want to be relying on a device to tune drums forever.In addition to that,tunning allows you,the drummer to give it that precise tweaking to make it sound just like you want it,jit just adds that alittle bit of sweetness to the sound u want.
just my 2 cents
