Great advice. However, it's just the snare that's too loud, not the cymbals, toms or bass. Striking them with similar technique produces a much louder sound from the supra than from any tom.
Then vary your technique! Do you know the exercise where you play (at the same time)
Right foot - bass
Right hand - ride
Left foot - hi hat
Left hand - snare
With a metronome, you play all parts, then cycle an accent through the limbs- first accent RH (ride), then RF, then LH, then LF. All the while, focus on the relative volume of each other part. It will help develop more control.
