Hi
since adjusting the eq in my pa4x, I noticed some of the drums in my user styles are playing more loudly.

What I would have normally done is go into style edit , and adjust the velocity of the offending drums in the track. Pretty time consuming.

Something I've never bothered to explore before ( and just in case others haven't either is a function called Drum Edit.

Choose Style
Hi light Drum
Menu
Track Controls
Drum Edit

Just press play
Now you can adjust the volume of groups of drum types
Bass, Snares, Toms , hi hats cymbals etc

So if the snare drum in your style is too loud , turn down the volume.
Lot of other adjustments too.
( EQ too. Now I can really hear the difference it makes)
When you finish , just write to current style settings.

Possibly come in handy with some of those old korg legacy styles too.
