Hi Hat Openness Transitions in E-Drum Optimized mode with a slow close

[pumpkinking]

Hi Folks – was having an issue with hi hat dynamics that took a while to root cause.  Maybe it is by design, but seems like could be a bug so I’m detailing here.

The issue was that in some instances a “hit then close” or “hit while closing” on the physical hi hat (Lemon stand hi hat going though eDrumIn module with pedal in CC mode) would not transition to the close articulation (in various libs that I did not make a note of but definitely SD3 Core which is where I finally debugged).  It was randomly affecting me while I was playing, but I finally was able to reproduce it 100% of the time with a “slow close” of the pedal (meaning hit once while open and then close the pedal slowly over a second or two).  In my case it was not transitioning to the close articulation sound.  If I closed quickly it would almost all of the time (but not every time).

After checking the midi notes coming into SD3 through the eDrumIn (which were correct and as expected), I finally found the Openness Transition setting in the Midi/EDrum settings page, which I had set to “E–Drum Optimized”.  I toggled that back to “Library Default” and everything worked as expected.  So I’m good now, but this was a big time sink to debug.

So my question is: is this behavior expected?  By reading the description of E-Drum Optimized, it would seem to imply a realistic experience for E-drummers.  My experience did not match that expectation.  Hoping this is just a bug.

Thanks!

You are correct that library default is a more realistic behaviour but a problem that some users experienced was that when hitting the hi-hat pad, especially a moving hi-hat pad, a change in CC value would occur that caused a transmute into the next more closed layer before returning to the former position causing another transmute.

The ‘E-drum optimized’ setting stops this behaviour by disabling the transmuting on pedal movement only when closing the hats. The hi-hats continue to transmute when moving the pedal to a more open position.

eDrumIn also has it’s own “SteadyHats” feature which aims to alleviate the issue Damian describes and IMO does a much better job than SD3’s solution.  I’d guess they wouldn’t play nice having both on at the same time either, but from memory of brief testing I much preferred the eDrumIn solution.

Betting it being improved for SD4 will be one of it’s bigger selling points.

Cheers.
