velocity correction using positional sensing

[DavidCourant]

Hello all,

I don't yet own a edrumin module, so I was wondering the following.
I have a center trigger in my snare, so offcenter hits have significantly less velocity than hits directly at the center when hit with the same force. Since edrumin "knows" where the drum is hit (if I understand correctly), is there a function within edrumin that lets you add say 10% velocity for example when edrumin notices an offcenter hit to correct this undesirable behavior of center triggers?

No, that functionality is not implemented.

... however ...

hotspot suppression (which is what you're trying to achieve) works well

[DavidCourant]

I don't have a problem with hotspots.
My problem is that the velocity is uneven across the drum when hit with constant strength. So it would be nice to have an electronic correction for that unevenness.

Hi,

but these are interesting thoughts, I correct the "feeling" for the three zones in SD3 but since I have to do this
for every library It would be nice to have 3 independent velocity curves for 3 ranges of CC16. Or not curves just scale factors.

While technically not a problem for sure, there will be some problems like space in the GUI, memory etc. I guess.

[DavidCourant]

I think it could be done in GUI by just entering a number (e.g. 10%) as the maximum velocity boost (when hit far offcenter) and the actual boost is then linearly scaled.

I have never been able to get Hotspot Suppression working properly on any my triggers. On some drums it just doesn't work at all, and on others, it kills the dynamic range entirely. This is with Roland triggers as well as my DIY snare. I understand that it works great for others, so I just shrug and move on. However, what I did on my snare, with Positional Sensing enabled (which *does* work great), is simply change the volumes of the different articulations in SD3 (i.e. make the Center less loud than Off Center and Edge, respectively.)

[mprinz]

Oh... this actually a useful advice.
Because, as I said, I adjust the velocity mapping for the non-center sounds and I missed the possibility to also adjust the volumes.
But... monospace, is it the same for you, that you can hardly trigger high velocities for the edge sound?

That's a hotspot...

That's not my definition of hotspot.
Hotsopt occures only when you hit the pad just above the head sensor (in a zone of about 2cm wide). It can be greatly reduce by tightening the head. The more the head is tighten the smaller the hot spot zone is.

I feel quite natural to have less volume on the edge of the drum pad. I think it's the same on an acoustic snare drum.
