Transients of Millenium/Alesis Cymbals

[mprinz]

Hi guys, hi Rob!

does anyone of you use the Millenium/Alesis/Medeli cymbal pads and
notices those strange transients?

If yes, how do you set up the trigger?

It's a kind of blasphemic to use those devices on the eDrumIn ... but...sorry.

If no ... hm. I noticed it while playing the "China" and it results in not realistic sequences of velocities.
I think, its due to the highest peak being shifted back and forth. So increasing the scan time?
Of course this occures when hitting the cymbals several times in the same way and strength.

Thanks for your comments!

I would increase your scan time to 3ms and hold time to 5 ms. That'll certainly take care of the double triggering.

Ok. Thanks.
But its doesn't sound like double triggers. It sound more dynamic as it should because I hit the cymbal more or less with the same strengh. Maybe thats the difference to a 300€ Roland cymbal.

What s going on during the scan? Its scanning for the largest peak?
I am thinking of setting the scan time to higher values because the trash china will not be hitted faster that lets say 5 times per second. But this will be directly effect the latency... Hmmm

Or just hitting the edge, but the velo values are produced by the same piezo.... so.

Thanks for further comments.

Not much else to say. There were definitely double triggers going on on your video. Increasing the hold time does not affect latency, only increasing the scan time does. The way you have the scan time set in the video, you are sometimes missing the major peaks. When that happens, you get much lower velocity hits. That said, there do seem to be inconsistencies in the signal from that cymbal, but they are exaggerated due to poorly chosen scantime and hold settings.

Hi Rob,

I understand - "poorly chosen"
You're right! But I a have another cymbal, and it seems to be equally build but with more "exact" transients.
I checked the cable, different inputs.
Maybe its another piezo or whatever.
Should I tweak this with other piezos or places to stick or glues or do you think its ok setting larger scantimes to catch the main peak?

Thank you!

[Rob]

I'd say 2ms vs. 3ms is pretty insignificant.

[mprinz]

Sure, but sometime the largest peak is way later... Isn't it?

[perceval]

The largest peak should be the initial hit.
You have to set the parameters to scan out the vibrations that occurs after the hit.

If the vibrations are stronger than the initial hit, then I'd say it's a pretty poor design of an e-cymbal.

May someone who is using those Medeli, Alesis, Millenium MPS-400 cymbals can sent an printscreen of
the transients scanned by the edrumin? Maybe its a defect.

There's definitely at least one transient there that looks way off. Hard to really say what the issue is.
