Hotspot not detected

[Rob]

Ya, if the input is clipping with soft hits, then that's going to be the problem. Furthermore, if the input clips, the positional sensing will always set the position as center. You need to find a way to reduce the signal. You are using an ED4?

What you mean by clipping? Getting to 127?

Positional sensing seems to detect better than hotspot now but I'm concentrating hot spot first.


I have an ED10.

[Rob]

The ED10 has a lot more headroom than the ED4, so that's surprising. Can you attach a screenshot of your settings?

The hot spot is 0 but I tried all possible values hehe

[Rob]

How hard was that hit?

Start with the Amount control at 0 and first adjust the thresh control. After you have set the thresh control properly, start increasing the Amount control.

Rather unintuitively, if the amount control is set too high, the hotspot suppression will stop processing. I'll try to improve this behavior in version 1.3.2.

Not that hard.

I tried a lot of cone positions tonight again. Almost not touching to a lot. The amount at 0 help but not that much.

Still the threshold sense only when I it very sofly. If I hit normally near the center it spike at 127.

I even recalibrated hitting really really hard and it's still 127 near the middle. (at least 3po radius) even when the hot spot is detected (1/10 hits)

Ya, the signal is just way too hot and so it's clipping, and as a result the waveform that needs to be analyzed is missing information.

I don't know what else to tell you. You could use a softer come, a smaller piezo, or add a potentiometer to attenuate the signal.

Yes I'll tried one or all of those methods tomorrow and report back.

Thanks for the help.

I just did what Perceval talk about on vdrums forum.

I replaced the cone with a kind of cone I shaped in cheap tile grout sponge.

It's perfect, no hotspot. I don't even need the hotspot algorithm. The gain is way higher than before (in the middle) but it works. I think it's normal since it's less sensitive.

The only thing I didn't figure out yet is that it triggers rim clicks near the edge on the head but I can't adjust the rimshot range because it's register completely to the right. I think maybe the sponge is not enough touching the head so it's not touching or not enough decoupling. But it doesn't bother me that much for now.

[thenewdrummer]

Ok after more experiments the sponge is not better and it does the same issue.

So I bought a pot, set the value to the min, and put the gain not really high. So the transient doesn't become too hot and I can see all of it in the screen. (did different gain level too)

Tried another time different cone positions.

The HSS still doesn't show any threshold. I'm starting to be really discouraged. It's unplayable because in the middle it's always 127. I don't understand why it doesn't detect anything.
