High Level - strange phenomena SOLVED

[airflamesred]

Let me try to understand it once again.
1. With HiLevel set to 900 the maximum velocity you can get is 109 but this velocity is reached even with not very strong strong hits. Right?

Correct and all this is at a gain of 4. Changing the gain also had an influence.

2. This behavior is produced only with one particular pad/piezo, right?

I've tried 3 different pads

3. This behavior is the same no matter which input you plug this pad/piezo into, right?

3 different inputs

4. You have other pads which don't exhibit this behavior, right?

I don't think so but some of the pads only have a high level of 550

5. You tried to configure it starting with default settings and the result is the same, right?

What is default? The results I've shown above are very consistent.

I've only noticed this since adding this 35mm piezo as before, all the high levels where good at around 500.
Anyway, if you can't reproduce this then I'll sort something at my end (using smaller piezos or damping as Privatex mentioned)
@Ignotus
Am I understanding that you have a pad that outputs a maximum velocity of 80?

Default settings are loaded by MegaDrum on power up if AutoLoadConf is set to No.

I only have the one config but I can confirm that the various high levels that were sent did arrive

If I set the high level of that particular pad to 700 or 800, yes. It's not an exact value but what I mean is that unless I lower the high level to 400 - 500 it gets nowhere near a velocity of 127.

Sorry, I don't understand if you are answering my question or not.

Default settings are loaded by MegaDrum on power up if AutoLoadConf is set to No.

Did you reproduce the problem by starting from scratch, i.e. from default settings, or not? If you do it from MDM, start up MegaDrum with default settings (AutoLoadConf is No), pull config from MegaDrum to MDM and configure the input again. Is the problem still the there?

[airflamesred]

I'll have a look tomorrow but as I say I have 1 config and 1 matching mds. This is the first time I've opened MDM for months

But it doesn't mean that for the test/debugging you cannot start from scratch with default settings.
I just tested it myself starting from default settings with STM32F103RBT6 and STM32F205RCT6 boards and neither exhibits your problem.
I tested it with Pintech 10" mesh snare. With default Gain 4 AutoLevel detects HiLevel of 741 and I still get velocity 127 with hardest hits. I then raised Gain to 5 and with it AutoLevel detects HiLevel of 921 and again I can still get velocity 127 with hardest hits. I tested it with both default LogCustom1 and LinearCustom1.
You can also post you .mds config I will test with it.

Btw, I just noticed that 'Curve' labels on screenshots in viewtopic.php?p=28308#p28308 are all in blue which means that at least some curves, and possibly LinearCustom1, are not in sync between MegaDrum and MDM. It could very likely be the source of your problem.

So, Clearly the issue lies at my end and I consider that the end of the matter.
Thanks for testing.

I'm reviving this not because it's a problem but because I'm interested in the answer, If there is one.

So, as mentioned earlier 774 is the max high level I can set to achieve 127.
If I drop the gain to 3 (letting in less signal as I understand) it will output a max velocity of 107.
And so on til gain at 1 will only output max velocity of 89.

With gain at 1, to achieve a 127 velocity, I need to drop the high level to 631 which 'feels' about the same as 774/gain4.

MDS attached, thanks.
