help me troubleshoot

[workroom]

Megadrum was working great until today. I firmware updated and now my hi hat isn't opening and closing at all. I double checked ground continuity with a meter, seems to be fine. I tried to check V DC across pin 40 and ground (15 or 16) but get nothing.

When I auto check level if nothing is plugged in it says 90, when i plug in the pedal it jumps to around 700 and doesn't change when the pedal is depressed.

I have a hall effect sensor in a box under the pedal and a magnet afixed to the pedal, like I said it was great until a few hours ago when i updated.

Tried two different computers, no change.

It was 4am when I posted last night and I spent 12 hours trying to get it working. Sorry I didn't provide enough information, and I didn't say please. Please help and thanks in advance!

I just tried real quick to connect the other pads and they're somehow connected to the hi hat problem. Because if I connect any pad while the hi hat is connected I get constant triggering that doesn't stop even if threshold is pushed to 127. Even when i try and boot while holding right.

And when I tried to load my old settings from mdm it appears fine until i restart md, loading fails.

At this point I am guessing that even though the firmware updated something must have gone wrong in the process.

Anyone help me think this through? About to reflash firmware, mac os, same computer as before. Maybe try the other mac too.

Reflashed, problem persists. Any help would be appreciated greatly.

Edit I have no idea where to look.

Hi,

Which firmware version did you load?

In the latest...Dmitri has done some changes to the hi-hat algorithm. So there are some new parameters...this also requires the latest MDM to see all fields.

If you load your old settings...and it works good...don't forget to save it into the first slot....otherwise it won't stay when you reboot.

Best Regards

0507 the latest.

I can hear my piezos ringing...

I disconnected hi hat pedal power and went through each pad setting the threshold at 60 retrigger at 1 and got some hi levels roughed in. Then i used a new cable for hi hat pedal, and reconnected it, and that's when I noticed the ringing.

And the pads all start triggering uncontrollably. It looks like voltage from hi hat pedal is bleeding all over the place?

You claim in your post that it works if you load your old settings?

If you are able to save your old settings to the MD (by using the function save to slot 1 in MDM) and if you set the parameter found on the MD Autoload=yes then the MD will load the working configuration when you restart the MD.


It is a bit hard to guess...the problems. Try to be more detailed in your post.

If it was working...why change all cables...etc?

Sorry I wasnt clear.

I didn't mean old settings work well. i just meant it looks like they load. I had forgotten to select autoload, true. I tried again and saved settings stick. But, old settings and newly created settings both malfunction.

I am going to try and give as much infomation as possible. Can take screen shots pictures or videos.

As soon as a plug goes into the pedal input all inputs begin triggering wildly. My guess is somehow voltage is going out the megadrum to the pads and i dont know what could make this happen. So, i thought i would try to skip the pedal for now and setup the other pads. But when more than one pad is connected they trigger each other. Like if i connect my whole kit and strike the snare, i hear (and see if i run midi monitor) )kick snare and cymbal simultaneously.

What have you got threshold(s) set at?

[workroom]

Even if i set thredholds all at 127

[angr77]

Make a screen shot of the hi hat settings and post it here.

What is your story? Have you built the MD yourself? ATMega or ARM?
Have you ever been able to use the MD?

Have you seen the cctringerin function? If you enable this checkbox and click send in the tab...you will see in MDM which drum who causes the most triggering. If you disable the cctriggerin at this stage...and click send. You are now able to go that epad that caused the error and raise the threshold or lower the gain. Continue with this process until all e-pads has stopped ringing. Most often when problems like this occur...there could be a cymbal switch or a rim/edge trigger that starts the error flow.

It is also important to have gone though the auto high level process for each drum. You have to actually turn auto high level to yes on the MD...jump to the next parameter eg. high level and hit the pad quite hard a couple of times....then you get the proper level for thar drum. Go back and turn auto high level off. Read or type it in manually for that drum from MDM...using load...if you want to reuse it.

For the hi-hat pedal...have you ever got it work? If so...have you kept the configuration?
If you disconnect the pedal...does the ringing stops then and you are able to play as usual on your drums? How has your HH input switch been set and do you use the alternative input...enabled in MDM?

Using a hall sensor is a bit different...I have no experience ... But it should maybe work. Can any other on the forum confirm?
