Need help diagnosing possible hardware faults in MD
Posted: Mon Oct 19, 2015 5:03 pm
Well I have taken a few days off after more than 2 weeks of troubleshooting MD and read more of the forums and documentation. There has been much discussion about some issues in this thread
viewtopic.php?f=3&t=2626&start=20
but the scope has gone wider and Dmitri and I are in disagreement.
At first it appeared as though cold resetting the unit solved some of my issues but they have all come back.
1) Load Rom Map freezing, save config freezing occurs after some time. I reset, it no longer freezes then it starts freezing again after a few hours. Whilst in menus on the panel multiple VU bars (not moving) appear over the parameter text. After cold resetting hitting hhat on 2/3 lights up sensors 8/9. and I am aware of hh input settings or dual/triple head setting affecting sensor order. I have sifted through the forums and really tried to solve this assuming the unit is not faulty and its user error,
2) MDM sysex init and timeout errors frequently. I end up mainly using the panel now because of this. I have double checked USB leads, uninstalled copperlan, rtpMIDI virtual patchbays and gone direct from MD to PC/MDM with a short tested cable no other programs running. The unit will only hold green lights in MDM until I do a get-all or send-all or move a parameter to much as to apparently overflow the midi buffer (I have tried different buffer settings in MDM options), then a MIDI sysex timeout occurs followed by init errors. Only way out is to turn off MD, close all programs on PC, reset all midi drivers then reboot MD
3) Same settings for a 3zone cymbal that worked for a while no longer do now. After double checking manually and loading from file from when they did work. I cant get them to work anymore.
4) "AltEncoders" never stays off no matter how many times I switch it to no. Right hand encoder often cant toggle stably between yes and no, like it may be faulty but TBH I think its software related aswell.
5) I have powered it only from charger and used MIDI only. As soon as anything is plugged into the MIDI out it behaves strangely. I cannot use it as a simple midi device either.
6) MIDI light remains on, MD totally freezes requiring re-boot.
7) Intermittently turning on MD it will freeze on the copyright dialog.
8) In MDM pedal notes from bow semi open down to the bottom changes the wrong parameter in ipad commander, ie MDM"bow semi open" changes commander" "edge semi closed" and so on.
I am convinced there is something wrong with this unit. I have exhausted every possibility, with the assistance of a friend to keep my methods in check today. I really want to be able to use Megadrum in my studio Dmitri and I need your support as manufacturer. I feel like we are working against each other and I've never had this experience from a manufacturer before. I do know how to trouble shoot. I have a complex digital studio that I have built and maintained successfully for years. Should I make another video? What more do you want me to do? Why are you so reluctant to accept this could be a bad unit? Should we skype so you can see it live?
I guess I had to say this here on the forum before I go to PM with Dmitri because maybe someone else can help...? Has any of the above points happen to you?
I have truly tried, systematically, every possibility. I disagree with Dmitri's comment of it's "due to the wrong approach to configuration". After more than 2 weeks of trouble shooting MD I would not be randomly and manically going at it without a method. I'm often stopping and regrouping my thoughts, and step by step going thru a particular problem. It is just that the behavior is so hard to put my finger on, even Dmitri admitted that. His comment "I believe it is counterproductive to try address many things at the same time" is true in one context but it is ignoring that I have to describe a number of weird behaviors that are causing multiple problems.
One may ask what is it I want..simple
1) I want to use Megadrum (I dont give up easy), besides as I've said it has unique possibilities, I respect that.
2) I would like to return this unit and for it to be tested and another sent in its place if it is found to be faulty. I'd like to do this with the minimal amount of downtime because I have pressing sessions requiring edrums.
3) In fact what would be ideal is that - Dmitri sent me another tomorrow and I send this one back tomorrow or when the new one arrives. For that I would be grateful.
Thanks
