SLP Posted June 30, 2008 Report Share Posted June 30, 2008 Hi folks,my MB_SID was working very well for about a month. And just one hour ago I wanted to try JSynthLib to control my MB_SID. I made some random changes (OSC, ENV,etc) and pushed the "Send" button.After that my SID started to make some kind of Square wave with a frequency of 2 or 3 Hz. Basically It was just some regular "popping" sound.I switched my SID on and off, and when I played some of my patches, it made some distorted sounds, the filter went crazy (though it wasn't assigned to any channel), and the sound didn't stop when I released the key.So I uploaded MIOS and then the SIDV2 app, and it was still the same.I switched the SID with a new one from Wilba, and it was still the sameI even switched the PIC...and it was still producing some weird distorting sound.I'll recheck everything tomorrow...but I'm still wondering: Can a SID-chip be destroyed via software (Syx dump) ?matthiasedit:I've just tested it again with the initial patches, and it sounds different depending on the engine:Ld: key pressed: sound (as usual, just a bit quieter) key deperessed: sound keeps going (probably other Pulsewidth, just as loud as when the key is pressed)Ml: just distorted, seems that the first instrument does not always work. the sound stops when the keys are releasedBs: works, but really quietDr: some work, some don't, some keep repeating even when the key is released, distorted@mods: feel free to move to the troubleshooting section... I wasn't quite sure where to put it. Quote Link to comment Share on other sites More sharing options...
stryd_one Posted July 1, 2008 Report Share Posted July 1, 2008 I wonder....was this the first time you sent sysex to the device?The problem sounds like hardware, I can't help but feel that maybe the whole sysex/JSL thing is just a coincidence.... or maybe it somehow triggered a short, that broke something else...Is it the same sound on all the SIDs? Have you tried new opamps? Quote Link to comment Share on other sites More sharing options...
SLP Posted July 1, 2008 Author Report Share Posted July 1, 2008 I wonder....was this the first time you sent sysex to the device?yep.Is it the same sound on all the SIDs? yep.Have you tried new opamps?I guess you mean the transistor.nope.but I'll try that....and I'll record some sound... 'cause that's a really strange one.. Quote Link to comment Share on other sites More sharing options...
SLP Posted July 1, 2008 Author Report Share Posted July 1, 2008 dumb dumb dumb dumb...I used another PSU this time... and it was just a bit to weak.I didn't notice it the first time, because the Ld init patch sounded just a bit different.The JSL thing was coincidence.Now swapped to my old PSU.Now 13W@12V instead of 12W@12V.dumb dumb dumb dumb dumb dumb dumb ...
