Members RobV Posted October 26, 2003 Members Share Posted October 26, 2003 Hey guys, I was just wondering if any of you guys that have owned a Rocktron Midimate controller ever had this problem. What's happening is, when I hit one of the buttons (could be any button) about 50% of the time it will either lock up completely, I'll get some garbage in the readout, or it will reset itself. Generally it'll just plain freak out on me. To remedy this I have to unplug the cable (I'm using phantom power) and plug it back in. Basically like a re-boot. I've taken it apart, and don't see anything broken or wires bare. Anything out of the ordinary. After I put it back together it was better for a while, now it's just as bad as ever. You could see how annoying this is when you're at a gig and right in the middle of a song it just freaks out like this. I'ts gotten to the point where I'm afraid to hit the buttons (not much good when that's what it's job is eh?). Let me know what I could do about this, or if you've had this happen. Thanks Rob Link to comment Share on other sites More sharing options...
Members EVH Wolfgang Posted October 28, 2003 Members Share Posted October 28, 2003 I've never heard of problems w/ that specific unit. You said that after taking it appart, it was working OK for a while. How long did that last? Link to comment Share on other sites More sharing options...
Members RobV Posted October 28, 2003 Author Members Share Posted October 28, 2003 It lasted for...hmmm... I'd say several days. That's the strange part. I really didn't do anything. Someone on another board suggested I take it apart and check for cold solder joints, and use some contact cleaner. I did this last night. I didn't see any bad soldering, loose components, or anything out of the ordinary. So I used some contact cleaner and cleaned both sides of the circut board. I guess I'll have to see if this improved it any. I'll get back if I see any lockups again. Just wish I would find something. Thanks Link to comment Share on other sites More sharing options...
Members EVH Wolfgang Posted October 28, 2003 Members Share Posted October 28, 2003 Well, I think that they mentioned good things to check for. Intermident problems are the worst things to troubleshoot. It's much easier if something dies completely, because you know for sure when you fixed it. Since it had a short period where it worked, I think it leads me to believe that there is a mechanical issue that is causeing an electrical problem. That would include the mentioned loose or poor solder connection or a frayed wire, etc. You should closely examine every inch of the circuit board. Use a magnifying glass if you got it. There might be a hair-line fracture of a circuit board. When it stopped working, did you move the board that day? Like, take it to a gig or another room or out of storage? The movement might have started or moved something into position to cause this problem. Link to comment Share on other sites More sharing options...
Members Simon la Grue Posted October 28, 2003 Members Share Posted October 28, 2003 Is it getting too hot, maybe overheating? Link to comment Share on other sites More sharing options...
Members RobV Posted October 28, 2003 Author Members Share Posted October 28, 2003 I highly doubt it. It's just a midi pedal with a small circut board. I don't think there is that much heat at all in it. Link to comment Share on other sites More sharing options...
Members sbrett Posted October 28, 2003 Members Share Posted October 28, 2003 I had the same problem with mine. I emailed Rocktron support and the guy said that perhaps the power supply wasn't providing enough output/current. The thing is that I was using the supply Rocktron gives with the midi mate. I finally just gave up on it and bought a behringer FB1010. Couldn't deal with the reliability, and if something goes wrong with the behringer I'm only out $100. I miss the readout on the midi mate though. Let me know if you figure out the problem. Link to comment Share on other sites More sharing options...
Members EVH Wolfgang Posted October 28, 2003 Members Share Posted October 28, 2003 Well, it's possible that the power levels the circuit board was seeing could still be low, even with a good power supply. You still have the socket you're plugging into, then all the interals of the pedalboard. It's possible that something inside was poorly connected or shorted, causing some of the power from the supply being diverted elsewhere and starving the circuit that needed it. The other thing is power supplies can go bad. Either there's an intermident connection and it get wiggled the right way or the power supply heats up enough to cause a hair-line fracture to expand, etc. I had a problem on my GC 1.0, where if I stepped on the board just the right way, the power connectoin wiggled enough to momentarily cut the power and reset the board. Start wiggling things and see if you can make the problem more repeatable Link to comment Share on other sites More sharing options...

Like from my basement, to the practice studio and such. Intermitent problems do suck for sure. I used it again last night for a while and it's still working OK. If it starts acting up again, I'll try the magnifying glass and examine the circut board closely ( I actually did, but without the magnifying glass). I'm really hoping that the contact cleaner did the trick Link to comment Share on other sites More sharing options...

You didn't mention that before. Did you do that when you first took it appart? Where did you spay. That may shed some light. Link to comment Share on other sites More sharing options...
Members RobV Posted October 29, 2003 Author Members Share Posted October 29, 2003 I thought I did mention it?? Whatever....The very first time I took it apart, I didn't use anything. Just put it back together, 'cause it looked fine. And it worked fine. This time after having trouble I cleaned the ENTIRE board with contact cleaner. It's now working fine again. For how long...who knows. Hopefully from now on:) Link to comment Share on other sites More sharing options...
