  1. Greetings, I have been using seq v4 since a year without problems. Suddenly today this error message pops up saying "MIDIProtocol Timed Out!!!" In addition to that, on midi I/O board, OUTB Led is constantly lit, while it's not configured to do anything. No problems on OUTA however. Midi in is not working, seq v4 does not receive any midi clock unless it's from usb. When I monitor OUTB, it is transmitting a C-1 note off message very rapidly, perhaps choking the system. Tried the following: I swapped chips on midi I/O and front panel Reflashed bootloader and firmware. Checked for corrosion, bad joints etc. Thanks!
  2. Hello! I ran into peculiar problem with my good old Sammich and can´t figure out what might be the problem. Any tips are more than welcome :) I built the thing myself about 6 years ago. It has worked fine for a long time but after a small break i noticed this: Left output functions OK. RIght output is completely dead. I swapped the SID chips to see if it was the chip but the problem remained the same i.e. sound comes from left but not from right. So the SID chips seems OK. Then i swapped the M74.. IC´s below the SIDs but no change in the issue. So I tried to probe-listen directly from the SID audio out pin and the left SID sounds ok and right one gives some quiet hiss/crackle (not completely dead as in the audio output though, but also not noticeable notes). In other words both SID chips works just correctly but not when installed to the right side/right output. Been trying to search for bad soldering (well, i´m not too pro but still haven´t found any actualy mistakes or cold joints) but i´m wondering what the heck might cause this problem? I have a couple of different wallwarts with appropriate specs, and as I mentioned, this thing has worked before for some years... Thanks!! :)
  3. Wondering if anyone else has had the same issue I am having right now, or if any one knows how to solve this issue? I was playing around with my MB-6582, and of course I have to mess with every option available. I came across the DOR (Disable Oscillator Reset) option and decided to give it a try to see if there was a noticeable difference when switching patches, which I didn't so I turned it back off. I didn't immediately notice any changes or problems. I turned off my synth and when I turned it back on I noticed that I could first off not hear the Mios startup jingle. After that I was not hearing any sound from my initial patch (Pulse wave on Oscillator 1 for L&R). I checked my DAW and saw that there was audio signal going to the channel, the patch was just playing at a very low volume. I tried to adjust the volume from the CTRL panel and this did not change the volume any louder. At this point I started troubleshooting my cables, my audio interface, my monitors and concluded that the issue was with the MB-6582. I tried different patches and when I got to the ones that throw out a relatively high signal I had full volume of those presets. So I decided to test any idea. I switched back to the initial patch and started messing with the oscillators. It wasn't until I used the Detune function past 4 that the regular volume of the patch returned. I tried this on other patches that were have the same issue and it was consistent. Every time a switched to a new preset I had to for most of them use the Detune to bring back the expected volume. I turned the DOR back on and found a loud preset and then as I switched presets they all had their volume back. Is there a reason why activating the DOR and then turning back off would cause this issue? Additional troubleshooting I performed was restarting the MB6582 multiple times,reinstalling MIOS and MBSID, even tried deleteing ensembles in case I accidentally save something in there. Any help or insight would be greatly appreciated. Thanks!
  4. So sorry to be a burden to the group....it seems I got over excited with my updating and probably did something stupid. I downloaded the latest firmware v4,086 and started up MIOS Studio 2.4.6 everything seemed as I had left it and it discovered my Midibox via my cheap Chinese style usb to midi in/out cable no problem. here is where I THINK I went wrong... I had the options of folders MBHP_CORE_LPC17 MBHP_CORE_STM32 MBHP_CORE_STM32F4 I chose STM32F4 (I now suspect wrongly) MIOS let me upload just fine and I did get the ...success...message at the end of the upload. I then turned my MIDIBOX SEQ V4 off and on again...only to be greeted with black squares on the display...nothing else. no amount of waiting around will yield it doing anything else and now it won't seem to connect via my USB to din cable at all... I took a look through the trouble shooting guide but I am not seeing my usage case. please help if you can, I am really worried I have killed my box. thanks Phill
