There seems to be a small copy/paste error in the PDF: both additional MIDI ports are numbered #3, whereas I think one of those should be #4? Which one?

Just checked with Reichelt, they don't seem to have that model, but the TSR-1 series from Traco Power seems to be equivalent (not sure about the noise, though). And it is only 8,80 Euros, which is rather cheap if you consider the savings for a single voltage (12V) power supply.

What OS are you on? The M-Audio Uno is known to work with Win XP 32bit. It may have problems with other Operating Systems? Another thing to check: have you connected MIDI Out of your M-Audio with MIDI In of your core? And MIDI In of the M-Audio with MIDI Out of the core? Only then will you transfer data!

Yes, I totally agree with that!

If you have the heatshrink in place, the croco clip will destroy it when heating up. Either way, you don't want the heat you put into the solder joint to dissipate! You heat it up for a purpose, by adding the croco clip as heat spreader you increase the risk of ending up with a cold solder joint.

Have you soldered the headers to the PCB already? You should notice that the wires easily come off again in the process, because of the heat you apply to the header/PCB joint.

Just a suggestion here: do not edit old posts except for adding a 'solved' to the title, because only then others can find the thread when doing a search and learn from your problem and solution. Open a new thread for a new problem.

You do realize that the SwinSID is a replacement for the SID chip, right? That means if you can control a SID chip with a MIDIbox SID, so can you control a SwinSID. Whether the SwinSID physically fits into the sockets of an MB-6582 board is a different question, though.

Look again, it's here. Just scroll to the paragraph that is titled "The Costs", you'll find all the info there.

I don't believe this has been the case - you probably got lucky and received gold plated pads because someone payed the extra on your panel. So far, all my orders had this feature, but Laen won't give any guarantee that this is the case everytime.

I can wholeheartedly recommend Laen's excellent PCB service. You need to order in multiples of 3, but even really small boards are no problem. Quality is stellar, and pricing is more than good. And the boards are purple :purple: Best, ilmenator

Hi johnc, I don't want to sound disrespectful, but you could answer all your questions yourself (except no. 3 maybe) by simply trying out what you suggest, and report here! :thumbsup: Best, ilmenator

Are you sure that the d8b is using MIDI controller data internally? If so, do you have access to the physical MIDI connection inside the d8b (I wonder if there is any, though - could be a virtual MIDI port as well)?

The thread you link to provides sound demos for different filter caps on a 6582. You say you have 6581s, so you'll have to check which are the standard caps for this chip. I would interpret the sentence you quote in the way that the 22nF belong to 6582s, whereas 470pF go with 6581s.

Yes!

Have you done the same for the button holes?

Those are projects not supported any longer. I'd recommend you look at the GM5, an excellent MIDI interface.

Your MIDI interface is known to be unreliable for SysEx transfers. Look at the whitelist to find one that is known to work.

This sounds like you should re-solder all solder joints on that PCB - heat up every single one, you may have broken some mechanically when fitting the board to the frontpanel. Edit: just saw that you have one single PCB underneath that frontpanel - so it's a big task to re-solder every joint... :rolleyes: Of course, look at those that are related to buttons that don't work!

Same but cheaper: ebay item number 290621132853 - I just ordered one, hopefully there is documentation for the pinout of the header...

Gut, die Beduerfnisse sind ja unterschiedlich, deshalb sollte ich nicht an Sinnhaftigkeit zweifeln :-) - sorry. MB64 ist die richtige Basis fuer das was du vorhast. Mein Hinweis zu alternativen Sequenzern galt dem SEQ V4 Projekt, vielleicht schaust du dir das doch auch mal an! Gruesse, ilmenator

Aehem, ja. Also warum willst du einen Doepfer Stepsequenzer modifizieren, wenn du fuer weniger Aufwand einen kompletten Stepsequenzer haben kannst, der das Doepfer-Teil locker an die Wand spielt? Interface oder Firmware? Was genau willst du tun? Den Doepfer fernsteuern? Dazu waere vielleicht ein MB64 Projekt geeignet? Trotzdem zweifele ich sehr stark an der Sinnhaftigkeit dieses Unterfangens... :no: Gruesse, ilmenator

I know it sounds lame, but my logic analyzer - another DIY project - broke down. Now I have two issues to solve. It's not forgotten!

This thing looks HUGE on photo while I know it's so tiny...
