I was asked whether the buttons would align with Wilba's MB-SEQ frontpanel design - the answer is no, and the reason you can see below. In my panel, there will a TPC and step display and a BPM display to the left of the button / Duo-LED matrix. A second reason is that the protoboard manufacturer I used has a size limit that I had to follow. Also, I was asked about how the buttons would sit in the frontpanel. I am using 8mm spacers and 3mm thick front panel, and the caps are flush with the surface, the round part sticking out slightly. It's perfect for sliding over a complete column of buttons (or row, but that would make less sense I guess).

Have you tried to slave it to other software than Ableton? Does it show the same behaviour then? If not, it might be Ableton that is at fault here?

Ich zitiere mal http://ucapps.de/midio128.html: Mit anderen Worten: ja, das geht. Schau dir mal die MIOS Studio Seite an, wenn du da zum Eintrag "MIDIO128 Tool" runterscrollst kannst du erkennen, welche Konfigurationsmoeglichkeiten du fuer Taster und LEDs hast (ohne dass du Code programmieren muesstest). Noch besser: lad dir MIOS Studio einfach runter und probier es aus, Trockenuebungen kannst du auch ohne angeschlossene MIDIbox machen!

Hey rony, ever thought of building this yourself? It's easier than you probably think, and it will make you proud of yourself. After all, this is a DIY place and people here are generally very helpful. Because we've seen this many times before, just a simple word of warning: if you are interested in MIDIbox projects because you think you will end up cheaper than with a commercial solution (in your case e.g. a second-hand Tascam controller), you might have to re-think. Whereas the components might be cheap, things like large printed circuit boards in low quantities and a proper case/housing for the unit can become rather expensive. Good luck, ilmenator

Not yet, as I have to decide what to make available (the Gerbers or the KICAD sources or both). I have three spare boards that I'd be willing to sell for 30 Euros each - this is what I paid for them as prototype boards. I also have two sets of Marquardt switches, desoldered from some video editing equipment that was hardly ever used. (Same as those you see on my board). PM me if interested.

Today I have finished a (traditional) BLM 16x4 board and have confirmed it to be working. It uses duo LEDs and the very nice Marquardt 6245 series of buttons. Together with Wilba's MB-SEQ Control Surface and a TPC / BPM module it will fill the upper half of an abandoned Roland MV-8000 case. The board holds all necessary components including surface mount shift registers (DOUT and DIN) on the backside and connects via a single 10pin cable to J2 on Wilba's control surface board. Additional modules (BPM and TPC displays) can be connected to a second 10pin connector that loops through all serial I/O signals from J8/J9 of the Core32 board. Here are some images: I am really happy that the "old" BLM code is still available in V4, and that it is supported in the config file - thanks TK! Best, ilmenator

Mine arrived in Norway today - thank you very much, sir!

Double posts are not encouraged, they clutter the forum...

I'm not TK but I can say that reading just a part will more often than not get you things in the wrong way. So, no, it is not stopped, in fact most of it is already there.

You could try Bome's MIDItranslator to convert MIDI commands into PC keyboard strokes.

A panel depends on use-case - some might want a display to go with the encoders, some may not. Modular panels are not as appealing as single-piece ones because they look less professional. Putting a set of encoders into a rack is probably not what most people will find useful, at least not in terms of ergonomics - you'd rather operate encoders on the flat surface of a desktop-case instead. Also, I don't think a universally good panel exists. Instead, Ponoko is a very good, cheap and reliable source for individualized panels, and with the panel files available even my grandma can order such a panel (for one, two, three or more encoder PCBs) from there. In general, for DIY it is a very good idea to take one step at a time, especially for people new to MIDIbox. I am sure most people ordering the PCBs now do not even know what to do with them yet, and I do not even exclude myself from that...

No, these boards are made for (endless) rotary encoders. Analog pots require different boards (and different software).

What MIDI interface are you using? Check the ones blacklisted here, these are known to fail for SysEx data transfers.

Ok, move only one pot (tell us which!) from minimum to maximum position, and nothing else. Maybe we can see a pattern then.

Sorry but you must try to be a bit more concise here - which pot have you moved for getting these messages? All of them? How much? Anyways, it rather looks like some of your analogue inputs are floating. Make sure all inputs are connected to pots, or if not that they are connected to ground.

You realize that these two statements are contradicting each other, right? The 9090 is the problem here, follow the above advice and check the optocoupler! Good luck!

Ja! Dann hast du alles fuer das Core-Modul, aber was du wirklich brauchst kommt auf die Anwendung an die du planst - also brauchst du vielleicht auch noch ein Display, DIN- und DOUT-boards fuer Taster/Encoder und Status-LEDs, etc. pp. www.ucapps.de gibt einen guten Ueberblick, die Seite hast du ja schon gefunden :-).

Very nice indeed - I am in a similar situation and would like to make use of my 525s, so I like your approach very much :-). I would probably chain the power connector, so that there is an in and an out connector on the PCB. A simple SIL header would probably do fine. And for the CV outs, it might be nice to have an additional DIL connector? Not sure if this would be feasible though...

That sounds way too long to be working reliably. Even 90cm is rather on the long side.

Hi, will you upgrade them to the most recent OS before shipping?

I have recently ordered some clear windows from Ponoko. The thing is that they don't do the groove that is required to glue it / hold it in place, so I have a lasered line where the groove is supposed to start. I'll then mill the groove along that line. I'll send pictures once I have this ready, and then I should have some spares as well if anyone is interested. The same goes for the MBSEQ display windows.

Have you looked at the MIDIbox64 page at www.ucapps.de at all? There, in the "Configuration" section, you should find the right tools to configure your box. Best, ilmenator

Which firmware are you using?

I guess this is a typo, and you are referring to the 4620? The 452 is supported... If I was you I'd write the seller an email and directly ask him. That way he can also show if he's a good, trustworthy, caring seller or not :whistle:.

Do you have the datasheets of the two devices to compare?
