Here is a Tascam TMD-4000 faderbank on *bay - looks like a set of motorized ALPS faders to me, but I am not sure as I have no service manual. For US people, in Atlanta, Georgia. Please don't bid on that one as I have "convinced" a buddy to bid on the article already. Thanks!

You should keep DINX and DOUTX modules, as you will probably also want to connect LEDs and buttons to the new platform?! :P Best regards, ilmenator

9 pcs left. Mouser price is EUR 6,50 each, only the jog/shuttle switch, without plastic wheels!

Up for sale are 15 pieces ALPS jog/shuttle SRGP type, including the two black plastic wheels (ring and center part) for jog and shuttle function, and three mounting screws. A data sheet is available here. They have been unsoldered from used equipment with broken electronics. I have not tested these units, but they should work. They are USED and most bear marks of usage, see the attached pictures - but none of them is in bad shape. The spring loaded mechanics feel very sturdy, no sluggishness whatsoever, and these devices are specified 50.000/100.000 cycles! Grab a bargain at 3,50 EUR each plus shipping plus Paypal fees (I prefer bank transfer, btw). I am located in Norway, but can send them considerably cheaper from Germany in the middle of March. ilmenator mb_P2224993.JPG mb_P2224923.JPG mb_P2224917.JPG mb_P2224882.JPG mb_P2224993.JPG mb_P2224923.JPG mb_P2224917.JPG mb_P2224882.JPG

Good boy!

General interest over here :)

What kind of help or discussion do you expect here? Everything has been said, over and over again, just look around the "Sale Request" section of this forum. I cannot find any new aspects in your post, and I find such discussions very tiring, to the point that I think "oh no, not again". The MIDIbox community's spirit is basically about helping each other to develop tools that are not available otherwise, and about learning how to DIY. One of the problems with your idea is that if you sell stuff, you will have to provide after sale service to "customers" who might not understand what they are doing. I would very much doubt that you are capable of providing this, infrastructure- and knowledge-wise. Customers would then turn to the community, but the community would refuse to provide help. This is where one of your problems would start, not talking of a number of legal issues you'd have to face. Did I mention that I'm really tired of this type of discussion? It's all in this post.

I see that I shouldn't have called you "young man", that indeed might sound offensive at your age - I am sorry. Rest assured, it was not meant to be offensive. It was related to the fact that to get an answer to your initial question ("how many AINx4 modules are involved in MIDIO128") you actually only need to read those two sentences I linked to above (and read the MIDIO128 project description to realize that MIDIO128 does not handle pots). Each AINx4 connects to 32 inputs, so if you need 64 pots that makes a total of 2 AINx4 boards. It is not a crime not to be familiar with the MIDIbox framework - and I guess you know that rhetorical questions like these do not really contribute to increasing your knowledge. Reading does.

Do your homework first, young man. If you would have read only the first two sentences of the web page describing the AIN module, you would by now know how many pots can be connected to one AINx4, and from that you would possibly be able to divide 128 by that number. The result is the amount of AINx4 modules you actually need for the MIDIO128 project. "Upping" your post, as you call it, is actually quite impolite in this case, as you apparently do not "do your homework" first, as we call it. This is the reason why noone has cared to answer your question. We are glad to help if you show that you really care - and that involves far lot more reading. And then, more reading. Regards, ilmenator

What do you mean by "already made modules"? Are you looking for readily built modules? You won't find that. After all, you have to do the soldering yourself, MIDIbox is totally DIY by definition!

Now this is really good news! (And I would like to see a picture of that nice display fully working in all its beauty ;)) I understand that you have the display running in portrait mode. There is another driver for the T6963C in landscape mode (and as Stryd mentioned earlier, it takes more processing power away from the PIC as everything has to be rotated internally by 90 degrees first). Still, would you like to try your code modifications on that driver, too, and report how that performs? Like you, I would not mind dedicating a PIC solely to the task of driving a display, but I'd rather know for sure that it can work before actually spending money. Best regards, ilmenator

Mit solchen "Fehlerbeschreibungen" wird dir leider niemand helfen können... Der Compiler wirft die Fehlermeldung doch aus, also kopier das zusammen mit dem Stück Code, an dem er meckert, und poste es hier. Wo konkret ist das Problem, bei dem du nicht weiterkommst?

Eine oeffentliche Diskussion waere schoen, damit auch andere "Mitleser" etwas davon haben, und die Loesung spaeter auch von anderen durch eine Forumsuche wiedergefunden werden kann! Danke, ilmenator

Phattline, I'd recommend to check the exchange rate, otherwise you might lose some money here.

I don't want to spoil your party, but what about taxes and customs duties?

Schau dir auf der LC Seite mal die verschiedenen Schaltpläne / PDFs an, dann wird das mit der Anzahl der Module auch klarer. Das GM5 bietet 5 Ports, also max. 5 Cores anschließbar. Du solltest dich daran orientieren, dass eine LC eine Mackie Control Einheit ersetzt - wenn du mehrere zusammenbaust, dann fühlt sich das am Schluss auch so an, als ob du mehrere Mackie Controls am Start hättest, die dann eben nebeneinander stehen. Genauso werden sie auch in deine DAW integriert. Jog, Transportfeld etc. brauchst du nur einmal in dem ganzen Setup, das kannst du an einen der Cores dranhängen (d.h. mehr DIN/DOUT Module), ein (G)LCD pro Core ist dagegen sehr sinnvoll. Siehe hier im WIKI bzw. im hier im WIKI. Mir scheint, du musst dich erst noch ein bisschen mehr umsehen, bevor du deine Pläne konkretisierst. Schau auch mal in der Midibox of the Week Abteilung des Forums, es gibt einige Leute hier, die bereits sehr große LCs gebaut haben. Auch das WIKI generell ist eine wahre Fundgrube für Infos. Viel Erfolg, ilmenator

Hallo und Willkommen hier! Zuerst: STM32 Core ist eine sehr neue Entwicklung, erst seit ein paar Tagen offiziell, und somit beziehen sich alle Infos zur LC auf den PIC Core. Grundsätzlich brauchst du für jede LC eine MIDI In und eine -Out Verbindung zu deinem Rechner. Das liegt aber nicht an MIDIbox, sondern an Mackie - die haben sich das damals so ausgedacht. Wie das MIDI Interface an deinen Rechner angekoppelt ist, bleibt dir überlassen - zB per USB... Und an dieser Stelle gleich: schau dir mal das GM5 Modul an - das tut was du brauchst. Und nur um weiteren Fragen vorzubeugen: Du kannst das Ganze natürlich auch in einem einzigen Gehäuse zusammenbauen, aber diese Modultrennung bleibt. Ein Core-Modul auf dem die LC Firmware läuft hat kein USB und wird das auch nie bekommen. Wenn du einen "vorgebrannten" PIC kaufst, musst du lediglich noch das aktuelle MIOS per MIDI übertragen, am besten mit MIOS Studio. Danach folgt das Übertragen der eigentlichen Applikation, also in deinem Fall der LC Software, ebenfalls per MIDI / MIOS Studio. Die GM5 Chips sind bereits komplett "gebrannt" und brauchen nur noch aufgelötet zu werden. Grüße, ilmenator

That's nice - how about adding a screenshot per object to the WIKI so that one can see the beauty immediately?

Hehe, now I get your point: you / him would want to use the MBLC app without modification - of course, then you need to do something like that. Still, you could "simply" modify the MIDI OUT routines... (Probably too big a job for an assembler noob, though - I would not try to do that myself :).) In hardware, a 74HC04 will do the job nicely. For inspiration, see this PDF, replace the resistor and LED (e.g. R16 / D6) with another inverter. Or look at the Bareille design.

Actually, I was saying that the Core module with just the LCD(s) attached is sufficient for that, as it has a MIDI in and out. No need for an additional Thru box here. :)

Or you just forward the incoming MIDI stream as is to the Behringer. MIDIbox just picks out the data that needs to be displayed on the LCD, but leaves it untouched. (I assume that everything that the Mackie Control displays is coming in via MIDI, and is not data that is created in the unit itself?)

From their website: [tt]# Minimum order is USD 2,000. # For orders below USD 5,000 a handling fee of USD 100 will be charged. # Payment is required by wire transfer.[/tt]

Yes, you can - you can configure each port pin separately to be input or output.

This topic has been moved to Design Concepts. [iurl]http://www.midibox.org/forum/index.php?topic=12839.0[/iurl]

The short answer is: MIDI is a digital signal transmitted on a current loop, so you do not really have to worry about impedance. The physical layer of that interface is standardized - follow that standard and you are fine (all MIDIbox devices you can find around here are adhering to that standard!). The long answer is far more complex, you best start looking for Electrical Impedance in Wikipedia. Best regards, ilmenator
