Nice work Edis! I specially like the buttons... Foil over the switches? Greets, Roger PS: Moved the post "MidiBox of the week" - Hope you don't mind...? :)

... no programming needed at all. Just use the MIDIBox LC and assign "virtual" mixer tracks in your DAW (... as you stated above) ... no LCD needed. If you run into trouble during building the modules, you still can buy one cheap from Ebay for debugging purposes. ... yes, keep the MFs supply away from the analog mixer's one ... regular carbon will do (I don't even know the "size", but don't worry bout the power...) ... AFAIK all DAWs can handle at least 4. But there is a limit on some - Sequoia and Samplitude only can handle 4 at the time. ... no, no prob. There are even caps to mount horizontally. You have to check by yourself what fits best (it's only a matter of where the contacts are placed) ... I think I wouldn't connect it, since the cover is grounded by the chassis (frontplate) ... hmmm... don't know - I'm no analog audio circuit freak :-) No, no talking out of it. About the noise...? Just try it with one fader, as you stated and don't worry about gearslutz and prodigy - So much bullsh... spread there (...though not all). Greets, Roger

Well... you're having the shematics now and you can take it out of it, what voltages you need. I think I would hook it to a LaborPSU and measure what the circuit draws while in heavy use (when the MFs are moved). Greets, Roger

... you did not answer this question: Can you measure the primary side of the transformer at the solder joints? Greets, Roger PS: Since this post goes into the direction of servicing a non-MidiBox, I'll move it to "Misc"

If you're using this Alu-Dibond material (I also thought about using it once), you need a solution to make sure, that both metal sheets get properly grounded. If you're using M4 counter sunk screws with a 2mm dibond sheet, this should actually be granted, since the counter sinking will go all the way down to the lower aluminum sheet. But if you use e.g. M3 counter sunk screws with a 3mm sheet (usually the straight whole would be 3.2 mm then), the screw gets centred from the counter sinking and it is possible that the lower aluminum sheet does not touch the screws and therefore the lower sheet would be ungrounded. In this case you'd have to scratch away parts of the protection foil from the lower aluminum sheet to make some additional contact to e.g. the metal case or jam in a grounding cable if you use a plastic case. Greets, Roger

You probably would best go with dual linear taper motor faders. One Taper with 10k lin for the midibox and the second taper depending to what the faders currently (VCA-Controller Fader) have - Probably also 10k lin. I think these faders won't be available as standard. Another solution (if the console also uses 10k lin) would be a mode-switch for each fader... maybe with reed-relais. Then you would implement a master mode switch in your Midibox (DIN) and control the reed relais over a DOUT. This way you could switch your console back to VCA functionality and back with one button press. Another possibility again would be to control the faders with MidiBox and send the fader position over AOUT back to the VCAs (might be a bit expensive fro 64 Ch). Your console probably also has touch functionality. If yes, then it gets a bit trickier. What you could do, is checking if you can pick up a "touch activated" signal from somewhere in the existing circuitry to send to e.g. a DIN board. ... and yes, LC is probaly the best basis to work from. Greets, Roger

I think Seppoman made use of them about 2 years ago. He had to do some fixes in the PIC-Core display driver. Greets, Roger

MF Touch Fader Connection Greets, Roger

:whistle: ... genau meine Herangehensweise. Bei gewissen Fragen, welche ich eben gelesen habe, musste ich mich fragen: "Hmmm... bin ich mit meiner <Geht Sie einen Dreck an...> Einstellung ein Schwerverbrecher oder wirklich nur ein hobby mässiger Steuerhinterzieher, welcher vielleicht mal auf die Frässe fallen könnte und den's aber nicht wirklich beängstigt?" Falls es Dich mal erwischt und Du einen Strafzoll obendrauf kriegst, klaust Du dem Beamten den schönen vergoldeten Kugelschreiber, welchen er Dir zum Unterschreiben des Nötigungspapiers hinstreckt, dann geht es Dir beim Rausgehen fast so gut, als hättest Du keine Strafe gekriegt :tongue: - Würde mir wirklich nicht zu viele Gedanken machen :smile: Grüsse, Roger

I think all the LED-Rings I have seen in finished MidiBoxes have been wired down to the PCB. Greets, Roger

Ich würde mal mit MidiOX schauen, ob die Commands, welche Du vom PC sendest auch ok sind. Grüsse, Roger

... from the spec side, yes. To find out for sure, you have to try - I never hheard in the forum that somebody is using them. I even didn't know that they are making MFs too. Greets, Roger

Ich weiss nicht genau, von welcher Anleitung Du sprichst aber ich nimm an, dass es sich dabei um die Block-Kondensatoren vor den ICs handelt. Diese sollten so nahe am Pin sein wie möglich, so dass möglichst wenig "Leitungs-Weg" übrig bleibt bis zum IC, auf welchem die Speisespannung durch äusser Einflüsse noch beinträchtigt werden könnte. Grüsse, Roger

Ooops... die halbe Menge Zinn hätte es aber auch getan :twitch:

Yes, use MidiBox_Link. Though I can't remember anybody posting who used it on MidiBox LC - Give it a try. Greets, Roger

... what now? :rolleyes: The answer you see in my previous post above: "Regarding the connection of the units, it depends on your host soft. In Sequoia I would connect the master-unit as an independent unit on its own midi port. If you want to connect it together with an 8-fader unit onto one port and handle it as the "master"-controller, you probably have to make use of MidiBox-Link." Greets, Roger

Hi Lu Taska Yes, for your Master Fader, you need an additional core - Do you really need a Master? - Think about it. Regarding the MF-Boards I would suggest, that you take 2 and the single Master Fader you build just partially on a stripboard. Regarding the DIN/DOUT boards you see it correct but I don't feel for counting it through. Regarding the connection of the units, it depends on your host soft. In Sequoia I would connect the master-unit as an independent unit on its own midi port. If you want to connect it together with an 8-fader unit onto one port and handle it as the "master"-controller, you probably have to make use of MidiBox-Link. About how many LTCs - Go for one GM5 Greets, Roger

No issue... I think you're German, so you have the same problem as me... I also don not always hit the correct term :-) ... and yes, I's worth the time... but be aware of the potential of addiction :shocked: Greets, Roger

Basically I would say, yes you can use the encoders. Though I don't know what "2fach Rechteck" is exactly. About the LED ring, you need to know the matrix constellation. Best for Encoder and Ring: Get the datasheet from the vendor. Switches (these are not knobs): Yes, they should work for you. Greets, Roger

Please use the forum search - You'll find plenty of topics regarding this. Greets, Roger

Yes Greets, Roger
