Buttons and Pots are "Inputs" - you send a status over a DIN/AIN to the core, to tell it, that the button is pressed or the position of the pot. Your LEDs are "Outputs" - The core sends the status to the DOUT-Board, which controls the LEDs. http://ucapps.de/mbhp_dout.html http://ucapps.de/mbhp/mbhp_doutx4_32leds.pdf Greets, Roger

Open a datasheet. In the middle of the 1st page you can find the "Explanation of Part Numbers" Digits 1-3: ProductCode = fix (it's this type of fader / housing /physical built) Digits 4-6: Specification - Q = 60mm type, 1 = single taper (see 2nd page - drawings) Digits 7-9: LeverTrims & Dimensions - I think there is only one type available (see drawing) Digits 10-12: Taper & Resistance - I think "B" is linear So you probably want: EWAQ12C15B14 Greets, Roger

... the more you look at it or the more you read about it from others? ;) Don't depend too much on the opignons of others. There is propably no other business than audio business where more bullsh... is talked and called out to the world, without having the necessary knowhow to even open the mouth :P Greets, Roger

... no, new faders won't make the resolution better. The resolution is given from the AD conversion or in the processing of the controller.

Absolutely! Not doing so is not cleaning but just smearing the dirt around. Alps recommends to clean the taper with alcohol. This recommandation is for plastic taper. AFAIK, Alpha doesn't produce any plastic taper faders. I think alcohol (aethanol) or isopropylalcohol works for carbon taper just fine. How about just replacing those cheap faders? Greets, Roger

Kannst Du nicht mal ein paar scharfe Fotos Deines MF-Boards posten (beidseitig)? Ich würde mal auch die Pins der Board-Verbindungen prüfen. Z.B. Das MF-Board vom Core trennen und nach Schema mal die Pins von J2 checken, wo Du welchen Strom drauf hast. Lötstellen von C5 gut prüfen usw. Grüsse, Roger

... was ist Dein source? AC oder DC? Grundsätzlich bräuchtest Du den Gleichrichter bei DC nicht, sollte aber kein Proble sein. Grüsse, Roger

... this was not a joke. I think I first saw that on Doc's LC. Actually not multible powersupplies, but multible regulators. Just redesign the MF board, so you have a regulator (incl. Trimmers, resistors...) for every single fader. Greets, Roger PS: But I still think that this is not really the problem of your Box' behaviour.

Wieviel Strom bringt Deine 12V Quelle? Welche Fader - Marke, Typ? Alps spezifiziert sämtliche MFs mit Max. .75A - Habe aber noch nie erlebt, dass soviel gezogen wird. 8-Fader ziehen aber locker 1A zusammen Wieviel Volt hast Du am Regler (MF-Modul) eingestellt? Grüsse, Roger

... well done - Nice box! I hope you don't mind that I moved it to MBotW. Greets, Roger

... I was on the Adobe webpage but couldn't find anything like this. A good practice when asking questions about specific products, is to include a direct link. Greets, Roger

... they still are used today. When I was in the Army, I was a tank driver and we had them for internal communication. Since my head stuck out of the driver's "hole" and the engine exhaust was right next to my head, you wouldn't had understand a word from me, since the noise of the V10 engine was so loud. - As I recently saw, they still use them. I can't make a statement about the sound quality of them, since I only was listening to them over the communication system, which had low-cut at about 300Hz and a big boost at 3k... for better speach understanding. Greets, Roger

... just that the USA didn't "enter" the war in 1939 already ;)

... how much? I think you can tell, since we're not talking about your work payment. Greets, Roger

... denke schon, wenn Du den Titel nicht endlich korrigierst :P

... it's in the nature of the MIDI protocol Greets, Roger

... welcome to the club :D

... read /tilted/'s reply just above. Greets, Roger

... oder einfach verstehen, wie ein Encoder mit GreyCode funktioniert und halt gleich eine entsprechende Schranke von "Honeywell" verwenden und das 3 Dioden Gebastel lassen. Quatsch: Mit einer Diode würde es gar nicht funktionieren und mit 2 bekommst Du einen full-cycle, welcher Dir 4 steps "liefert" ... weshalb nicht gleich Kugellager als "laufräder" nehmen? Die gibt es nicht nur mit flacher äusseren Schale sondern auch mit V- und halbrund-groove (somit zentriert sich der Riemen selbst). ... 3-6cm Durchmesser? - Überleg Dir mal, welche Auflösung Dein Encoder haben müsste, um auf 10cm Slide-Weg noch eine vernünftige Anzahl Schritte zu bekommen (6cm Durchmesser gibt Dir einen Umfang von ca. 18.8cm, was heisst, dass Dein Lafrad gerade mal ein halbe Umdrehung machen würde). Es müssen ja nicht gleich 1024 sein, wie bei einem konventionellen Fader aber ich denke, 256 sollten schon drin liegen. Grüsse, Roger
