... well I thought it will work ;) ... but I would like to know why. - Why does the datasheet say: 800mA? http://www3.alps.co.jp/pdf/2004pdf/pdf_e/Potentiometer/Mixers/mortor.pdf Greets, Roger @Raphael: Sorry, I never answered you the question about Switzerland: Yes I'm from the German speaking part.

Thanks guys! I read in the datasheet for the ALPS faders, that max. used Motor current is 800mA. I'm planning a 24 Fader Box and it's possible, that as a snapshot all faders have to move together... where do I get a 19,2A 12V Powersupply (no switching type) from? I see on Thorsten's LC-PSU-pdf, that he uses a 1,5A fuse for one MF-Board (8 faders = 6.4A)... can somebody explain me that? Is that because there are only pulses driving the motor? ... and another question: Is it possible to connect PSUs in parallel like batteries to raise the possible current? If yes, any type? Greets, Roger

... is it possible, that they are chosen that low to protect the powered equipment they have to supply? Greets, Roger

Hey t ... usually a pot has about 300° (far left to far right). There shure are some pots which have like 10 turns (precision pots). Sometimes used for motorized pots mounted at the primary gear side (attached to the motor). - I think p&g motorized joysticks work like this. So when you turn the shaft 300°, the pot actually makes 10 turns. No. They always have an end (lowest to highest resistance). Rotary just means, that you turn it around it's own shaft. What you mean, is an endless rotary encoder. Every detend is one pulse sending to the digital input. A pulse, telling the host software to adjust the pan (for example) one step to the right or the other way. When the position in the host software is at it's end (example: left) , you can go on turning the encoder counter clockwise (sending pulses) but the position (in the host sw) stays far left till you turn the knob to the other side. ...when you slam a 300° clockwise it's hard right as well... ;) Yes... but no detend in the middle position. A touch function you only need for motorized pot's... to tell the motor to stop driving when you want to take over the adjustments (touch write function in your host sw) http://www3.alps.co.jp/pdf/2004pdf/pdf_e/Potentiometer/Metal/rotary_motor.pdf I would suggest, that you take an encoder. You even can take one with a switch (push the turning knob to close the switch). You can program the switch to send a midi event to tell the host sw to jump to the middle position (instead of a pot with a detend in the middle position) Greets, Roger

Checked www.albs.de? I don't understand why 180° ??? This will make it to sensitive (shorter way per total resolution). I don't know an analog mixer pan with 90/90° Greets, Roger

No I didn't... too late  :( I'm done. -  Now I propably own the most expensive rack rails in  the world  :-* (calculated approx. 6 hours) Here the printing on the power regulators: - the 5V units use Sanken SI-3554M - the 12V units Sanken SI-3120M http://www.sanken-ele.co.jp/en/index.html I can't find any datasheets. Not on the Sanken site (they just write: discontinued) nor by google. Can anybody help? Does anybody have one of those electronic bibles in which you can find all the data of transistors? Greets, Roger BTW: The fuses you can see on the frontpanel are on the secondary side. The main also has fuses built into the socket: T315mA/250V

... for the drawbar: Why not building your own belt controller? Should be pretty easy driving an encoder by a transparent silicone belt. http://www.pennyandgiles.com/docGallery/85.PDF Greets, Roger

Hey jjucius ... see this forum topic from the portal.midibox.org for more information: http://www.avishowtech.com/midibox/modules.php?name=Forums&file=viewtopic&t=2&sid=79f68af3d95cac19b5cdbe6e217435d9

1x Core http://www.ucapps.de/mbhp_core.html 1x DINX4 (falls Encoder an Stelle von Potis verwendet) http://www.ucapps.de/mbhp_din.html ... für normale Fader: 1x AINX4 http://www.ucapps.de/mbhp_ain.html ... für 16 Motorfader: 1x zusätzliches Core 2x  MF Module http://www.ucapps.de/mbhp_mf.html anstelle der Encoder (an DINX4 board) können auch Drehpotis verwendet werden (am selben AINX4 wie die Fader - nicht Motorfader) Die Fader und Potis müssen 10kOhm linear sein. www.albs.de Grüsse, Roger

... molding. - Take the original wrist rest as the "master" Greets, Roger

;D hehehe... good old moebius ;D ... I'm just waiting till he's pulling on my leg ;D

for example... http://www.ucapps.de/midibox_lc/midibox_ng_switching_psu.pdf Greets, Roger

... bake it in the oven (what temerature?) or with a heatgun? Greets, Roger

... seems like it is easier ;) You have to remember, that there is also an encoder sitting in the middle of the ring :-/ http://www.midibox.org/cgi-bin/yabb/YaBB.cgi?board=concepts;action=display;num=1104455259 ... yes they can be bent. I bought some of these from "voti" http://www.voti.nl/shop/p/LED-4.html Greets, Roger

Thanks a lot guys! I will deliver the information, as soon as I find time. I'm quite busy right now. I'm building my studio furniture and made a mistake in design. - Now I don't get the appropriate rack rails and have to build those as well. This means drilling about 400 holes and cut the windings for the screws into those "blank" rails by hand  ::) ;D :D :-/ :( >:( :P Greets, Roger

... kenn mich nicht aus mit Cubase. Ein Link zu diesem UC16 Controller wäre aber nicht schlecht, damit man sich was vorstellen kann ;)

... the strip on the bottom of the faders to name the channels (Example: VOX,HH,Guit,Keys...)

http://www.pennyandgiles.com/docGallery/78.PDF P&G / M3222 has your spezifications... Greets, Roger

... with the keyboard is not MIDI In/Out those are keyboard commands based on the windows rules. The advantage of controlling some functions by MIDI, is that no matter which window is active on your computer monitor, your host software will execute the command. ... why not ;D ::) :-X What you could do: Design a new hand-rest and extend the functional mixer surface towards you by about 1.5 Inches. This way you could put the original hand-rest pieces in the cellar and mount them again for reselling the mixer at a later time. Advantage with some buttons: Automated "Mute" and channel selection. ... I think I saw something like this from P&G. They call the linear track "servo track"... not shure about that... just surf their specs files. http://www.pennyandgiles.com/index/map.asp Greets, Roger

... it's just another resistive plastic slide track on the fader. for every track you can chose it's resistive behavior (linear & log). You can say: I want 2 tracks with log behavior or one linear and one log or two log... ... yes. But I think this is not available. You have to build a left and right channel fader. ... with P&G and TKD ... if you want to implement it under the LC protocol (locic Control / Mackie Control): 8 Faders per MIDI In/Out... I think daisychaining all of them would give you a to high latency anyway. If you work with the MididBox LC, you don't have to program much .. don't you wanna extend it with some buttons... at least a play, stop etc. button? Greets, Roger

... as far as I know, they even don't come without touch... and I'm so used, working with touch, that I think I couldn't live without anymore. ... Yepp! - About 45 Euros ... you don't need a switch. You would take a RSA0K12xxx (C stands for: coreless motor). This type has the standard Touch track, and the choice of, for example, one linear track and one log track. So you wire the linear track just like in a regular Midibox LC and the log track in the line of the analog mixer channel strip (nicest would be to replace your mixer faders physically). With that you have the choice to work natively within your host DAW software and use the faders to control the DAW mixer or you use the analog mixer and use your host just as a mixer and multitrack player for mixdown. When you use the analog mixer you will have the problem that your software mixer faders will move as well, so you would have twice the attenuation. So just use the bus outs (prefade / direct out) and patch them internally to your DA converters. Greets, Roger

... yes they did, but no moving faders :-/ I'll go with the Alps K-Type fader (almost same quality & price as P&G). But electronically they have exactly the same data as the "cheap" N-Type fader. I hope they work from the beginning :P Greets, Roger

Since the touch function works by grounding when you touch it which gives a difference in potential, I would say, you have to connect them to ground. I don't know about you should connect it over a resistor. Please search the archives... I think I once have seen a post, concerning this. Greets, Roger

Thanks a lot Raphael As soon as I have the info from these MOS FETs, I'll publish it. BTW: My english isn't better ::) ... so we had this so called language barriere ;D Thanks so far Greets, Roger
