Bonjour L'ampi-op va vite fumer si c'est pour piloter un moteur... Cordialement Zam

Bonjour Cela dépend quelle stratégie est utilisée pour activer/passer d'un set de bouton à l'autre, bank ? radio group? Dans .NGC avec value= il est possible de définir l'état de départ d'un EVENT Dans .NGR avec set/change event (section 0) il est aussi possible de définir un état au démarrage Cordialement Zam ps: le forum en anglais est plus actif...

Happy new year to all. Wishing everybody a lot of good things Best Zam

Hello Jerome I just let you know if you miss it, MIOS have debounce handled at soft side. Best Zam

Hello That's a nice first post ! Bravo Zam

Yes should be possible, certainly different options, with conditional at NGC, or set_active at NGR. However you have to think it a little further as you may have domino effect with the mute function if you just do a basic logic You have to define situation you don't want the flash without locking the mute LED for simultaneous state you need a mute... Best Zam

For button, Sysex trick only one way, MIOS can send it but not receive it. For led, all them triggered by value (on/off with formatting) and activated only if zone value match Best Zam

Ok, here it is.

Hello 2hb I guess you try to set all this in HUI mode (which is not sysex !! ) I have an beta/optional NGC/NGR version for a control surface in HUI mode. I'll check it and share the code strategy for this purpose asap, it's tricky... Best Zam

Hello Good ! that will for sure simplify a lot the conversion to Midibox IO side note, I'm interested to see the PCB assembly to front panel ! Best Zam

hello This is not LED this is filament lamp, they are in the button, depending of manufacturer you should be able to remove the top transparent caps and have access to the lamp, is that EAO switches ? If they are T5.5 filament you can replace them with LED (available in T5.5 package) I guess they are 24V rated, +LAMPS in the schemo should be a separate 0V/GND for all lamps, as the -25 dedicated rail for "power" light It should work. and if led/button are in a daughter PCB at frontpanel It should not be that difficult. Best Zam

To me 140mA make more sense for BAx bulb or 14mA which is low but in the range for T5.5 bulb... Also 14A is not in the common range for most DMM... @2hb can you confirm your A meter setting? mA or A ? Best Zam

Hello 14A ??? are you sure of that ? it's about 170W Please give use the ref of your light bulb to ensure no measurement mistake at your side. As Latigid say, no IC will help you here, you better use a power relay Best Zam

Yes... IIRC you already have issue with your LEDs before with AD chips Seems that those RGB led strip introduce LOT of noise all around. So careful design seem requested ? maybe a topic alone about this can be open, to share and set good practice for designer that introduce RGB leds, which seem to become more and more used by various members now. Best Zam

Hello Tedy I don't have the answer to your specific question, BUT there is no need at this forum to post 4 time the same question in different sub section... Best Zam

hello The Juno is now closed (with an audio IN mod) but here I find pict (faster to me to google search than opening the enclosure, take pictures, and upload it ...) http://studiorepair.com/gallery/Roland/Juno-60/slides/Roland_Juno-60_Opened_Right__STUDIOREPAIR_09101301_1009108175.html you'll see the voice/cpu board with silver foil behind, the PSU have L plate that also serve as disipator for regulator there is also a foil at left hand bender board. Best Zam

Hello You may have an issue or faulty channel because it's seem out of the DA spec ?!? Best Zam

Hello I don't say that, I say wood is used as aesthetic over metal case or with extended metal foil screen. For example I service and mod a Juno 60 yesterday, the bottom/structural panel is plywood, with pcb attached on him, there is adhesive Al foil all around It will also protect for EMI/RFI !! Both way, our lovely midi box can be noisy at digital lines (I learn it the hard way with my build close to discrete audio circuit) as catching perturbation from over populated electronic environment these days (computer, SMPS, all box in our room with digital electronic) Also you say you have 3 DC-DC converter in your build, still 150khz switcher. The one you show is open frame, maybe a screen around them can help too... Best Zam

again.. I don't get your point here, MB_NG is so easy, there is no C involved for setup... You can't ask for deep access in a system and in the mean time asking no work at your side to handle it. MB_NG have mostly every things you can think about without any effort... by the time you'll use it and find limitation, you'll be able to code in C Best Zam

Hello Fantom Make more sense now If it's a ESD issue (Antichambre also suspect it), it may be completely unpredictable... room temp, humidity, what clothes you have today... Put Cu or Al foil everywhere at inner wood panels, you may also reduce EMI/RFI. Wooden case is nice, but if you look you'll never find any manufacturer using wood other way than cover only (over metal) or completely foil protected. By the way, your controller look cool !!! what are you using across fader, RGB led bar ? Best Zam

Hi Fantom Ok so you have an external supply, does it output 19V AC or DC ??? In case it's DC why are you using a SMPS after and not a DC-DC convertor or regulator ? In case it's AC are you sure your SMPS is able to handle 19v as input ? If everything is safe/no metal part available for user you don't need to connect your electronic 0V to safety earth BUT as your supply chain still unclear to me I'm curious to know what voltage you have between pcb 0V and safety earth (wall plug). Best Zam

Hello Zener MB_NG setup don't need any C knowledge if you stay with the implemented functions, which are already huge and powerful.. Best Zam

mmm... maybe a screening will help what do you call GND here ? which side of the power supply ? I'll definitely suggest to hook psu primary "GND" to safety earth, especially if you have any metal part accessible by user. For your 0V ref "GND" at secondary, having it hooked at one point is recommanded too... If you have a SMPS fully floating, what you call "GND" is just a reference that may float way far from AC wall plug earth... No offense but please inform yourself, and get used to 0V(ref), Ground, and (safety)Earth concept Especially to avoid any electric shock if fault occur. But also to properly handle current flow and solve "noise" issue , which seem your case here, where your ESD to the system change in an erratic and unstable way your floating "GND". Not to mention some component can be destroyed by ESD... Best Zam

Did that mean your electronic is floating in a metal case not linked to "earth" ? Best Zam

Hello Maybe the sysex header depending of how deep you want HUI function with your controler The link I give you have about everything possible regarding HUI data type, which is midi stream but not midi standard form... Most can be handled by MB_NG with event definition at NGC or script at NGR with more or less trick. Best Zam
