The 5V at the output of the SR / the input of the ULN are always there. It doesn't matter, if I press a key or not. I need to replace "type=NoteOn key=36" with "type=cc cc=1" to get something out of the ULN. I get 1,2V out of the ULN to D7 by pulling up the CC1 fader in MIOS Studio. I never got 5V out of the ULN. If I leave "type=NoteOn key=36" I measure 0V with pressed AND depressed #36 at D7.

Hey! I disconnected the rows from the DOUT but leave the coloums connected. Here is what I did: I used this code: I measured the input of the ULN, which is 4.9V. I measured the outputs = 0V. I pressed key #36 and measured the outputs again = 0V. I changed the code to: I measured the outputs = 0V. I pulled up the CC1 fader in MIOS Studio and measured again. D7 is at 1,2V. All the other outputs have a small voltage too. See picture attached. I'm really not sure, where to look for the mistake. I also tested it with another DOUT module. Same here. Also it seems, that button_mode=Toggle isn't working at my side. I also tried to again upload MF_NG without any results.

Thanks for your help. I tried, what you were suggesting. At first I copy&past your code into my NGC. By pressing #36 nothing happened. Also pressing #40 all LEDs stay dark. I replaced "type=NoteOn key=40" with "type=cc cc=1". When I use the slider, I can switch on and off a array of 4 LEDs. This is not working on the rows. If I replace "type=NoteOn key=36" with "type=cc cc=1", nothing is changing. It's still not working... I measured the rows and it's at 2,8V.

Maybe you got me wrong?! Of course I want to do it, but I'm not sure, how to code that...

I'm not so much experienced with coding. So please excuse my "bad coding". I tried just this EVENT_LED id=1 type=CC cc=16 rgb=0:0:15 Nothing happens, when I use the slider. Same with keys... everything is dark. //edit: I did draw a diagram, that shows, how I connected the LEDs. The color of the boxes are the rows, the number is the led.

As you can see in the picture attached, I'm able to set the color for every single LED. Because my wiring was very (!) time consuming, I don't want to rip it all up. And I don't get exactly, what you mean. Maybe you can explain more into detail? I really appreciate your help!

And another question: I now connected all red and green LEDs. I have a problem: I can't swich the LEDs off. I tried rgb=x:x:x to 0:0:0 and also tried to set the value to 0. The LED are still on... they are low, but they are on....

Still looking for DOUTs...

Works perfect!! Thank you! ;) Is it possible to set up an encoder to scroll / fade through all the different possible colors?

Hey! Is there someone, who has a 49-76key keybed left? Looking for a qualitykeybed from fatar, roland, yamaha, etc. I'm located in Germany. Thanks! Chris

Thank you so much! I will keep you updated!

Thanks for this hint! I will check this out tomorrow and give you a status update. Should I take 82Ohm or standard 220Ohm resistors? But the code should work you say?

Okay, here we go! I now connected 4 rows with 16 LEDs per row to D0:D3 of SR1. For now I just connected eight (8x4) of the green LEDs to D7:D0 of SR2 to see, if it's working. I connected the DOUT with the core. The first SR has no resistors, just bridges. SR 2-4 are equiped with ULN2803. I put a 82Ohm resistor to each output (so, 8 resistors). I tried this code: But... no lights... nothing happens...... any suggestions?

Hey TK, yes, I already realized that by myself. I now wanna use single square-LEDs which I connect in a matrix. I will get the CCs from bidule. That works on my iPad perfect.

I'm really not much into SysEx, but just a short question: Is it possible to send SysEx from a computersoftware (like MAX or plogue bidule) to the core, which changes the LCD message? If yes: Is there a kind of "sysex-creator" for text? I'm asking because Mainstage is not able to send tracknames (in difference to logic). I want to use Plogue Bidule instead to do this after every patch change. Will be a lot easier, than programming patches on the MB_NG.

Hey thorsten, That makes sense. But is there a way to calibrate the exp pedal without a crashing software? :) I want the pedal to go from 0 to 127. Thanks!

As mentioned in a thread (MB_NG) I've tried to connect my expression pedal to the analog ins of the LPC. It seems to work, but I've got jittering values (about cc-value 122 in one direction, 6/7 in the other) . I tried to connect a resistor between 3.3V and the pin on the exp-pedal. Same here. I saw, that there is a "calibration" function in the menu. When I try to calibrate, the monitor gives me a LOT of informations. But I can see no change if I pull down the exp-pedal. At this point the application (or MIOS Studio) hangs and the only thing I can do, is plug off the USB from the computer and restart the application. Is there a way to manually calibrate the pedal? Because now the monitor says, the min_value of the analog_in is 0 and the max_value is 255.

Thanks! I will try that... hopefully tomorrow morning ;) //edit: Moved it to MB_KB Thread. I forgot that my keyboard is running on MB_KB and not MB_NG.

Thanks for your help! Another one: How to connect an expression pedal to the LPC? It has a stereo jack, so I assume, I need to connect GND to GND, tip and ring to a separate analog-in on the LPC. But how to assign them in the NGC so it behaves like one controller?

Hey, I just ordered a bunch of those bargraphs: http://www.reichelt.de/index.html?;ACTION=7;LA=3;OPEN=0;INDEX=0;FILENAME=A500%252FGBG1200%2523KIN.pdf but now I'm wondering, how to connect them to the DOUT, because some LEDs are using the same pin for supply and ground, if I get it right... Thanks, Chris

Hey, nothing more to say. Looking for someone in Germany, who has a DOUT-Modul (best from SmashTV) and / or a PIC, which is bootloader-programmed, for sale. Mike has no PICs at the moment and will be on holiday till 1st of July. Thanks, Chris

Great! I drawed a schematic. But I think I need to sit right in front of the LEDs to know, where which wire to solder ;) But all orders were done today. I should get a few nice packages the next days. I forgot to mention: I have some PCBs with a led ring on it. Its 0603 warmwhite SMD LEDs. How to connect them to the two DOUTs? Is that possible or do I need a dedicated DOUT for those LEDs? If I connect them all to one color-SR there shouldn't be a problem, right?

Cooles Projekt! Du hast mich da noch auf eine andere und viel einfachere Idee gebracht. Als Keyboarder kann man ja bekanntlicherweise nie genug Sounds gleichzeitig abfeuern. Hände sind auf den Tasten... da kam mir die Idee, eine Art "Fuß-Pad" zu bauen. Der Fuß macht sowieso die ganze Zeit den Takt mit. Für Claps, Snares oder Bassdrums natürlich wie geschaffen. Könnte ich dafür einen solchen FSR benutzen? Und sollte man dann tatsächlich einen Schmitt-Trigger davor setzen oder erledigt das die Firmware des MBNG von selbst? Auch mach ich mir Gedanken wegen des Gewichts. Zwar stemme ich nicht mein komplettes Gewicht auf den Sensor (ich sitze beim Spielen meistens), aber der Fuß an sich und die Kraft, mit der der Fuß im Takt mit macht, ist sicherlich höher als 10kg. Käme wohl auf einen Versuch drauf an. Wenn man den Sensor zwischen zwei Schaumstoffplatten steckt, könnte das funktionieren.

Yes! I draw a diagram in Eagle to make it clear. Because I need to use a second DOUT anyway, the first matrix will be 6x8 (six RGB LEDs in eight rows). Did I get it right, that the first SR sets the rows. On the second SR I need to connect all red LEDs (which would be six lines, each with 8 LEDs), third SR all green, 4th SR all blue. Cause your schematic in this topic says something else.

Thanks! I read thru the thread. Interesting stuff out there! ;) I want to use ULN2803 drivers anyway to drive the LEDs. I hope, I don't need to setup a 16x4 instead of 8x8 to get good brightness levels. I think I need to hook up some kind of schematic to not get confused by all the connections ;) Anyway: If I want to use more than 64 RGB LEDs it's necessary to use a second DOUTx4 or it's possible to enhance it to a 10x8 matrix?
