Thanks for making it clear!

You need to set inverted=1 in the NGC when using an ULN: Another idea is to cut off the 5V of pin10. As far as I know pin10 should not be connected to anything (if I remember correctly in conjunction with a DOUT module).

Come on... fast, cheap and 4-layer? Not possible in my opinion! Even 2-layer is very expensive if you need it that fast. Anyway: I already ordered at elecrow and seeed studio. Both are very good. I think the communication with the people at elecrow is a bit easier and they ship faster.

Nobody is able to doulbecheck the layout?

Long long time ago :-) I still have those sensors next to me. Any chance, that we can work on it ? :) Thanks! Chris

Thanks for the reply! You are totally right! Sorry for the confusion!

Hey TK! Yes! I did update the file browser.

Just another hint: Don't you think that it would be useful to delete NGC files from the SCS? As far as I checked it you can only save and load files. And another one: Is it possible to access the DISK-menu without switching to the SCS menu first, scroll through the list and call it? A direct access would be also great :smile: Also a "save-button" would be a nice enhancement. :) So a config-file could easily be saved without going into scs. Bug-Report: When I save a file to the SD-Card through the SCS I'm not able to open this file in the MIOS-File Browser. It says "Failed to access /XXX.NGC".

Wow! I just checked that! What a great feature! ;-) Just one thing: To meta-learn a controller it's now necessary to send a value from the computer to the midibox (via mios-studio or a host). Is there a chance to have it independent working from a computer? Let's say we want to control a hardware-synth. It's not common (as far as I know), that synths send controller data out but they receive them. So it would be great, if there would be an option to let the midibox listens to itself (without creating a midi-loop of course). This could be useful, if I have one potentiometer for resonance and another one for cutoff and I want to control both values at a time with another encoder f.e. What do you think about it?

Hey people, with the help of TK a while ago and a few modifications this code allows you to send program changes in conjunction with buttons... in my case I used buttons from Marquardt type 6425 with numeric keycaps (you can get them at conrad). When TK wrote this code it had the limitation that I was just able to send prg.chg. to a maximum of 127 which is the midi standard. In my case I needed more! My software listens on all channels for prg.chg. So I added a little math to it and now it sends automatically 0-127 prg.chg. on chn.1, 0-127 on chn. 2 and 0-127 on chn.3 depending on the value you type in. If you give him f.e. 128, it sends prg.chg. 0 on chn. 2. If you enter 383, it sends prg.chg. 127 on chn.3 and so on. So, here we go. This could you want to paste into an NGR.-file: Of course you need to add also a little code into a NGC.-File: Please adjust the ids to your needs. If you are working with a display, here are the correct lables: I hope you like it! :-) Thanks! Chris

But they aren't necessary, are they? I used a lot of Bourns PEC16 Enc and never had trouble with those without the filter.

Bei Doepfer bin ich auch raus. Allerdings haben diese Potis meist einen gemeinsamen Anschluss. Mit MIDIbox würdest du die Masse des DIN mit der Masse des Potis verbinden. An D0-D7 des DIN würden dann die anderen Pins angelötet.

Hi Novski, thatnks for the link. I already noticed that TK has developed this. But the connector is way to big for my ideas. I want to use another very small connector and I want to add various of them to the core-module (one for analog modules, one for digital, one for displays, etc.) instead of one big LPT connector. Are there any informations about the maximal length of the cables? //edit: And also it seems that there are no short parallel-port-cables. The minimum I found is 1,20m. My idea is, to use cables which are not longer than 30cm.

Hey folks, there is an idea in my head. I think about creating a modular midi controller system. There should be a "core" with SCS on top. From there you can connect other modules to this core via a multipin-connector. But before I put more effort in this idea I'd need to know, if there is a limitation in the length of the cables that f.e. connect various DIN and DOUT modules. Did anyone test it? Thanks, Chris

Hey because I don't need it anymore I do sell one of my LRE8x2 boards. It's assembled already. I just need to add the three missing encoders. The encoders are non detented and do not have switches. See pic. Price: 40€ + shipping. Thanks, Chris

Hm... I can't remember this :)

NORD does in generally work exactly like this and they have just single color LEDs. I don't think it's confusing. I worked with this for many years on many stages. Never hard problems :-)

I think it's not released yet but I have a beta-version, which is not tested at my side yet. Check that out: It's not exactly what you wanted, but it's a great feature anyway! :-)

I did some changes on the layout. Because I want to put an order on the manufacture in the next days I please you, to doublecheck it. It's everytime again disappointing, to have a mistake in the layout and 10 pcbs for the trash (and money of course). So we could all safe time and nerves if some is able to check it. For testing reasons I would add the SMD-parts by myself for the start. If it works we could think about taking a PCBA service. I attached a shot of the layout.

Puh! Be carefull with advices to work with 115V/230V directly. In my opinion it would be better to use a powerful wallwart like Hawkeye suggested... I know that a wall wart is not perfect... but in the end nothing will happen to you with 5V. It looks different on 115V/230V. //edit: @ Hawkeye: So you use the LM2596 for STM and the other stuff together?

Do the LEDs really draw so much current? If you'd connect them directly I would understand it. But at the LRE the LEDs are in a matrix... it would be great if someone could somehow measure it... would be interesting to know anyways. For my DAW controller it was planned, to support USB-power (without motorfaders of course). It has 9 Displays + 9 LED-bars right next to the faders. So, if the STM-Core is not able to provide the needed current / voltage, I thought I could add a 3V3 vreg directly to the USB-jack, which has 5V. The question is, if the whole thing (STM + extra vreg) draws more than 500mA, which is the spec of a standard USB-port on a computer...

I plan to build a DAW Controller for a while now and I wonder if this still can be supplied via USB (if I don't use Motorfaders of course). But I think 9 - 10 Displays shouldn't be a problem if I use the 5V and a regulator instead the 3V3 of the STM, right? Here is a rendering:

Awesome! Great project! One thing that came to my mind when I saw the video: The main label on the displays is good to read... but the small labels on the sides seem to be very small.... can you even read it? :)

Please do a video of that stuff! BTW: It's planned to buy a cnc router and some other stuff... so if you want to create a nice design... just send me a PM.
