NMG2 Open Source Editor

Ah, there should be a file named "g2editorfmx.xml" in directory 'C:\Users\<user>\AppData\Roaming\'. Try to find it and delete it.

It's what in Delphi is defined as GetHomePath, because of the different platforms. Maybe it's better that I put it somewhere more easy to find and also to add some checks preventing the thing you encountered... Confused

Hope you can fix it!

It may also be that findnext will get into a cycle following windows hard links .. or what was the windows word for that again ... the directory structure is a bit messy since XP ...

I updated the editor to v0.3 and made the following changes:

- Cleaner and faster termination of the USB connection on closing of the application. This bugged me a long time, but solved this by just sending a reset command to the usb interface on closing.

- Changed the location of the ini file “g2editorfmx.xml”. On windows this will be in the application folder, on Osx this will be in the documents folder.

- Added functionality “Auto assign midi to knobs”. This is for engine owners who want to use an external midi controller.

I tried to make this before on the previous editor by making an extra midi connection to the editor, but I wasn't really happy with it, because you basically had to run the editor all the time, and also the midi connection wasn't very stable.

Now I've implemented it differently, you can assign midi cc's to the buttons and sliders on parameter pages that are stored in the ini file, see picture below.
On the application settings there is a knob "Auto assign midi". If you enable that knob, the controllers are automatically assigned to the parameters associated to the buttons and sliders on patch load.

This means that the "in memory patch" will be modified, because midi controllers are stored in the patch.

- Changed the patch file browsing tree. Sub directories are only read if you expand a directory in the tree, so the application won't freeze if you accidently enter C: as your root patch folder Wink

- A number of small bugs.

- Updated help file: http://www.bverhue.nl/G2editorFMXHelp/G2_editor_fmx_help.html

If you want to try out the editor you can find it over here: http://www.bverhue.nl/g2dev/?page_id=17

Thank you again for that incredible work, and congratulations.
It works fine on OSx Mountain Lion.
The only thing I couldn't understand is : how can one change morph range? I couldn't do it with Ctrl click.
I really LOVE all the new functions you implemented and the fact this editor is compatible with so many OS.

Thanks xav!

You are right, forgot to build the Ctrl+click in for the morphs. However, you can also set them using the sliders on the "Param" tab which has a subtab "Morph assign".

Just tested some more and found a number of other problems with the morphs.

And I also found someting else Exclamation

If I assign a Midi CC to parameter "Clk run", for example and I switch to the clavia editor, I get error message "Version corrupted, Ctrl assignment problem".

This might be the same problem Antimon found...

So, this is a bit more serious, I'm taking this version temporary offline till I fix it.

Thanks very much for testing!

Ok, I've put a new version v0.35 up.

The problem with the “Version corrupted, Ctrl assignment problem” error message in the Clavia editor had to do with some illegal controler assignments.

For example, it apparently isn't allowed to make a controller assignment to patch parameter "Volume level".

So now I've I have disabled the assignment of controllers/knobs/morphs to parameters that are not allowed to have them. Hopefully I found them all.

Also fixed some problems with the morphs, Ctrl + mouseclick included.

Ok, I managed to get the USB connection between Android and the G2 going Smile

It wasn't as difficult as a I feared, but there are a couple of requirements for the tablet:

- The Android device must support "Host USB" mode
- You need a USB OTG (On the go) cable

I'm happy with this because these Android tablets don't cost a lot of money, I have an Acer A1-810 which supports USB host mode, and costs about 175 euro.

I ran the editor, but the full application is much too slow to be of any practical use and also the screen is too small for the application.

So I'm going to downscale my ambitions for the moment, and first make a simple G2 controller app for Android. I'm thinking loading patches, setting variations and some parameters.

Couldn't resist making a little application Smile

It isn't much yet, just loading patches/performances and changing variations, but it responds well and is just fun to play with.

For anyone interested in the programming part of making the Usb interface working on Android with Delphi, you can find some demo code over here http://www.bverhue.nl/g2dev/?p=65

If you have an Adnroid tablet supporting USB Host mode, you can give the application a try. You can download an experimental version over here http://www.bverhue.nl/g2dev/?p=108 and read some instructions how to install and use it.

It's not much more than a controller at the moment, and it may crash now and then, but has some potential.

The problem of the usb interface is mostly tackled, at least, on my acer a1-810. The crashing happens mostly when sending a lot of parameter messages to the g2, for example by moving a slider up and down with high speed, so I had to put a limit of 20ms on that, which in turn causes latency. So that's something that remains to be solved.

Another problem is how to implement a complex patching interface on a small screen and a slow processor.

Waw, on a tablet? Great.
I have a dream : a tablet G2 editor with a pedal. When you select a parameter (touching the screen) you could change its value with the pedal. There is a gap between real controllers and display (like for example touch osc). It's funnier to tweak real buttons or pedals than virtual sliders on a tablet. So with that tablet editor with a pedal, it could be easy to edit with one foot on the pedal, one hand on the screen, and the other (hand Wink

) on the keyboard of the G2.
Your editor running on a tablet seems to be the first (and hardest) part of my dream.

Hi, after some recovery time i am back in the studio now and switched my g2 on again.. Nice progress with the open source project.. Just trying the 0.35 fmx beta and want to try the hidden modules now since i found them most promissing on my last try..

The fmx editor opens on osx 10.8.5 and connects fine with my G2.. but.. i cant load patches from the disk..and when i try to safe a patch i get the error message in the attachment. Access violation at adress 0074183A, accessing address FFFFFFFE.

Is that a known problem?

greets
Sven

Hey Sven, good to see you back!

I didn't know about that error. I'm on 10.8.5 also and haven't seen that error message.

What have you put in the "Applications settings" "Patch directory" edit box? See image below.

The idea is that you put the root directory of your patch files in that edit box, then if you press "Refresh" on the Patch tab, the directory tree and files should appear. Seems to work o.k. here...

And Xav about your dream, the best thing I can think of is to build some function into the tablet application by which you can easily switch the foot controller between patch parameters. Are you using one foot controller or multiple?

Waw Brunov, it would be great!
For the moment, I only use one pedal, plugged in control pedal input.
Maybe the best way to do that would be to propose to choose a Midi CC for this purpose (pedal, wheel or midi incoming data).
Thank you very much to take that idea in consideration.

Do you think other tablets could be better than the Acer A1-810 to host the editor? Maybe the wish to edit from a tablet is too ambitious for nowadays gear.

Just a thought about tablets, has anyone tried a Cintiq Companion?

http://cintiqcompanion.wacom.com/CintiqCompanion/en/

It may not be small (and cheap) enough for what you are looking for, but it could run the Nord Modular G2 Editor along with a DAW...

Cheers!

Right Scannari,
That should be a perfect combination, but so expensive...

brunov · Posted: Sat Mar 15, 2014 12:10 pm Post subject:

It all depends on what you want to do with the tablet.

I agree that the little acer tablet is not much use for patching, even if I would be able to create the user interface for it.

I want to use it more as a sort of controller for loading patches or assigning controlers, that kind of thing. Maybe usefull for someone with a small mobile setup with a g2 engine.

If you want to be able to edit patches on a tablet, I guess you'll need a windows based one for the moment.

Hi Brunov,

I posted this video because it may give you good ideas (interaction from the editor with an android/iphone tablet).

The editor works on my android (a very small phone) with Remote Desktop. I noticed that the only one who often speaks of this alternative is jksuperstar. I know this is not ideal on a stage/live.

In my case I use this alternative since the late 90s in several circumstances.
I remember the first time I was fishing on a lake in the middle of nowhere and I was playing with my g2 (YES! with sound!). Very Happy

I tested several remote applications in the past. How to move around the screen works really well with Remote Desktop. In the video I play with some functions in the editor and I created a small patch. No problem to connect the wires!

brunov · Posted: Tue Mar 18, 2014 8:19 am Post subject:

Amazing you can do all that on such a small screen! And it all responds quite fast.

Yes, I knew of course of remote desktop but hadn't thought of using it on a phone. Thanks for showing, gives me something to think about Very Happy

Yes, android version is well done.
