Ju Control (JuCtrl)

31 posts in this topic

but I do have a preference for faders for envelopes

 

No problem, sometimes I prefer faders & pots as well, especially when parameters should be tweaked during a live session and each fader/pot has a dedicated assignment anyhow.

 

Such a PG-300 clone is a really easy entry point into the MIDIbox universe ;-)

No programming skills are required if MIDIbox NG is used, since it provides an (hopefully easy to learn) configuration format.

 

I found a SysEx specification under http://www.vintagesynth.com/roland/sysex.php

And based on that I created a .NGC file to demo the configuration for a few control elements: http://svnmios.midibox.org/filedetails.php?repname=svn.mios32&path=%2Ftrunk%2Fapps%2Fcontrollers%2Fmidibox_ng_v1%2Fcfg%2Ftemplates%2Fpg300.ngc

You've to upload this file to the SD Card via the Filebrowser in MIOS Studio after the MIDIbox NG firmware has been installed.

You can also edit this file in MIOS Studio later.

 

It's incomplete (because it's only a demo), but as you can see, adding remaining parameters will be straightforward. Just copy&paste the event definitions and adapt them...

If you need more guidance (and if the Manual doesn't give you the infos), just let me know and I will explain in more detail.

 

For the MIDIbox NG you would need following modules:

- MBHP_CORE_LPC17: http://www.ucapps.de/mbhp_core_lpc17.html

- SD Card: http://www.ucapps.de/mbhp_sdcard.html

- MBHP_AINSER64 for up to 64 pots & faders: http://www.ucapps.de/mbhp_ainser64.html

- MBHP_DINX4 for up to 32 buttons: http://www.ucapps.de/mbhp_din.html

- MBHP_DOUTX4 for up to 32 LEDs: http://www.ucapps.de/mbhp_dout.html

 

Kits for these modules are available in SmashTV's shop: http://www.midibox-shop.com

 

The MIDIbox NG firmware is located under http://www.ucapps.de/mios32_download.html and gets frequent updates - just follow the progress in this dedicated forum section: http://midibox.org/forums/forum/46-midibox-ng/

 

Best Regards, Thorsten.

@TK. This is very helpful to visualize what would be required! Thanks so much. I have to wrap up a couple other projects before tackling this one but I am fairly sure that this will be the way to go for my uses. Even if I didn't use the MIDIbox platform for this I can now see that it would be simple enough for me to understand for other projects.

Hi all, 
just found this topic as I'm completely new to this but looking to build a reallly simple single knob controller for my alpha juno to control just one sysex parameter via a rotary encoder.
I was thinking I might be able to use this project as a base and just leave out what I don't need, (LCD, etc) 

Would this be possible, or would it end up being more trouble than just writing one from scratch?

Thanks for any help!

i would use two encoders (first one for param, the second one for value) and a 7 segments LED display

Thanks heaps for the reply. That would be a good setup for sure, but I'm really only looking for the simplest thing possible (it's basically just to add one small as possible VCF freq knob for tweaking live, I already own a pg-300 clone but don't want to have to carry it around when literally all I can really use live is the vcf freq).

Anything I would need to look out for if tackling this, would I basically be able to use the Core module, Midi out port and an encoder? (obviously not as simple as that but just want to check if I'm on the right track before I get lost in the depths)

Cheers :)

Hello  RGordon,

Basically yes. You will need a Core8 (MIDI in/out) Module and a DIN-Module (for the ENCoder).
