New FADERFOX MIDI controller system for ELEKTRON devices (12-track-design for ANALOG RYTM)


Going to look at your website now:)


Thanks for letting us know! I’m definitely buying this combo - do you have a graphic/pdf that shows the basic Rytm functionality in your midi config?


These look absolutely superb. Screw the MKIIs. Haha!


The PC12… To control omnisphere??
I’m quietly giggling here right now.


I think I would prefer led rotary knobs…
Never really understand these kinds of knobs and sliders
Especially for elektron
When playing, the values will not match the knob settings of the midi controller…

Or do I miss something? (I hope so)


led rotaries make sense when you get complete feedback data from the elektrons but this works currently only with octatrack afaik

Analog keys external knobby box

MX12 settings in setup 21 (ELEKTRON RYTM setups):
controls have same CC numbers in same row but different midi channels for each column.


  • row A: CC082 delay
  • row B: CC083 reverb


  • row C (gray): CC093 (toggle mode) track solo
  • row D (green): CC094 (toggle mode) track mute


  • CC007 volume

encoder :

  • encoder: CC025 reverb decay / channel 13

PC12 settings in setups 21 and [22] (ELEKTRON RYTM setups):
controls have same CC numbers in same row but different midi channels for each column.
(setup 22 as RYTM extension for MX12.)


  • row A: CC074 cutoff [CC074 cutoff]
  • row B: CC081 overdrive [CC075 resonance]
  • row C: CC082 delay [CC081 overdrive]
  • row D: CC083 reverb [CC080 decay]
  • row E: CC010 pan [CC031 sample volume]
  • row F: CC007 volume [CC016 synth volume]


  • row G (green): CC094 (toggle mode) track mute [CC092 scene / all buttons channel 01]


  • encoder: CC025 reverb decay / channel 13 [CC081 makeup gain / channel 13]


Thank you


Thinking right now that such controller would be really great to control a 6 operators FM synth :slight_smile:
Does your controller send SYSEX ?
E.g. to control Volca FM finer controls, you have to send SYSEX. Wonder how configurable is the PC12, or if I’ll need some translation between PC12 CC sends and Volca sysex input…


You’ll be wanting one of these for that:



Ahem, thx for the link, but nope, I won’t :cold_sweat:


how about one of these?


Picked up PC12 and MX12 at post office in the morning, can’t wait to hook them to OT :heart_eyes: I guess it will need manual (or MIDI learn) CC setup.
Not sure yet which 8 parameters will be the most interesting to have at hand per track. Any suggestions? I’m thinking 2 knobs for filter tweaking, 2-3 for delay, rest for either LFO’s or whatever FX is on the track. Green buttons on PC12 could be either ‘select track’ or ‘rec arm’ (for live sampling) … have to experiment here. Grey and green buttons on MX12 will be ‘mute’ and ‘solo’ switches. I also don’t know what to do with tracks 9-12. Either I map LXR parameters there or additional FX params of master track or selected tracks.

Edit: I just got another twisted idea about mapping for OT. Faders 1-8 would work as expected as track volumes. Fader 9 as Crossfader, faders 10-12 tbd. BUT … 8 rows of knobs, if assigned horizontally to tracks would give 12 parameters per track … little non-ergonomic but my projects usually use track 7 as live sampling track for transition trick and track 8 is master track. These two would nicely stay on MX12 and PC12 would serve tracks 1-6. Vertical divider lines will help with orientation in mapped parameters. Let’s see what comes out better.


something a cool poster mentioned on the boards a year or two ago was being able to adjust the wet/dry ratio of reverb on a track remotely via midi

maybe also try adjusting the start time of a sample on track 7 … then if it is chopped, realtime remixing of hihat grooves could be fun via potentiometer, potentially

in addition to freq/res adjustment via midi control surface, i also think the one band eq selection and gain could be valuable to have immediate access to, either for a track, or the master stereo channel.


control by sysex isn’t available on PC12…maybe later with a firmware update


also if you could mount the pc12 vertically in a custom individual bespoke stand, it would look way cool and perhaps be more ergonomically logical, the rows become columns and relate visually to the 8 channels in their new portrait presentation arrangement.


I’d love to hear your thoughts on your new setup and how you’ve configured the controllers. Also, please share pics :heart_eyes:


I first worried about the programming when I read the user manual online but it turns out to be very logical and not difficult at all.

The Faderfox MX -12 integrated into the setup very well, within minutes, controlling the volume levels on the A4 and the Virus TI (8 Parts).

The quality of the box, faders, knobs and buttons is excellent.

Thanks Mathias!


Very nice


What?! You guys don’t have perfect mental maps in your head of all 12 voices at all times?!

Visual feedback is for wimps!
