QuNexus with Korg Monotribe and Volca Keys Demo

Here’s a quick demonstration on how to use the QuNexus to play the Korg Monotribe. To duplicate this technique you will need to update the Monotribe to version 2.10 or later then connect a TRRS mini jack to the sync in port on the Monotribe (tip is gate and the second ring is CV). All the cables you need are in the QuNexus cable kit. I also synched-up the Volca Keys for a simple chord progression. The parts on the Monotribe and Volca were recorded with “flux” mode. This is simply Korg’s term for non-quantized recording. Without “flux” mode on the parts would be made up entirely of 1/8th or 1/16th notes depending on the settings of each instrument (the Volca Keys can also do quarter notes on the 1/4 mode).

  1. Hi there! Nice vid. I just bought a Qunexus and I wanted to use it to control my Arturia Microbrute through the CV ins and outs. I can’t seem to figure out how to get it to work properly. I’m new to working with MIDI and CV stuff. I was wondering if you could make a tutorial on how you got it to work. First I tried to follow the instructions on the Qunexus website; it didnt work so then I tried every combination of ins and outs on the boards and it still wont trigger even a sound. I was thinking maybe my particular controller was defective. I was told it would be pretty easy to set this up, just plug and play.. Please help if you feel so inclined!

  2. Hi Tom. I’d love to make a tutorial but I don’t have a Microbrute. However, perhaps I can steer you in the right direction. It’s not quite plug and play. Usually the process will require calibration on the synth that you’re controlling, or alternatively, the QuNexus can be configured for different voltage per octave settings. In my case all the setup was on the Monotribe, so perhaps you’ll have to start with Microbrute documentation. Also, it is critical that you have compatible cables. I used th KMI QuNexus cable kit (sold separately). Do you have the cable kit? Hope this helps. Let us know how it goes.

  3. Hi. thanks for the reply. Do you think you could make a general Qunexus to CV tutorial? I have the right cables, but not from KMI. It’s just weird that I’m not getting any sound at all, so I’m wondering if when I plug the Qunexus in I have to change some setting on it or something.

  4. No settings should need to be changed on the QuNexus. You’ve probably seen it, but this page explains the cv/gate functionality: http://www.keithmcmillen.com/qunexus/cv

    You’ll need a breakout cable. 1/8″ TRS male to two 1/8″ mono male outs. Plug the TRS end into the “Gate CV1″ port on the left side of the QuNexus. Now you have two mono 1/8″ outs. One is gate the other is CV. Make sure you plug them into the proper places on the Microbrute and things should start to happen.

  5. John, thank you for this video. Do you know if you can control Volca series by CV with QuNexus also? Can you control other parameters ( filter cut-off, pitch, amplitude) on Volca with pressure ( side by side and up and down) on keys like in this video: http://www.youtube.com/watch?v=TxohjglTleo ?
    Thank you.

  6. Hey Derek. Looks like what they are doing in the video is not a function of the QuNexus, but a spring loaded pitch bend device that is independent from it. As far as I know there is no way to send CV to the Volcas without modifying them. Obviously they all send and receive a gate clock signal, but CV is not enabled currently. Barring a software update from Korg you’ll have to look at mods to handle CV like so:

    That said, the Volcas have MIDI and the QuNexus can do MIDI through a computer with an interface, or with the KMI MIDI Expander. You can even add a MIDI output mod very easily. I’ve actualy done this to my Volca Keys:

    EDIT: With the QuNexus via MIDI you should be able to map the tilt feature to bend notes on the Volca Keys, although I have found it awkward because it is up/down versus side to side.

  7. Hi John, this is awesome! Trying to do the same (QuNexus+Monotribe), but for now I can only play a C on the QuNexus whole key range… The calibration (as described on Korg’s instructions) doesn’t seem to work (or I am missing something at this step)… Seems I’ve done the right connections between the TRS and the TRRS cables (as shown on your video : TRS red on TRRS red / TRS black on TRRS yellow)… Any suggestions ? Peace /Jé.

  8. Hmmm… If you’re getting a C then the gate must be working. Does the sound turn on and off when you play a key on the QuNexus? Have you tried other cables? Cheers!

  9. Thanks for your answer! Yes the sound turns on /off. You’re right, it comes from the cables: with the QuNexus cable set, the Monotribe “answers” in a chromatic way, but inverted (the sound holds after releasing the key and turns off when pushing). Inverting the connexions doesn’t solve the problem (at all): better to build my own cable ;-) Think KMI should include this specific cable to the next version of its cable set… Anyway, thanks again for your help, John!

  10. Solved!
    With the QuNexus cable set.
    CV/Gate mode setup on the Monotribe: step 1 = led on / step 2 and 3 = led off.
    ;-)

  11. Glad you solved it! I remember fussing with the settings as well, but I thought since you were getting gate that it must have been your cable to the CV in. Nice one!
