Is it possible to control a Moogerfooger MF-107 FreqBox with a Kaoss Pad?
I don’t see why not. Run the Line Out of the Kaosspad to the Audio In of the 107. If it works, it works!
Is it possible to control
Line Out of the Kaosspad to the Audio In of the 107.
This is not “control.”
In order to control the parimeters of the FreqBox (FM Amt, Frequency, Wave) you would need to send the MIDI out of the Kaooss Pad to a MIDI to CV converter and then to the 107. It should work fine I’d imagine. Most likely somewhat like using the Voyager touch pad to control.
Yeah, that’d work. I misunderstood at first. Sorry for the confusion. 
MIDI OUT to MIDI to CV converter to whatever parameter(s?) you’d want control of. Don’t forget TRS cables!
Nope.
You’d be sending CV, which works fine on TS cables. And in addition, you may plug any combination of TS cables and TRS expression pedals into the MF-107.
Ouch at Voltor… 
The CV is on the ring on the 107’s though. Assuming that he’s using an expression pedal as well as the MIDI to CV converter of his choice, he will need TRS cables so the CV doesn’t get shorted out. From the 103 manual: “When connecting one or more pedal control input jacks to a source of external voltage such as an analog synth or MIDI to CV converter, you should use patch cords with tip-ring-sleeve phone plugs. The ring terminal on the plug should not be connected to anything so that the MF’s source of +5.7V is not shorted out. Or, if you don’t plan to use any expression pedals [or Voltor boxes ] with your MF, you can use patch cords with regular two conductor phone plugs. These will short out the +5.7V supply to the ring contacts. This voltage is current limited…etc…”
Basically, if there are 2 conductor phone plugs in the inputs, it shorts out the internal voltage, rendering any expression pedal, ribbon controller, Voltor box, etc, useless.
Yes, the 103 manual. The 107 manual:
PEDAL INPUTS: All pedal control input jacks are 1/4” tip-ring-sleeve (stereo) phone jacks. The sleeves are grounded and the ring terminals are supplied with +5 volts which is current-limited. The tip terminals receive the variable voltages from the pedals.
An expression pedal for use with the MF-107 should contain a 50KOhm or 100KOhm linear taper potentiometer which is connected from the sleeve to the ring terminals. The potentiometer wiper is connected to the tip terminal. The pedal cable should be shielded, with the shield connected to the sleeve terminal.
With the MF-107, You can use any combination of expression pedals and cables that carry CVs. > > Regular tip-sleeve cables work fine with each input, as there is a > separate current limiting circuit > for each control input - so you won’t burn anything out. > Applying a varying voltage to the tip terminal of a pedal control input jack has the same effect as turning the corresponding knob. Note the voltages here are summed with the voltages from the front panel controls. You set the minimum voltage with the front panel controls. The Freq. In is the only control that accepts a negative input, as it can aceept a -5V to +5V Input. All other control inputs are designed to accept zero to +5V inputs. Do not exceed these ratings.
EDIT: I can confirm expression pedals DO work when a TS cable is plugged into another control input.
Well that’s interesting. Now I need to get a 107 to try this for myself! 
I was unaware of the difference in circuitry on the 107. I’ll take my leave humbly from this thread.
That’s alright, Volt. It’s not a big deal, only a few bucks per cable (I use all TRS plugs on cables to a homemade patchbay).
Doesn’t hurt to RTM, though
Peace
