Anyone know where to source these? Guess I could just install 1/8" jacks. I just read in the manual that decay and glide can be controlled continuously with these jacks. It says to use a footpedal, so I guess that means only a DC signal?
I’ve replaced the 0.206" diameter Switchcraft S-260 plugs on mine with regular switched stereo 1/4" plugs instead. I can now use, either a (modified to use TRS jack) foot switch (normally closed contact between Tip and Ring) to turn on/off the glide, or an expression pedal (modified with 10 meg audio taper pot) control the amount of glide (up to the maximum time set by the panel knob). As per suggested in the original Minimoog D operation manual written by Tom Rhea (not the plug size substitution, but rather the use of a foot switch or expression pedal).
can you hook up CV to these?
Absolutely NOT. That’s why Moog put smaller 0.206" sockets instead of the usual 0.250", to prevent someone from sending CV to these, using regular 1/4" Moog patchcords.
If you don’t want to replace your existing Minimoog plugs, but still want to modify a footswitch, or expression pedal, using Switchcraft S-260, here’s one place you can buy the connectors.
Digikey also has them listed, but none in stock.

True… they’re not designed for direct CV.
However it is possible to use a vactrol which will convert incoming voltages to resistance.
The big problem is that not all CVs have the current necessary to drive the LED in the vactrol and would have to be inverted anyway.
(a vactrol is a sealed device with an LED at one end and a photocell at the other. The brighter the LED, the lower the resistance.)
Either way- stock, no. Not possible.
Slightly modded, yes. Entirely possible.
So a passive footpedal,the 1120 foot controller won’t work.
You can use a passive controller pedal (yes the 1120) in the glide jack (variable resistor between tip and ring of TRS jack) to vary the glide amount. You need the front panel glide set to max and glide switch ON for this to work.
Can’t do that trick with the decay though.
Isn’t the 1120 rather an active one ? It puts out from 0 to 4.5 volts, and works with a 9 V battery.
Yeah if it’s an active pedal then it won’t work. I may had been wrong about the 1120. Must be passive.
A modified (to use tip and ring) Moog EP-2, or Roland EV-5, or Korg EXP-2 would do (all passive pedals). Provided that the male jack be changed to Switchcraft S-260.
the manual says the switch is set to “off” and decay can be altered with a footpedal as well.
Most stock foot pedals will not work that well for glide.
The foot pedal is being used to substitute for the glide pot electrically.
Since the stock glide pot is a 5 meg pot and few, if any foot pedals sport 5 meg pots, at best you’d get some control over the glide times, but certainly not the full range available.
Most foot pedals max out at about 250K or 1/20th of what the front panel glide knob provides.
