How to Fix Unwanted Jog Wheel Vibration In Clubs
One rarely known but sometimes serious side effect of using controllers in clubs is jog wheel vibration. Without a motorized platter, some jog wheels can start to move in unwanted ways when introduced to heavy vibration. Unfortunately, big bass is a required environmental conditions of most clubs. This is not common to all controllers but if you happen to have this problem, here are a few ways to fix it.
Vibration in clubs has plagued DJ gear for years with turntables and needles alike falling prey to poorly built DJ booths. Various techniques have been employed to remedy the problem as it results in a serious problem when playing traditional vinyl: low end feedback. With DVS systems this is completely eliminated but controllers are now seeing issues as well.
“Severe bass in a room can cause a jog wheel to move in various directions, sending out unwanted pitch bend messages – instantly destroying a good mix.”
All controllers that have jog wheels are exposed to this risk, although some designs seem to be more susceptible than others. Here are the solutions we are aware of, in order of preference, based on the the least side effects.
Reduce vibration by providing cushion
If planning on playing in a club, it is wise to bring along a thin layer of foam to provide a cushion of vibration. In almost all situations this will solve the problem of jog wheel rotation but can take a bit of room in your DJ bag. I particularly like the cushion because it also allows the controller to sit on top of turntable, which is often the only space available.
- Pros: No performance downsides for the controller
- Cons: Takes up room in the gig bag.
Tighten the jog wheels
The fundamental problem is when the low end vibrations become more significant than the natural mechanical resistance. In laymans tems, the bass gets strong enough to move the jog wheels on their own. This can be easilly improved by increasing the jog wheel’s tension. Newer models of the VCI controllers, for example offer the ability to tighten their wheels making it difficult for them to turn accidentally.
- Pros: Elimantes the problem permanently
- Cons: Not available on s2, s4, and VCI-100. Changes the pitch bend response.
Put the jog wheels into FX mode
For the VCI-100 controllers, DJ TechTools offers a mode where you can put the jog wheels into “FX mode” controlling effects instead of the decks. In this mode, slight movements will cause no effect on the mix and keep things running smoothly. We are about to release a special s2 and s4 mapping that will also enable jog wheel effects seen in my NI videos very soon!
- Pros: Always on instant effects. Easy to toggle on/off
- Cons: Disables transport control
Kill the jog wheels
For the VCI-100, which was the first controller to show this problem, Vestax enabled a command that can turn off the wheels entirely. Just Press both “scratch or jog seek” buttons at the same time and look for the jog wheel lights to shut off (requires firmware 1.2 or above)
- Pros: Truly gets to the source of the issue
- Cons: You will lose all transport controls
Disable pitch bend
For many DJs that rely on sync and have quality beat grids, pitch bend controls may not even be required. In this case, you can go directly into the mapping files and remove the pitch bend commands entirely.
- Pros: A permanent, non-hardware solution.
- Cons: Removes all ability to pitch bend during a set.
