Broken Encoder, VCI-400
Hey, guys.
New DJ, new to DJTT (But have appreciated all of the advice!).
I have a VCI-400 that is my pride and joy, but one of the encoders is not working. If I turn the encoder to the left, it gives me the proper value of 127 for its specific CC, but will alternate between 1 and 127 when I turn it to the right.
It’s on the left side, the left of the two knobs under the dedicated FX knobs. I thankfully haven’t had a mapping where I needed it, but I’m planning a massive mapping overhaul for my Vestax, and really would love to try to implement it.
I had a similar issue with the browser encoder, but taking my Vestax apart and using an electrical-component-sensitive dust removing spray resolved the issue for that knob, but not for the one I’m still having trouble with.
Will re-installing the firmware fix the issue?
Thanks,
Alan Wayside
Did you ever figure out a fix for this? Usually cleaning the encoder will resolve the issue.
In this order (from simplest to hardest fix)
Flash firmware
Clean encoder
Replace encoder
Dumb question - how do I go about flashing the firmware on a Mac?
That makes sense.
I’ve already cleaned the inside, I guess I’ll look into the firmware.
I went here;

I downloaded the installer, I downloaded the new firmware. I made sure to turn the VCI-400 on in it’s upgrading mode and ran the program.
Upon dragging the audio file (as specified), it gave me the following error.
Is there another way to reset the Vestax? I may need to do that first.
Thanks guys. I appreciate this.
You can’t unless you install an older version of OS X which the updater works with or you install Win via Bootcamp/Paralells.
I heared that VCI400 sometimes got problems with knobs and faders. I think there is no way out but changing them 
All controllers and mixers do over time, it’s just regular wear. Keep in mind the 400 is as old as the original S4 so things are bound to go wrong after so long.
Btw! This manual shows how to open up the unit to actually replace the part. I’ve had no luck tracking the part number and in all honesty getting the exact spare might be close to impossible these days. I’d go out hunting for a brick unit you can salvage components form if you really want to stick to the 400.
