Starting a thread to see if there is a resource for VG-88 hardware repair/replacement. I just bought a new condition unit to replace my road worn unit that has most of its buttons under the LCD screen inoperable.  I've used this setup for years, and I'm sure I'm not the only one out there that could benefit from info in some internal parts sourcing.  At least my replacement unit is in like new condition, and V-Editor is still a functional software option...

The non-functional buttons can be replaced.
Just this morning I had ordered 40 of these tactile buttons to repair a Roland D-20 LA synth.

Any idea where to source these currently? Or what they're called exactly? How about the rotary encoder?

Something like this, but they come in different heights, so you might want to measure up what you have.
