I finally got to bending my yamaha pss 470.
The fun is endless, so i recommend getting one and opening it up.
It is one of the cases where the effort is rewarded in almost every connection you try smile
In fact, the bents are so many and sound so good, that the problem is managing space or chosing for only the best bents...
I ended up with 9 pots and I only worked on one chip smile. more, next time.

Anyway, since it sounds so good and there's so much more to do later, it is a pity to have it out of sync.
Does any of the pros smile know of a way to get it to listen to trigger or midi clock?
The highly liquid boards are reported incompatible...

Single best board for bending. Like you said, almost EVERY single connection you can finagle yields something worthwhile.

Not too sure about adding MIDI; I'm not that pro.  A decent workaround is to use sidechaining to keep bent modules quantized in real time.
