Hi here!

I reactivated my Roland JV-80 after a long break and the PitchBend/ModWeel and C1 are not working localy.

External MIDI gear can control Pitch Bend and Modulation inside JV-80.

In test Mode pitch Bend and Mod Weel and C1 Fader reacts properly according to Service Manual.
I can also see C1 values moving in PATCH : PLAY->CONTROL mode -> "C1 ASSIGN".

[Update]I can control external MIDI gear with JV-80s PichBend/ModWeel and C1. So its for sure something with routing inside JV80.

What could it be?

Maybe a hint can be that the PRESENCE Fader also dont work = But at the other side it is just an analog EQ - so here maybe just the fader is broken.

Update #2: May the magic happens behind the TRANSPOSE button. Have to check it when Im at home.

Update #3: Well, TRANSPOSE button does not help so far ...

Best!, Ready

Me again!

It seems that also TRANSPOSE switch is not working (it light up, but there is no effect). Well, I can change the Transpose Value in the TUNE & FUNCTION menu, but pressing TRANSPOSE button takes no effect then...

So it is still a lack of internal connection from the controllers: Pitch Bend Weel , Mod Weel, C1 Slider, TRANSPOSE knob...

I can easily controll the pitch via LFO 1 oder LFO 2...

Strange...

UPDATE:
Problem solved!
The thing is that my keybed was not attached. I fight the red glue problem in parallel. With keybed attached the JV80 reacts normaly to PitchBend and Modulation. ))
