Hi all,
So I am having problems with the joystick, mainly the pitch bend.
When used pitching up cuts the sound out. Moving it slowly up the pitch goes up, then down then cuts out. When moving the bender down the pitch goes down, but way way down so the sound is barley audible.
Pin 7 of IC 10 is giving 1.986V with the bend in the centre, 0.012V all the way down, 3.99V all the way up.
Pin 2 of the bend pot gives roughly 2V centre, 4V all the way down and 0V all the way up. This is the opposite of what I would expect.
Other readings that I thought might be relevent: Pin 7 of IC38, which I assume is the output the service manual refers to, is 3V where the manual says it should be 4V.
Also pin 7 of IC35 is 0.8V bend centre, 2.5V bender down, -3.5V bender up. Again, is this correct?
Thanks as ever!
Al
