weird Mod wheel bleed

weird Mod wheel bleed

2017-09-08 by wasteking1@...

Problem with my PEK:
any ideas of why a program that ive used for years now plays often out of tune because the mod wheel is set to affect OSC 3 freq (amount 70) -- but 90% of the time while the wheel is set to the bottom IT STILL AFFECTS THE FREQUENCY--- and raises it-- i have to manually lower the 'amount setting' for the wheel to zero to get the sound back to normal pitch--but the tune historically requires me to use the wheel set to raise that oscillator pitch for a special effect ,.
its like the modwheel stays 'part way up' even when it is set all the way down. This only happens on that one patch and ive had that patch for years previously with no odd effect.
any ideas on whats up--or how to get it back to normal?
It has a sequencer doing a short loop like an arpeggiator so i hold the sound and move the wheel-- but clearly it plays a raised pitch from normal most of the time. but i can get it down occasionally .
could the wheel get 'stuck' electronically--not physically, and not return to zero?

It seems odd like it’s not merely a calibration issue but I suppose it wouldn’t hurt to try it to be sure.

From the instructions for the PE conversion it contains the mod wheel calibration procedure as follows:


Finishing Up: Calibrate the Pitch and Mod Wheels

14. Turn the mod wheel all the way off (down), and while also holding the pitch wheel off, hold down Reset and press 4 on the keypad.

Return the pitch wheel to center, and hold Reset and press 5 on the keypad.

Move the Mod wheel all the way on (up), and while also holding the pitch

wheel all the way on, hold Reset and press 6 on the keypad.

Please note: There is no visual feedback that the calibration is occur- ring and the numbers—4, 5, and 6—will be entered just as if you are changing programs. This is normal. If, after calibrating, the synth seems not to be tuned to concert pitch, calibrate the wheels again.
