The pitch wheel on my River synt, even after calibration (calibration (S-Key -> C8), doesn't always work properly. Yesterday after several calibrations it began to work properly. Today, upon power up, it began not working again so I calibrated and it jumps through numbers quickly while bring the pitch wheel to its extreme points. After several calibrations, it works pitching down, but does not pitch up. Any idea how to alleviate this abnormality? The Mod Wheel, Aftertouch, and pedal seem to calibrate properly.
