Helix Bug Reports in Helix Posted August 9, 2019 After the HX stomp update to 2.81, there was a serious problem with the expression pedal . Activation of the expression pedal effect is assigned to 5% .The problem is that when the power supply to the stomp and finding the pedal to 0% (off effect) after some time (a few minutes...10-20) zero position gradually begins to shift upwards despite the fact that the pedal was not used.Accordingly, the effect is included in the unplanned time.!!! When restart the HX stomp ,pedal position is again shown at zero!And again through some time the percentage is growing!!!!Someone had such a problem? P.S> BACK to 2.71..!!!The problem is gone !!
