Hi Keith,
Sure glad that you found something to alter the situation.
On Technics keyboards the expression pedal does not directly control the audio, like the gain control on an amplifier. The keyboard processor samples the resistance value of the pedal and makes an electronic adjustment to the audio output level. This is also true for the APC/Sequencer volume control that is located on the upper left corner of the keyboard. I have found that the expression pedal and the APC/Sequencer controls interact and cause weird things to happen. Without the pedal connected, if you play with the APC volume, you can get the same problem as you have experienced.

In the keyboard there are at least five ways to control the volume:

[*]Expression pedal

[*]APC slider

[*]An imbedded control mark in the sequencer

[*]Individual volume levels for each voice via the mixer

[*]Touch control for each key that is pressed.

These are all electronic and can and do interact with each other in strange manners.
I have stopped fighting it and only plug in the expression pedal when needed. I believe that there really is a bug in the operating system.
Regards,
Walt
